Air seeder cArts REsEARCh REpoRT |

What's in a cart? seeder to make sure it can cope with everything from canola and lupins to mono ammonium phosphate.

Its job is to accurately measure and deliver a particular amount of product from the cart to the seeding bar and be able to continue to do that.

Some of the air seeder technology is tried and tested and has not changed much over the years, for example, the metering systems.

But some aspects of the air seeder are all about change — and progress.

Control panels and screens are now far more common on air seeders in a similar trend to tractors with guidance and telemetry equipment.

And safety is also much higher up the priority list.

This can be seen by the addition of features such as ladders, walkways, handrails and lighting.

Sales of new air seeders have been reasonably sluggish in the past decade or so thanks primarily to poor seasonal conditions and earlier this year, the federal government announced a refundable tax offset for the purchase of eligible no-till seeders.

Having done the rounds of a few of the major agricultural field days in September and October, though, many machinery manufacturers have reported interest in the tax offset is high but few producers have taken the next step and ordered, or bought, gear due to the tax break.

Recent rains in some of the key grain growing areas in eastern Australia may change that scenario as it looks like many will enjoy the rare double of good crop yields and high prices.

We’ve thrown in a few buyer’s tips when looking at air seeders, helped by the NAS survey data which showed the top three

F ew pieces of machinery are more important to a grain grower than a seeding bar and cart, or air seeder. Depth of seeding, row width, seeding

and fertiliser rates all play a key role in the successful germination of a crop and the air seeder is a vital part of the equation when it comes to getting your crop off to a good start.

In this report we take a look at the most popular brands of air seeder carts (by number) from the Kondinin Group’s National Agricultural Survey.

As well as a few key issues you should look for when buying an air seeder.

While the air seeder is without doubt one of the workhorses of modern grain farming, subject to thousands of hectares of toil, the modern versions are not only robust, but highly accurate and intricate bits of gear.

On the surface, it’s a large bin, or several bins, with a bunch of hoses, a few fans, some metering gear and wheels.

But there’s a whole lot of technology and engineering which goes into an air

issues for air seeder owners were wheels/tyres (reported as a problem by 32 per cent of the owners surveyed), electrics (26 per cent) and calibration (26 per cent).

Costing upwards of $300,000 for a seeder and seeding bar, the purchase decision could not be much bigger and we recommend doing your homework and getting as much hands-on time as possible, or a demonstration, before buying.

a 15 per cent Refundable tax offset is available for new seeding gear (as long as it meets strict criteria) through the federal government’s clean energy Future plan which aims to increase soil carbon and reduce emissions

Tax break adds up for air seeders

A key word in the process is “eligible” when it comes to the conservation tillage seeder.

By definition from the Australian Taxation Office (ATO), an eligible seeder is a no–till seeder which is:

A tine machine fitted with minimum • tillage points to achieve minimum soil disturbance and less than full cut-out (for example, narrow points, knife points or inverted T points).

A disc opener with single, double or • triple disc blades designed to achieve minimum soil disturbance and less than full cut-out.

A disc/tine hybrid machine with • single, double or triple disc arrangements fitted with minimum tillage points to achieve minimum soil disturbance and less than full cut-out (for example, narrow points, knife points or inverted T points).

A disc/blade hybrid machine with • single, double or triple disc arrangements fitted with blades to achieve minimum soil disturbance and less than full cut-out.

Primary producers should also note new air carts are only eligible for the RTO when they are purchased in combination with a new seeder bar.

I f you’re in the market for an air seeder, you may be able to take advantage of a tax break on offer by the federal government.

Known as the conservation tillage Refundable Tax Offset (RTO), the tax break has been set up to help primary producers get into conservation tillage to reduce emissions and increase soil carbon.

The tax incentive is part of the government’s Clean Energy Future Plan and if you qualify you may be entitled to a refundable tax offset of 15 per cent of the cost of an eligible seeder.

When the scheme was introduced earlier this year, it was available for new purchases of both the seeding cart and tool bar but the government then changed the rules so from July 1 onwards, just buying a tool bar could be covered.

This was to cater for farmers who may be looking to upgrade their tool bar but still use their existing cart.

There are strict eligibility guidelines to follow for the RTO and one of the first requirements is eligible seeders must be installed ready for use between July 1 this year and June 30, 2015, even if the purchase was before 1 July 2012.

