4 Bell Work / ObjectivesExplain the purpose of tillage systems and equipment used in agriculture.Describe the operating principles of tillage systems and equipment used in agriculture.Describe how tillage equipment is calibrated.Explain how tillage equipment is maintained
6 Interest ApproachLead a discussion with students on what they believe are the purposes or reasons for tillage. Show them various pieces of equipment (next 7 slides) and ask them the function of each piece.
14 Objective #1What is the purpose of tillage systems and equipment used in agriculture?
15 What is tillage? Primary tillage Secondary tillage mechanical, soil stirring actions carried on for the purposes of nurturing cropsPrimary tillagea deep, at least 6”, operation that loosens the soil to reduce soil strength and mix residue and fertilizers into tilled layerSecondary tillageused to kill weeds, cut and cover crop residue, incorporate herbicides and prepare a pulverized seedbed at a depth 5” or less

22 What tillage systems and equipment are used in agriculture? Objective #2What tillage systems and equipment are used in agriculture?
23 Tillage Systems Conservation tillage Conventional tillage field operations required for profitable crop production while minimizing soil erosionleaves at least 30% residue coverConventional tillagesequence of tillage operations traditionally used in your arealeaves less than 15% residue cover
25 Tillage Systems Clean tillage minimum tillage operations which prepares a seedbed having essentially no residue on the surfaceminimum tillageminimum soil manipulation necessary for crop production
26 Tillage Systems reduced tillage mulch-till less intensive and less aggressive than conventionalnumber of operations is decreased or tillage implements require less energymulch-tillconservation tillage that tills the entire soil surfaceat least 30% of residue remaining
27 How is tillage equipment calibrated? Objective #3How is tillage equipment calibrated?
28 Traction, flotation, soil compaction linear force, pull or draft resulting from torque applied to tractor tiresfloatationability of tires to stay on top of the soil surface, avoid slippage which causes compactioncompactioncompression of soil caused by wheel traffic
29 Adding weights to the tractor Additional weights may be required to gain maximum drawbar pull and sufficient tractionadding ballast (weight) to drive wheels and the front end most common way to improve traction
30 Effective ballast Two-wheel drive tractors distribute 25 to 35% of weight on front with 75 to 65% of weight on rearMechanical front wheel drive tractorssplit 35 to 40% on front and 65 to 60% of weight on rear
32 Four-wheel drive tractor weights Standard towed implements51 to 55% on front and 49 to 45% on rearhitch mounted implements55 to 60 % on front and 45 to 40% on reartowed implements causing high down loads on drawbar55 to 65% on front and 45 to 35% on rear
34 Tire tread indications for proper weighting of the tractor Too much weight usedtire tracks are sharp and distinctToo little weight is usedtire marks entirely wiped outProper weightcleats in tire pattern is shifted but tread pattern is visible
35 Balancing tractors Power hop MFWD and 4WD tractors may experience simultaneous loss of traction and a bouncing, pitching ride under high drawbar loads
36 Considerations for tillage implements Properly adjust implements to save time and fuel.Most problems with tillage tools caused by improper adjustment or faulty component.Instructions in owner’s manual should be followed to obtain top performance.Problems can be prevented with simple maintenance at the beginning of the season.
37 Safety Considerations No safety device can replace a careful operator.Match equipment to the tractor.Provide proper tractor ballast and weight split for tractor stability.Match hydraulic connections.Park implement on a firm flat surface.Don’t permit people between tractor and implement.
38 Safety Always lower implement to ground when not in use. If working on equipment in raised position, use blocks so it won’t fall.Use proper size pins and secure with a clips.Never carry riders on tractor or implement.Check wings on equipment before transporting.Transport in narrowest configuration.
40 How is tillage equipment maintained? Objective #4How is tillage equipment maintained?
41 Preventative Maintenance Minimizes the chances for breakage, costly repair bills, and loss of time.All moving parts in contact with other parts require lubrication at point of contact.If dirt is collecting around fittings, clean the area before servicing.
42 Preventative Maintenance Consult operator’s manual for lubricating instructions and location.Proper use of field machinery decreases operating costs.Checking & repairing machinery during off season saves time & money.
43 Simple Maintenance Operations Lubricate according to instructions, clean grease fittings to avoid forcing dirt into bearings.Clean, inspect, and lubricate or repack wheel and coulter bearings.Examine hydraulic hoses, couplings, and cylinders for wear, damage or leaks.Check for loose or missing bolts and nuts.
44 More maintenance tipsReplace worn, dull, or cracked soil engaging components.Check and replace bent or cracked components.Check alignment of soil engaging parts>level the implement side to side and fore and aftmeasure vertical distances to checkCheck safety trips and reset mechanisms.Make certain all tires are inflated properly.
