Farmstead Planning

3

Good Planning Allows…. • Improved efficiency, higher capacity, better

labor use, more convenience, and/or more profit over existing system

• Arranging facilities to leave space for future changes

• Unobstructed flow of traffic to various farm activities

• Flexibility to adapt facilities for different uses • Separating family from farm safety hazards

4

Steps to a Good Plan 1. Identify your farm & family goals 2. Sketch to scale the existing facilities 3. Appraise old facilities 4. Sketch your ideal plan 5. Develop budgets to evaluate return on investment 6. Make wise compromises 7. Test flow patterns for restrictions

5

1. Identify Goals

• Expanding an enterprise to increase income • Adding facilities to improve labor efficiency • Developing a new enterprise • Increasing value with minimum investment • Improving family living environment • Separating family living from farm enterprise

6

Land Use • How much land is needed? • Fencing • Gardening • Livestock • Crop production • Wildlife/hunting • Recreation • Income

7

Maps and Photos

Obtain: • Aerial photos and

topographical maps • Soils maps • Crop and conservation

records

8

Resource Agencies

• Natural Resources Conservation Service (NRCS) • Farm Service Agency (FSA) • Soil and Water Conservation Districts (SWCD) • MU Extension • State and local government

2. Sketch to Scale….

• Slopes • Building locations • Utilities (above &

below ground) • Roads & easements • Other physical features

Graph paper: incompetech.com/graphpaper/multiwidth/

11

Slope Measurement by Elevation Change

Slope in % = (vertical / horizontal) x 100

Two types of instruments • Builder’s level + measuring rod • Line level + string + tape measure + stake

12

Slope Measurement by Direct Reading

Two types of instruments • Clinometer (Abney level) • “Smart” level (electronic)

13

More Planning Factors

• Power lines and utilities (call before you dig) https://www.mo1call.com

• Hazards and potential hazards • Nearby land use • Regulations or zoning in your area • Flood-prone areas

14

Site Selection • Geology determines location in the Ozarks

– “Slight”, “Moderate” & “Severe” ratings

• Many current sites limit future growth – 4 acres per 100 dairy cows for facilities – 1 acre per 100 dairy cows for lagoon area – 0.2 to 1 acre per cow for spreading manure

• Speed of rural residential growth • Production facility size dictates farm/family

association – Large operations = separate farm from home – Smaller operations = “zone” plan around home

3. Appraise Old Facilities • Usefulness for a given purpose • Adaptability for new purpose • Condition

– Replace if over 50% of retrofit cost

• Location – Gates, tight corners & wrong locations waste steps & time

• Maintenance vs. elimination over time – 2/3 of working time on livestock farms is spent

in & around the buildings 22

Appraise Old Facilities

Older buildings and tight turning space for larger trucks 23

Drainage • Ideal land slope = 2-6% (1/4”-3/4” per ft.) • South slope best for natural drying & livestock

feeding, then East, then N or W • Ozarks historically has 41”- 42” of rainfall &

36” of evaporation annually – Dirt lot runoff = 17,500 gal. per 1000 sq.ft. roof – Concrete lot = 26,000 gal. per 1000 sq.ft. roof

• Control surface runoff with diversions • Control subsurface water with curtain drains • Odors in still air move downhill like water

4. Sketch Your Ideal Plan • Check DNR & zoning regs. & building codes • Visit other farms for ideas • Planning consultants charge up to 3-4% of

facility construction cost • Observe required separation distances • Mistakes on graph paper or computer are less

costly & easier to change • Check proposals with stakes & twine • Dream a little! 34

Styles of buildings

47

Buildings • Design: 90+ MPH winds, 25+ psf roof load

– Embed posts 4+ ft. deep, 12+ ft. high walls

• Raise floors 8”-12” above outside grade • Space at least 50 ft. apart for fire protection • Clear-span construction

preferred for flexibility • Steel cheaper than

wood over 40 ft. wide • Take advantage of solar

– E-W orientation for buildings – N-S for feed bunks, high tunnels

5. Budget/Evaluate R.O.I.

• “Partial budgets” provide estimates of costs & return on investment

• Get help & costs from – FINPACK software through Extension – Midwest Plan Service (plans) – Building contractors – Farmers who built similar facilities