Then the RTO can be claimed in a tax return for the relevant income year of the purchase.

The RTO does not apply to new air carts that are used with existing seeder bars.

Bin-mounted air seeders and seed drills or combines also qualify for the RTO provided all other eligibility criteria are met.

Further eligibility criteria involves holding what’s known as a Research Participation Certificate (RPC) and to get one of those, you need to fill in a form which is handled by the Department of Agriculture, Fisheries and Forestry.

The RPC application form includes a Conservation Tillage Survey and must be completed in the same income year the eligible seeder is installed and ready for use.

The application form is used to provide information to DAFF and the ATO about the person or entity applying for a RPC.

If successful, the RPC will be issued by DAFF and a copy given to the ATO.

For more informationMore information on the RTO is available on the ATO website www.ato.gov.au and there is an RTO hotline which is 1800 108 760.

We also recommend you talk to a tax professional or your accountant regarding the RTO.

air seeder carts are a significant investment for any cropping enterprise, so making the right decision for your business is crucial, and that’s a decision which can only be made by understanding everything involved

Plan before you purchase

If it’s a manual set up which may require cranking a handle 64 and a quarter times or changing a sprocket or slide, don’t be afraid to ask and be shown how it’s done properly.

MonitoringHand-in-hand with calibration is the monitor or control panel.

If the air seeder comes standard with a display monitor, which many do now, have a play and make sure it’s easy to use.

Navigate the various functions and pay close attention to menu structures, the way information is displayed, how robust the monitor is and how easily it can be seen (which includes adjustment for brightness and contrast).

Just because a machine comes with a monitor does not necessarily mean it is automatically much easier to use.

Having said that, modern monitors have come along in leaps and bounds compared with even five or so years ago and they are generally easy to navigate and install in a tractor cabin.

Wheels and tyresSurprisingly, this was the top issue from the NAS data. From our research and speaking with owners and manufacturers, wheel and tyre failures are quite rare.

However one of the more popular brands of air seeders did note an issue with a well-known brand of tyre fitted as OEM equipment but that has since been resolved.

Buying an air seeder is a major purchase, especially if it involves the air cart and seeding bar.Grain growers and primary producers

can expect to part with big bucks — and that means hundreds of thousands of dollars — for the right combination of air cart and tool bar.

Which means making sure you have the right cart for the job is paramount.

There are several key areas to look over before the contract is signed when it comes to the air cart and we recommend getting as much practical, hands-on experience as possible prior to buying.

CalibrationCalibration of air seeders was one of the top three bug bears, or reported problems, according to Kondinin Group members when asked in the latest National Agricultural Survey.

There’s no doubt some calibration systems are easier than others to operate but machinery manufacturers have told Kondinin Group owners quite often place calibration right down the priority list when it comes to seeding.

Calibrating the seeder is critical to ensure the right rate of seed and fertiliser is applied and it’s a job which simply cannot be overlooked if you are serious about getting a good application.

Whatever the calibration method, make sure you have a thorough understanding of the process before purchase.

With the increase in size of many of the modern air carts (upwards of 17,000L capacity), attention should be paid to the tyres, in particular the load rating.

Also pay close attention to the bracketing and mounting of wheels, including caster wheels as they can be a weak point in the design.

SafetyClose attention needs to be paid to rails, walkways and ladders.

Getting to the top of bins can be quite a trek in some cases and being up 2–3m means sure footing and plenty to grab on to is a must.

Also make sure it’s easy and safe to open and close bin lids and to operate the auger if there is one present.

Again, ask to have these aspects of the air cart demonstrated.

Another safety aspect is hitching, which can be an issue depending on whether it’s a tow-behind or tow-between design.

Hitching needs to be safe and simple, no matter what the set up.

Build qualityFinally, take particular note of the finish and potential for rust and wear points to deteriorate over time.

Poor quality finishing, even in the paint work, can lead to premature rusting and wear.

Other key areas to note are drive shafts and sprockets.

From dalby, Queensland, simplicity airseeders cover seven chassis configurations with more than 40 model variations.

Bin capacities are from 1500L to 20,000L and there are tow-behind and tow-between models.

steerable axles and castering wheels are also available.

