1140-1/-2 1130A (Offset, Intersecting) The standard Dawn row cleaner gives maximum performance at a reasonable price. The drop forged wheels are guaranteed for life against bending and breaking. The acme screw adjustment is a detail the accountants would omit yet can really make a difference to a farmer at planting time. Every detail is about quality: acre after acre, year after year. This unit is expandable. Add a 1500 coulter to make a 1572, convert that to a narrow row unit and extract maximum value from what you already own.

Couple the evolutionary TW2 with the screw adjust unit and you have an exceptional solution for farmers who have wheat or grasses in their rotation. The TW2 is recommended as well in conventional tillage applications where a less aggressive row cleaner is desired.

The single wheel row cleaner should only be used on 15 inch rows when no other options are available. The CNH split row 1200 planters would be an example. Various 1780 models would be another.

1140-1/-2 1138F

TW2 6.25 NBP

New to the Dawn product line for this year is the 1138F stem assembly. This product can be used with the larger 14 in diameter TrashWheel, but is primarily intended to be used with the smaller TrashWheel 2. This unit is intended to be used primarily in No-Till conditions. It is an excellent solution for many farmers who are on 20 in rows, no-tilling, and still want to run a double wheel row cleaner. This stem is not available for Case planters. The teeth of the TrashWheels are lightly intersecting and cannot be run in the offset position.

Row Cleaner Theory

DiskA disc will tend not to plug yet exhibits extreme sensitivity to depth control and will move large amounts of soil. Early furrowing discs motivated the evolution of the toothed wheel row cleaner. Notched Disk The notched profile will marginally minimize the sensitivity to depth control Semi-Toothed Notched Disk Represents shifting the toothed row cleaner design back towards the disc end of the spectrum. Exhibits high sensitivity to adjustment. TrashWheel® The original row cleaning wheel. A middle ground between disk and rake. Moves residue with far less soil disturbance and sensitivity to depth. TrashWheel 2® Maintains the guaranteed durability of the TrashWheel® while opening more area between teeth. Effectively moves residue with minimal soil disturbance. Swept tooth profile sheds residue. Less depth sensitivity than TW1 VariWheel® Shifts row cleaner closer to rake, though has better durability and performance in corn. Functionally exceptional in most conditions though the thinner tooth cross section is not as durable as TW,TW2 Rake Type Wheel Row cleaning with minimal soil disturbance. Lacks durability. Not aggressive enough in heavy residue.

1140-2 Also referred to as NBP or narrow back plate. This mounting bracket should be used on 1790’s, and larger Deere Planters where row unit travel is essential. Also on Deere planters in rocky areas. Can be used on All Deere planters 7200 and Later.

1140-5For Deere 7000 planters and Kinze planter produced before 1993.

1140W-1/2On the 8000 Series, White had the great idea of shifting their hole pattern by a quarter inch and now you have to buy this special mounting bracket. Effectively any unit can be made special to fit the White 8000 series.

1140-3 and 1130C The Case IH row unit takes this mounting bracket and stem combination. Will fit the 900 series and up.

4010 4010-DBS (shown with optional depth bands) 4010-12.75 The model 4010 is generally recommended for farmers who are in a 50/50 corn and soybean rotation. If seeding corn into standing corn is a possibility the 4010 should not be recommended. The floating character of the unit allows it to follow the terrain more precisely with fewer adjustments. This unit still retains a screw type adjustment of the absolute lower depth. The 4010 can also be converted to a rigid non-floating row cleaner if the need should arise. This is an excellent unit for the middle ground between No-Till and Conventional Tillage.

1572 1130A (6 Hole Stem) The model 1572 has had a band of loyal followers for several years prior to exploding onto the scene for the spring 2005 season. The 1572 is simply the best No-Till attachment. The essence of this unit is that it utilizes the coulter blade for multiple purposes: to cut a line through the residue, to lightly till the soil ahead of the planter opener, and to prevent residue and mud buildup on the row cleaning wheels. By parting the residue down the center of the row, the performance of the Trashwheels is greatly enhanced. By placing the trailing edge of the blade in the primary plug point of the row cleaner, this unit is essentially impossible to plug. Period. If corn on corn is the problem this unit is a proven solution. The 1572 also forms an integral part of the Pluribus Strip-Till unit.