66

6. Make Wise Compromises • Does it make good economic sense? • What is payback time of improvements? • Replace older buildings in phases • Don’t let sentimental value of old buildings limit

proper placement of new facilities • Bury utilities now that can be used later • Strive for intensive use of costly facilities • Size dictates management (people vs. animals) • Consider resale value of improvements 67

7. Test Flow Patterns • People

– Safety from livestock & vehicles

• Vehicles & machinery – Minimize gates & mixing with livestock

• Feed – All-weather driveway access

• Manure – Visibility to roads, odor impact, enough acres

• Livestock – Access to water, restrict visitors 68

Avoiding DNR Visits • Keep farmstead neat = positive public image • Plant grass/tree buffers to filter & hide • Fence & rotate pastures to reduce animal damage • Inform neighbors when spreading manure • Roof animal traffic areas • Gutter roof, lot & driveway clean water • Budget funds & time for the waste system • Make improvements compatible with DNR

regulations 69

Farm Shops

70

A Well-Planned Farm Shop…. • is energy-efficient • is a place to assemble, service, repair, adjust &

modify machinery and equipment • is a place to work on farm, family and recreational

vehicles and hobby projects • encourages preventative maintenance of equipment • is a headquarters for farm management, employees

and daily callers

What’s the price of a day lost to a breakdown during planting or harvest that could have been fixed in a good shop?

71

Top 10 List of Shop “Musts” by a poll of farmers

• Size • Ventilation • Lighting • Heating • Wall covering • Drainage

• Water • Office space • Electrical outlets • Pneumatic lines • Extinguishers • Tools and accessories

72

Initial Planning 1

• Warm-weather or year-round shop? – How handy are you?

• Make it big enough for equipment 5-10 years from now – Build length with expansion in mind – Research how to hold costs down

• Locate shop within 150 feet of house • Storage for service manuals & records • Energy-efficiency

– Lighting, heating, insulation – Insulate shop like you would your house

73

Initial Planning 2

• Think about grade before construction – Will you have floor heat, water drains? – Floors at least 12” above existing grade; slope 5% away

• Shop size – Size door with at least 2 ft. of side clearance and

1 ft. of head clearance for largest equipment – Install 36” service door to save energy – Add room for work benches, welders, tool caddies and

walking room around machinery

• Utilities – Telephone, running water, rest room, future office? – Run electrical conduit for future needs 74

Basic Farm Shop Floor Plan

76

40’ x 48” Farm Shop Floor Plan

77

Concrete Floor 1

• A necessity – Durable and easier to clean – Easier to find dropped parts – Easy to roll shop tools around – Reduces dust problems

• Subgrade preparation – Remove all sod, vegetation, manure, etc. – Compact fill soil in moist 4”-6” lifts, or

allow soil to settle 6-12 months before building

15-20 psi 35-45 psi

Rubber-tire scraper 40-60 psi Sheepsfoot roller > 300 psi Woman in high heels > 860 psi

79

Concrete Floor 2

• Use 6-mil plastic over soil to stop moisture migration – Add 2” rigid foam over plastic if heating floor – Install electrical conduit for future needs

• Add a 4” thick compacted gravel or sand base • Slope the concrete floor 1” per 10 ft. toward a

drain or the entry door • Use 3,500 psi concrete, add 6% air-entrainment in

outdoor slabs • Thicken outer 16” of slab to reinforce edges

80

8" 400%

81

Ordering Ready-Mix Concrete • What you want concrete for • How much you need (in cubic yards) • Strength of concrete you need (in psi)

– Price is based on compressive strength

• Durability: – Water:cement ratio, OR – Gallons of water per bag of cement

• Air entrainment (in percent) • Slump (in inches) • Other needed properties 82

Lighting 1

• General indoor lighting (20 foot-candles at floor level) – ½ watt fluorescent per sq.ft. floor area, or