In terms of design, simplicity has not changed much over the years. as they say, “when you’re on a good thing, stick to it”.

one of the things which has changed is the load/unloading auger design.

the augers have been improved with better balance and a new mounting system. they also have locking clamps to improve auger use on sloping ground.

the augers are hydraulic drive and feature forward and reverse operation and a steel hopper.

auger diameters are 152mm, 203mm, 228mm and 254mm, depending on the model.

simplicity offers two and three-bin models plus there are small seeds box and liquid options.

Meteringsimplicity’s metering system has not changed greatly in 30 years. It’s fluted roller design has the ability to blend product within the metering unit.

see-through panels allow the operator to see product moving and there are insert plates for smaller seeds such as canola.

simplicity mostly uses a ground drive metering system running Zero Max gearboxes but it also offers proportional hydraulic or electric drives.

simplicity has been offering its seeders with full variable rate application, still utilising the ground-

drive mechanism but with the addition of linear actuators.

simplicity believes this system to be both simple and reliable.

Calibrationcalibrating the machine manually takes about 30 minutes but the process is sped up considerably with the linear actuator option as you don’t need to count the number of crank turns and there is no trial and error in the procedure.

a range of controllers is available. the topcon e15 eagle is standard and topcon X20 and X30 controllers are also available.

Recently, simplicity added the “IB” to its monitoring options which allows other brands of screen such as a John deere 2630 or pro 700 to display the simplicity software and control the airseeder using the Virtual terminal capacity of the alternate screen.

Air and distributionthe metering units use four, six or eight outlets which feed into 76mm diameter hoses.

on larger bars the typical division procedure is the 76mm hose is used to deliver product to the primary dividers, and on to secondary heads which then deliver product to the seeding gear.

depending on the set up, the primary dividers deliver product via two, three or four outlets.

two-way systems use a 50mm line while three and four-way systems use 44mm hose. simplicity’s secondary heads range from four to 10 outlets.

oil coolers are standard and the fans are hydraulic drive with Rexroth motors.

safetyaccess to the bins on most of the larger models is via a rear-mounted ladder.

on top of the bins there’s a full hand rail system with kick boards. the ladders also have hand rails.

on top of the bins is a sturdy platform made of steel grating.

the middle hand rail swings down to allow auger access for filling.

Wheelsthere is a range of wheel set ups depending on the cart capacity including castering wheels and steerable axles.

castering generally allows sharper turns and is often suited to smaller seeding bars compared to steerable axles typically being able to carry more weight and generally track better, but are more difficult to reverse.

Flexi-coil has a range of air seeders.

the 2340 (8140L), 2850 (10,103L) and 3350 (11,528L) are two-tank models while the 3850 (13,390L) and 4350 (15,153L) have three tanks.

all models are available in tow-behind or tow-between configuration, with the option of ground drive rate adjustment or electro-hydraulic drive for in-cab variable rate adjustment.

the new 580B (20,435L) has three-tanks and is available as a tow-behind, variable drive only model.

Calibrationall models have a simple to follow, on screen calibration procedure.

the meter rollers are turned to collect product then the product weight is entered into the screen.

once this is done, the operator simply inputs a target rate and starts seeding.

Meteringall models use common metering systems.

there are six choices of meter roller to use, depending on crop type and application rate.

on all models the air manifolds swing away, allowing easy access to the meter rollers.

Air systemFlexi-coil uses a B-type distribution system.

up to eight primary lines can be used, each supplied product by an individual meter roller segment.

these feed to headers on the tool bar, which distribute product through secondary lines to the seed boot.

all models have a hydraulically-driven, dual fan system.

air supply to the manifold for each tank can be adjusted individually for different product rates, and single and double shoot purposes.

triple shoot is available as a dealer-fitted option.

Electronicsall models come standard with the Flexcontrol IV plus display — a 250mm colour touch screen with multiple functions.

Variable drive carts offer variable rate prescription seeding, data logging, overlap control and boundary control.

the screen setups can be reconfigured to suit different preferences.

the display and air seeder electronics are Iso11783 compatible.

safetyall Flexi-coils have easily accessible walkways, with hand rails which meet australian standard as 1657.

auger and field lighting are standard on all models (except the 2340 where it is optional).

the 580B features an automated, remote controlled 254mm diameter auger.

hitchingtow-between models connect directly to the tractor draw bar.

tow-behind models have dual caster wheels, which can be steered by a telescopic link from the tow hitch, enabling the air cart to track with the tractor.

the 580B has a steerable front axle.

