Tillage & Soil Prep EquipmentTillage Equipment Maintenance
Tillage tools work in dirt, rocks and moisture, so they wear fast. A simple routine of looking, greasing and fixing small problems keeps them running through the season.
Key points
- Look over the machine before every use.
- Grease on schedule with clean fittings and the right grease.
- Replace worn parts before they damage shanks or hubs.
- Never check hydraulic leaks with your hands.
- Use blocks and stands, not hydraulics alone, when working underneath.
What should you check before every use?
Walk around the machine before you hitch up. Look for loose or missing bolts, cracked welds, bent frames, worn or broken shanks, discs, sweeps and tines, and anything that looks out of place. Check the hitch pins, safety chain and any locking devices.
Check tires and wheels on wheeled implements, plus any hydraulic hoses and fittings. Inspect for rubbing, cracking or weeping. Look at the lights and slow-moving-vehicle emblem if you will use public roads.
- Bolts, pins and clips all present and tight
- Welds and frame free of cracks
- Wear parts not worn past the manual's limits
- Hoses and fittings dry and undamaged
How do you grease and lubricate tillage tools?
Greasing is the cheapest maintenance there is. Bearings on discs, gangs, wheels and pivot points need grease on a schedule that depends on use and conditions. Your operator's manual gives the points and the recommended grease type.
Wipe fittings clean before greasing so you do not push grit into the bearing. Pump until fresh grease just appears at the seal if the manual allows. Over-greasing can blow seals, so follow the manual, and replace any fitting that does not take grease.
Do not skip wipes and cleanup. Mud caked on the lubrication points hides leaks and cracks, and it hides the very wear you are trying to find. A quick wash and a dry-off before a seasonal inspection pays for itself in what you notice.
How do you inspect wear parts?
Shovels, sweeps, points, discs and blades wear with use and soil type. Sandy or abrasive soils wear them faster. Check them against wear guidelines from the manufacturer and replace them before they wear into the shank or hub.
Worn parts cost you more than the replacement does. They need more pulling power, burn more fuel and do a poorer job of cutting and covering. Keep spares on the shelf before the busy season.
What about hydraulics on tillage tools?
Many tillage tools use hydraulic cylinders for lift, folding and depth control. Check hoses, fittings and cylinders for leaks and damage. Never check for a leak with your hand. High-pressure fluid can inject through skin and cause serious injury, so use a piece of cardboard or follow the manufacturer's method, and get medical help immediately if fluid pierces the skin.
For leaking cylinders, burst hoses or fold system problems, call a qualified mechanic or the dealer service department. Always use the hydraulic fluid and hose type the manufacturer specifies, and lower the implement fully before working near it.
Check the hitch and any lift linkage too, because worn pins and bushings let the implement wander and can add stress to a frame. Three-point hitch categories 1, 2, 3 and 4 exist for a reason, so confirm the implement and tractor categories match.
What seasonal maintenance matters most?
Do a full inspection at the end of the season and again before the next. Clean off dirt and residue, then inspect, repair and repaint worn spots to slow rust. Make a list of parts to replace and order them when you have time.
Tighten bolts to the torque the manual specifies, not by guess. A loose bolt on a shank or gang can fail and cause damage far worse than the bolt itself. If you cannot find the figure, ask the dealer.
How should you block and support the implement?
Never work under a raised implement held only by hydraulics. Use rated stands or blocks set on firm ground, lower the implement to the ground if you can and shut off the tractor before reaching in. Folding wings can drop without warning.
Keep shields in place and never remove safety devices to make a job easier. If a pin, lock or guard is damaged, replace it with an approved part before work resumes.
When is it not worth doing yourself?
Greasing, bolt checks and wear part swaps are fine for most owners with the manual and basic tools. Structural welding, hydraulic repair, gearbox work and anything involving bent frames deserve a qualified shop.
A badly bent frame or cracked beam can fail without warning. Pay for a professional look if you are not sure, and keep service notes so you know what was done and when.