1572 1130A-12.75 (4 Hole Stem) This configuration is used by default on the JD 1770NT for clearance issues. Coupling the new style TW2 with the 1572 is possibly the best variant of the 1572. The 1572 configuration allows the unit to handle very high levels of residue. The TW2 effectively moves the residue yet does not move as much soil. In highly tilled fields where the standard 1572 might be a bit aggressive, this unit will move less soil and allow the Trashwheels to be raised an inch higher. Another example: you have just entered a really wet wheat field or are second cropping into freshly harvested wheat and you notice you are hair-pinning a bit. Just remove one bolt to drop the coulter. Then shift one Trashwheel to the front hole and you have an excellent setup for your conditions. It’s tough to go wrong with this unit.

2003 (6 hole Stem) 2003-12.75 (4 Hole Stem) Narrow Row Coulter Combination The model 2003 is the preferred unit for 15 inch rows. It is also the most commonly used unit on 20 inch rows. On this unit the coulter blade is not intended to be acting as a tillage device, although its position does cause it to fracture the sidewall on one side of the row which aids in closing the slot. Rather, the blade is parting the residue off center so as to enable the row cleaning wheel to act more effectively. Looking at the above drawings, one might think that the row cleaner is not going to clear over the center line of the row. This is not true. The row cleaner is going to grab all the residue from the coulter blade over, not just directly in front of it. By always pushing the residue to one side, and incorporating the self cleaning aspects of the 1572, this unit is virtually plug free. It can easily be converted to the double wheel 1572 and vice versa.

2002 Includes 1520 Coulter Combination Row Cleaner Ahead of Coulter In certain areas, such as Nebraska and western Iowa, farmers tend to want a unit with the row cleaners floating in front of a No-Till coulter. Ridge-Till people like this unit. On this unit you have a screw type adjustment setting on the lower depth of the row cleaners, which will float up from that point. Depth bands can be added to increase floatation in softer soils. The row cleaners can also be locked down if necessary in severe residue. This unit is an extension of the 1520 basic coulter assembly.

2000 Includes 1572 Coulter Combination Row Cleaner Ahead of Coulter Liquid Fertilizer Injection The model 2000 is similar to the model 2002 but has the addition of liquid fertilizer application at approximately 1.25 inches from the centerline of the row. This unit will work for smaller quantities of fertilizer. For instance, 15 gpa of 10-34-0 would be typical. The fertilizer depth has three settings: .75 inches below seed, at seed, .75 inches above seed. The position of the fertilizer tine can be fine tuned with the screw adjustment assembly. This unit can also be converted to a model 1572 with very little additional cost. Again, this unit is commonly used in Nebraska.

2005 Includes 1572 Coulter Combination Row Cleaner Ahead and Behind Coulter New for this year is the model 2005. This product exemplifies the modularity of the Dawn row cleaner system. This is a system designed to introduce a staggered arrangement to the TrashWheels so as to enable performance in very heavy residue. Most notably, when coupled with the smaller diameter TrashWheel 2, this is a unit that will enable full width row cleaning on 20 and 22 in rows. This product is essentially a reconfiguration of basic Dawn components.

300287(RH) 300288(LH) “Zipper” Closing Wheel Kit for 3004 Frame Mounted Fertilizer Opener These kits add a CurveTine closing wheel to the model 3004 for use with anhydrous ammonia. This unique setup replaces the arm for the TrashWheel also, creating a walking beam arrangement between the two rotating components. By doing this you not only add the ability to effectively seal ammonia but add increased depth control to the row cleaner at the same time. This setup creates a very efficient (low horsepower, high speed) way to put down anhydrous, fall or spring. The closing wheel features a simple angled hex block system which allows the aggressiveness of the closing wheel to be adjusted. This unit can also be used as a strip till device. It pushes residue away from a defined row while banding fertilizer in a defined area.

The model 3004 is an adventurous design that

owes its existence to our belief that nothing short of perfection is good enough. The way to approach perfection is to constantly evolve. Developmental issues with this unit have been sorted out in the most abusive conditions anywhere (my thanks to the farmers who ran the earliest units- we appreciate your commitment).