Talk to your Bourgault dealer today to find out more about the 6000 Series Air Seeders and how they fit into your farming needs (08) 9399 9700

Morris seeders are available in a range of tow-behind and tow-between models.

the 7000 series covers 6550L to 10,910L.

a three-bin system is common on the 7000 series and provides the ability to delivery product in single, double or triple shoot set ups.

the 8000 series covers 10,690L to 23,011L and can have up to four bins.

there are several auger options, from 180mm to 250mm in diameter and a conveyor is an option on the larger carts.

CalibrationManual calibration on the ground-drive air carts is a standard procedure of metering out one tenth of a hectare by manually cranking a handle and adjusting rates accordingly.

With the variable rate system, which is hydraulically operated, calibration is via the monitor.

all that is required is inputting the actual product weight from calibration into the monitor.

Meteringa ground drive system is standard which runs a series of spiral, fluted metering wheels.

With the ground drive, rate changes are made with sprocket changes.

on the eight series, there are fine, medium and coarse seeding plates to cover different product sizes.

Air systemthe distribution system on Morris seeders is a feature of the air cart.

It starts with a piston-type hydraulic motor which drives a hydraulically-powered fan.

the fan is 33cm in diameter on the 7000 series and 43cm on the 8000 series.

there are very few sharp turns in the delivery system thanks to Morris’ patented Flat Fan divider head.

the flat divider helps keep product flow horizontal and maintains even flow to each secondary hose.

primary hoses are 6.4cm in diameter and the secondary lines are 2.4cm.

Monitorsthe standard is a Vansco monitor which shows fan speed, shaft rotation, bin levels and area sown.

topcon X20 or eagle controllers are an option for variable rate applications.

the X20 can control up to five tanks including granular and liquid products.

safetyLadders on either side of the bins provide access to a walk-through platform between the tanks.

the walk-through platform means the bin lids are about waist height and there are handrails at the top of the ladder access and grab rails on the sides of the bin where the auger is situated for filling.

hitching and Wheelsdual wheels are available on some of the tow-between model air carts and are fitted with high flotation 800/65 R32 tyres.

eight series models are also available in a quad steer design and the front axles can be offset for extra stability.

horwood Bagshaw air seeder carts are made to handle granular and liquid products in a variety of configurations.

there are two-bin and three-bin models with total capacities from 2000L to 21,000L and frame options include horwood Bagshaw’s scaribar a frame mounted, tow-behind, trailed, trike style, quad wheels and various track widths to suit controlled traffic.

tow-behind trikes use a 'walking caster' assembly while quad wheel carts use steerable front axles.

Meteringhorwood Bagshaw air seeders use the same electric-drive, fluted metering rollers for all products.

the roller flutes are offset/timed across the roller, so the product is always being metered progressively into the airstream.

this makes the air seeder particularly accurate for small seeds.

the metering shaft drives an agitation shaft which reduces the chance of product buildup above the rollers.

a metering gate below the rollers aids in the controlled flow of product and the gate lever is also used for quick bin clean out.

a simple, lever-operated blending system is standard on all models which allows switching from single shoot to double shoot, plus graduated blending of fertiliser with seed to prevent seed burn.

Calibrationcalibration can be tested by a simple, stand-still one fifth of a hectare accuracy test.

product by product calibration factors can be stored in the tractor console, and recalled for future use.

the manual calibration method is used for the ground-drive models and there’s an option to move to electric variable seed rate control which where calibration is calculated via a monitor in the tractor cabin.

as a failsafe measure, bins are fitted with viewing lenses and reflectors to ensure product is moving.

Air systemLarge capacity, smallaire fans are used and the hydra motors are easily adjusted from the tractor seat so that variation of air volume for seed types is a simple process.

a lever-controlled air manifold at the fan also allows variation in air to shoot runs (for heavy versus light product).

there’s an optional air warmer which acts on the air, rollers and air tubes if desired.

Monitorstopcon and Farmscan control systems are options available.

topcon now offers a canBus/IsoBus system to facilitate operation through compatible systems such as the John deere Greenstar.

the topcon X20 and X30 consoles offer simple, touch screen operation.

horwood Bagshaw also provides comprehensive, simple-to-follow and illustrated operator’s Manuals for all monitor and controller options.