2 watts incandescent per sq.ft. floor area – Equals 1 double-tube, T-5 or T-8 4-ft. fluorescent fixture at

8 ft. height per 80-100 square feet of floor area – Light-colored ceilings and upper walls help

• Indoor task lighting – Use double-tube, 4-ft. fluorescent fixtures mounted 4 ft.

above the work bench and positioned toward the front half

• Use incandescent or LED lamps over rotating tools like grinding wheels to avoid the strobe effect

83

Lighting 2

• General outdoor lighting – Use 200-400 watt high-pressure sodium or metal halide

lamps, mounted at a 15-25 foot height, with photocell control

– Space up to 125 feet apart for best lighting conditions – Place a 150-watt spotlight, with motion sensor activation,

on one or both sides of the entrance door instead of over the door, to keep out flying insects

84

Electrical 1

• Minimum 200-amp, 240-volt service – Locate near service door for emergency shut-off

• Outlets – Locate max. 10 ft. apart around walls at 4 ft. height – One 20-amp duplex outlet for each 4 ft. of work bench;

put under front edge to keep cords off the bench – One for each permanent motor-driven tool that is

½ HP or less

• Use GFCI/AFCI outlets in damp & outdoor locations

85

Electrical 2

• Individual branch circuits must be used for outlets serving motors larger than 1/2 HP – Plan for one circuit to serve no more than three 1/3 HP

motors, two 1/2 HP motors, or one 1 HP motor or larger

• Use at least a 50-amp, 240-volt, 2-wire with ground circuit and outlet for a welder – Locate it just inside the door, OR – Add a second weatherproof outlet

on an outdoor yard pole, so larger machinery can be repaired outside

86

Insulation • Warm-weather shop

– R-5 in ceiling or roof to relieve summer heat, condensation

• Year-round shop – R-18 sidewalls – R-30 to R-49 ceiling – R-10 doors – R-10 under heated concrete floors,

R-5 if unheated

87

Ventilation • Wall-mounted exhaust fan

– Allow 1,000-2,000 CFM airflow per welder

• Vent engine exhaust outdoors with rubber hose or metal ducting – Provide 100 CFM airflow per vehicle in shop

Photo credit: http://www.sentryair.com

88

Wall Covering • Fire-resistant wall board for insulated shops • Durability

– 5/8” plywood or 3/4” particleboard around welding area and workbenches

• Build firewall between shop and machinery storage if both are under same roof

• Perforated metal on upper walls good for sound control

89

Heating Options 1

• Temperature – Occupied = 45-60°F – Not in use = 40-45°F

• Radiant (infrared) heaters – Ceiling-mounted or portable floor-type – Provide the most instant heat – Are easily changed and relatively safe – Makes a room at 60°F feel almost as comfortable as one at

70°F degrees with forced air heat – Raising heater height increases area heated – Size at 40 BTUs (British Thermal Units) per hour,

per square foot of floor area. 90

Heating Options 2

• Gas-fired or waste-oil forced-air furnaces – Good for heating large areas – Ceiling-mounted units help keep

hot air from stagnating near the ceiling – Waste oil units are economical to operate

• Provide a quick heat source • Most will burn No. 1 or No. 2 fuel oil as well as waste oil

– Size at 50 BTUs per hour, per square foot of floor area. – Use a minimum of 70,000 BTUs per hour if the shop is

fan-vented at 1,000 CFM to remove welding fumes, engine exhaust or dust.

91

Heating Options 3

• In-floor heaters – The most expensive to install – Electric resistance cable or hot water pipes

buried in concrete over rigid foam insulation – Make the floor warm to work on, are quiet,

and reduce dust circulation – Takes the system several hours to warm the shop

to a comfortable temperature – Work best in conjunction with a ceiling-mounted

forced-air furnace near the door – Size electric heat cables at 15 watts per square foot – Size water pipes at 50 BTUs per square foot in the

bench area and 4 feet out into the service area – Keep max. floor temperature < 80°F for foot comfort

92

Heating Options 4

• Unvented fuel-fired space heater – Offers relatively inexpensive supplemental heat – Must have outside ventilation of 4 CFM per 1000 BTUs

per hour of heater capacity to prevent CO buildup

• Electric resistance heaters – 100% efficient – Use several smaller units instead of one large unit,

due to their high operating expense • Solar

– At the mercy of Mother Nature – Warm air can be directed at ceiling or floor

93

• Are the back tires capable of supporting the load?