The primary justification for this design was the need to be more compact. New John Deere planters often have a limited amount of space available for attachments, yet increasingly farmers desire both row cleaning and the ability to deposit substantial amounts of fertilizer with the planter. The 1770NT is an excellent planter to use with this unit.

The next reason for the 3004 is the need to have more upper blade travel on large planters. For example, on the 60 foot Kinze 3700 (a common application), you have essentially two 30 foot rigid planters. This is actually good because it gives the planter more frame weight to get the units into the ground. Eventually one will hit a large rock right in the middle of the wing which causes half of the planter to be lifted on a single fertilizer opener. Making the unit robust is the first course of action. However, in practice it is almost impossible to make a unit small enough that can handle the extreme impact loading. The concept of the 3004 is to give the unit absolutely the maximum amount of travel permitted by the clearance with the row unit then let the physical strength of the skeleton do the rest of the work.

The third reason for the 3004 is to improve the row cleaner geometry. It was our desire to be able to get the row cleaner over the centerline of the row unit without having to have the fertilizer so far off center. Now the row cleaner on the 3004 runs at the same set of angles as they do on standard Dawn unit mounted products. This increases the level of performance on 15 and 20 inch rows. The row cleaner has a spring preloading it. This spring can be removed in softer soils. For even less aggressive performance from the row cleaner we recommend using the VariWheel style row cleaner instead of the TW2. This unit will handle very high levels of residue. This is primarily due to the fact that the 3004 incorporates several design themes from the 1572 coulter combination model. The .25 inch thick 18 inch diameter single bevel blade is extremely sharp and will cut through any residue. Once it has cut the residue the single TrashWheel is positioned to grab it and pull it to the side.

1201 CurveTineXR Tapered Roller Bearing For 1700 Series JD and Most White 1301 CurveTineXR Tapered Roller Bearing For Kinze

R/L

23

The Dawn CurveTineXR Wheel is the same width as a rubber closing wheel so that it can provide positive seed to soil contact without need of a seed firmer. The curvature of the wheel also allows the teeth to extract themselves from the soil with the tooth perpendicular to the ground. This allows the sidewall to be fractured without the possibility of digging the seed or disturbing the soil once the seed has been placed. For this reason drag chains are not necessary. Consequently the CurveTineXR is much better than alternative solutions in shallow planted crops.

The model 1200 retains the same double tapered roller bearing hub as the Dawn Row Cleaner Attachments. It must be bolted from the interior of the tail-piece. Typically 1700 series Deere planters will use the 1200. Installation is not possible on some planters.

Installation of the model 1300 can be accomplished from the exterior of the row unit tail-piece. The model 1300 is much more convenient on Kinzes. New for Spring 2007, the model 1300 will also use the tapered roller Bearing arrangement. To accomplish this the 1300 gets a more elaborate shaft arrangement that allows the tapered bearings to be bolted from the outside.

7772 Pluribus Strip-Till Unit Dry or Liquid Fertilizer Max depth =<6 in, depending on conditions Weight = 510 lbs/row Speed = 4-9 mph There is no standard definition of what Strip-Till is. One finds everything from deep ripping to side-dressing referred to as Strip-Till. What is known is that there is a problem, with various constraints, and a multitude of possible solutions. The Pluribus Strip-Till unit is positioned to give maximum return on investment to the farmer. It has very low draft loads, which reduces fuel usage and allows wider machines to be utilized. If properly adjusted, it can be run in far wetter soils than any alternative which actively tills the soil. This unit can also handle high levels of residue, allowing it to be run in corn and wheat. One caveat is that the Pluribus unit needs to be adjusted. Fall to spring, soybeans to corn, wet to dry- all of these factors affect the depth that the unit can be run at. There simply is no one depth setting which is appropriate for all conditions. When used properly the Pluribus unit functions astoundingly well. It is really the first tillage device to make the explicit transition to being a fluid dynamic device. The unit produces a turbulent mixing of soil and air which produces a highly friable seed bed. The strips dry very quickly, lending this unit to spring use. It generally makes a nice 3 inch high berm which, when compressed back down by the planter, results in an ideal seedbed. The Pluribus unit enables corn after corn without sacrificing yield, while reducing cost as compared to conventional tillage.