BinsGranular bins are constructed of 2mm thick steel and internal bin surfaces are coated with a hard-wearing, durable, two-pack paint finish.

the bins have an air equalisation system to maintain constant air pressure and accurate sowing and liquid models use thick-walled plastic tanks.

safetyall models have a retractable ladder for access to the bin platforms and handrails comply to australian standards.

depending on the size of the bins, there are one or two platforms and the handrails can fully enclose the platform area.

Larger models are equipped with a steerable front axle. optional extras on the range include the loading/unloading auger and a small seeds box.

Metering and calibrationthe heart of the Gason metering system is a series of rotating, segmented rubber wheels.

the metering unit features a unique side Release meter box which allows the metering shaft assembly to be slid out to the side for easy cleaning and changing of meters for larger grains.

only a few minutes is required to change the metering. there are also reduction plates for metering canola and other small seeds.

a swing away hatch allows product to be removed from the bin and also access for weighing product for calibration.

It’s a ground-drive metering system which runs a ZeroMax gearbox, or variator.

Gason has an optional variable rate system which is driven hydraulically and electronically controlled

where rate changes can be made at the touch of a button and there’s a failsafe manual override system.

Air systema hydraulically-driven fan supplies the air, driven by an axial piston hydraulic motor.

a fully welded aluminium impeller is mounted to the hydraulic motor so there’s no external couplings or bearings to maintain.

Bins pressurise automatically to ensure maximum efficiency and no loss of air pressure or flow and a high-pressure, replaceable 10 micron filter is used to clean the oil supply.

DistributionGason air seeders are suitable for single, double or triple shooting, depending on the configuration of the seeder.

easy to operate diverter levers place seed and fertiliser in separate primary tubes or in a combination of blends.

Removable, clear panels on the side Release meter box provide a visual assurance of product diversion or meter wheel condition.

MonitorsGround-drive units have an in-cab monitor (Farmscan) as standard to show parameters such as meter shaft speed, fan speed and air pressure.

hydraulic-drive seeder carts have a range of options available when it comes to monitors which allows the operator to change rates on the go and control the flow of product from the bins.

BinsGason’s bins are made of 2.5mm and 3mm thick sheet steel. the design incorporates folded corners for maximum strength and all corners are welded inside and outside.

the paintwork is two coats of enamel baked to 120°c for 30 minutes and the small seeds box is finished with a powder coating.

Gason range delivers precision

Gason Air Seeders - used by Australia’s leading farmers

Metering systems on Gason air seeders are renowned for their accuracy and ease of operation. Testing of a Gason 1880 model by the independent Kondinin Group found that calibration was one of its best features.

“The machine performed well, recording some of the best results of all units tested, with an average seed distribution coefficient variation of 6.1% and 7.3% for fertiliser distribution.

Distribution across the machine showed repeatable results with seed distribution ranging from 6% at both 40 kg/ha and 80 kg/ha, to 6.4% at 120 kg/ha.

Fertiliser distribution ranged from 7% at 50 kg/ha to 7.6% at 150 kg/ha.”

Gason’s carefully designed meter wheels accurately handle a wide variety of seeds. The only time meter wheels need to be changed is for very large seeds like beans.

Choose from Variable Rate Technology (VRT) or Ground Drive.

• VRT allows on the go application rate changes from the tractor cab. It is perfect for integration of GPS mapping technologies.

• Ground drive is ideal for those not requiring VRT.

16 models - from 2,200 to 15,300 litre cap.

the auger housing and orifice are coated with a fluoro-polymer which is similar to a non-stick finish for corrosion resistance, reduced wear and minimal product build up.

there is large flow-through sump on each bin for tank clean out and metering auger inspection.

the bottom of the sump has a steel door held on by two eye bolts which are undone for emptying.

Calibrationall 6000 series air seeders are ground-driven and feature a hydraulic calibration system.

self-resetting, torque limiting clutches are used to protect each metering transmission from over-loading and in the event of an electrical failure, the air seeder can still be operated manually.

the hydraulic calibration is run off the same circuit as the fan system.

Air systemBourgault air carts have a class ‘a’ or straight through primary distribution system which allows product to be metered from any tank into any primary line.

Bourgault uses a two-fan product delivery system for double-shoot kits to maximise efficiency. For high rates with larger drills, Bourgault also has a high output fan option.

the primary lines are made of 150mm diameter steel pipe while the secondary lines are 63mm diameter rubber hose.