• Is front ballast adequate? – Safety of keeping the front of the tractor on

the ground 113

Hydraulic System

• Open-center – Fixed displacement pump – Typically found on older and smaller tractors

• Closed-center – Variable displacement pump – Typically found on larger newer tractors

• Number of remotes will vary • Pump capacity

114

PTO • Three Sizes

– 540 RPM 6 spline – 1000 RPM 21 spline – 1000 RPM 20 spline

• Some models support both • Two drive types

– Transmission driven – Independent

115

127

Tractor Buying

• Budget • New or Used (Used based on hours of use) • Age (50+ year old tractors can still have some use) • Size needed • Reputation/quality of models • Hours of use per year • Uses • Ease of use

128

New or Used • Advantages of new

– Warranty – Ease of operation with

newer technology – Safety

• Disadvantages of new – Initial price – Depreciation – Do the hours justify a

new tractor?

129

New or Used • Advantages of Used

– Lower initial price – Price will match use

• Disadvantage of Used – Possible higher repair

costs – Possibly not as easy to

operate – Operator comfort

130

Size Needed

• Uses – Loader work – Tillage – Mowing – Baling

• How much time you have – Theoretical field capacity in acres/hour

= Speed x Width x Efficiency / 8.25 131

Loader Work

• What will it be used for? • Is FWD needed? • Type of transmission • Weight distribution

132

Loader Tractor • FWA with shuttle type

shift – Provides better pulling

power – Handles front end weight

better – Manages muddy

conditions better – Higher maintenance

133

Loader Tractor • Rear weight distribution

– Steel rear weights – Fluid in rear tires

• Typically water with calcium chloride (ex. 1000 lbs./tire)

• May or may not be needed in tractors with FWA

134

Loader Tractor • Transmission

– Older style – Newer style with shuttle

Ballast and Tire Pressure

148

Before you buy • Learn machine history

– Where it came from – What it was used for – Maintenance records

(professional / self-serve) – Known issues – Accident history – Clear ownership

149

Correct Tires

• Bar tire – Tillage – Dirt moving – Brush hogging – Snow removal

• Diamond tread – Turf applications

150

Hitch Compatibility • Drawbar

– Is the implement pulling level?

– Is the drawbar and hitch pin strong enough?

• 3 pt. hitch – Compatible size

Mounted

Semi Mounted Pull Type

151

PTO Compatibility

• 540 and 1000 rpm shafts

• Smaller/lighter implements will be 540

• Larger implements will be 1000

• Some implements can be modified to use both

152

Hydraulics

• Compatibility • Number of outlets

– 1-4 – Older tractors had

different ends by manufacturer

• Capacity – GPM needed

• What you are using – Cylinders, motor, etc. 153

What to look for -- Tractors • Fluids

– Leaks – Smell – Appearance – Crackle test: detects

water in oil up to 500 ppm (0.05%) depending on type of oil

154

What to look for -- Tractors

• Belts: cracks, wear • Hoses: cracks, leaks, rub

locations • Clutch: engagement,

travel, smoothness • Gears: engagement,

disengagement, excessive movement, all present?

• Live PTO 155

What to look for -- Tractors

• Structure: noticeable weld/repairs

• Battery: age, corrosion • Wheels: noticeable

bend/wobble, “test drive”, fluid/ballast? (if yes, rim rust?)

• Tires: cracks, cuts, wear, common size?

156

What to look for -- Tractors

• Accessories included: or previous uses (dairy farms and/or loader tractors commonly have increased wear)

• Zerk fittings: do they appear to have been used?

• Safety equipment: ROPS, seatbelt, SMV, lights, guards

• Cab: do the instruments work?, A/c should be about 40⁰F