ElectricsBourgault has cab Rate adjust as standard on its 6000 series. the application rate can be adjusted for each metering auger at the push of a button from the tractor cab.

an electric actuator mounted on each transmission remotely adjusts the rate when activated by the operator.

a second control panel is located on the tank for rate setting during calibration.

the Model 591 monitor reports standard air seeder functions including fan speed, theoretical application rate, bin levels, area sown and ground speed.

a topcon X20 monitor/controller is an optional extra which performs monitor and controller functions.

safetythere are two ladders located at the front of the bins to allow access from either side. there’s a walkway and a third ladder to gain access to the bin lids and the top catwalk has an embossed steel floor with folding hand rail.

a handy safety addition is what’s known as the easy hitch. this allows the operator some slack when it comes to hitching. You only need to back the drawbar within 250–400mm of the hitch.

ausplow’s Multistream and airseeder models provide more than 20 options for grain growers.

the Multistream is available in 17 models and in tow-between, tow-behind or drawbar designs.

up to seven tanks can be used to deliver granular and liquid products including herbicides, with tank sizes of 4400L, 4700L, 2000L, 3000L and 1500L for small seeds.

there are five models of ausplow airseeders for non-liquid applications.

they have two equal tanks, either 3000L for the drawbar-mounted model or 4700L for the tow-between and tow-behind models, with optional 1500L small seeds tank.

Calibrationcalibrating granular or liquid products is via a switch box on the chassis which activates the individual metering units.

to calibrate the seeder, place a 30L, tared bucket under the primed metering unit and switch the switch box to “Run”.

Weigh the calibrated sample on the supplied scales, then enter the sample weight into the topcon X20 monitor.

Meteringthe seed and fertiliser metering units are made from marine-grade stainless steel.

each unit distributes product into either air stream at positive preset quantities of zero per cent, 25 per cent, 33 per cent, 50 per cent, 67 per cent, 75

per cent or 100 per cent to achieve the desired blending rates.

Low wear, plastic, staggered-tooth metering wheels are hydraulically driven.

a unique, multi-positional stainless steel metering flap is simple to adjust and eliminates the need for separate metering wheels or bolt-in restrictors.

Fully opening the flap allows the bin to be cleaned out.

Air systemthe standard capacity turbofan has a 19cc hydraulic motor and is capable of dual shooting up to 72 tines.

oil is filtered prior to the motor and is then used to pre-heat the air-stream.

an optional high-capacity fan is available (Multistream hd models only) which has a 30cc hydraulic motor and is capable of dual shooting up to 90 tines.

Monitorsthe Multistream has the topcon X20.

the system allows a granular or liquid metering unit to be controlled by the same controller without specialised programming or additional hydraulic components.

Variable rate technology using electric over hydraulic control provides good torque to the metering wheels.

the seeders are also equipped with a manual over-ride metering system, where the bin can be operated without electronic control, in case of emergency.

Binshigh-density polyethylene tanks are used.

polyethylene can reduce sweating inside tanks in high humidity environments, resist corrosion with low ph solutions, and lower friction properties to reduce the incidence of bridging when compared to steel.

safetyRaked ladders, large steps and chest-high rails capable of supporting a person carrying bagged produce provide safe access to bin lids.

hitching and Wheelsa heavy-duty, fully trussed chassis design has 100mm or 150mm solid beam axles and fully braced tow hitches.

1st slotThe DBS blade gives vertical cultivation, deep into hard pans or barriers and the flat leading face causes soil to burst

ahead with improved aeration and water infiltration. Fertiliser can be placed behind the digging blade, profiled, or percentage deposited with the seed as a “starter”

The patented three-slot system comprises a 13mm wide tungsten faced blade, a closing tool and a following spring-loaded depth gauge press wheel.

3rd slotThe press wheel pushes soil forward in a wave action, causing the soil to flow inwards, whilst covering and gently firming

it around with seed. Ground following will also give precise depth placement

2nd slotThe closing tool collapses soil downwards, creating a firm and even seedbed. The lower front edge tool is faced with a

tungsten profiled tile, improving durability and maintaining the width of the tool throughout its operating life. Importantly its round face reduces the amount of material that accumulates whilst passing through the ground
