Why does lubrication matter so much?
Moving metal parts wear each other down without a film of lubricant between them. Dirt, heat and water speed up the wear. A dry bearing can fail in a single season, and the repair costs far more than a tube of grease. Think of lubrication as insurance you pay in small, frequent amounts.
Each machine has its own needs. Your operator's manual lists lubricant types, grease points and intervals. Follow it rather than relying on habit or neighbors' advice.
Tape a card to the machine with the points and intervals, so you do not depend on memory in a busy week.
- Cheaper than repair
- Easy to skip when busy
- Follow the manual
- Track hours or dates
What is the difference between grease and oil?
Grease is oil thickened to stay in place. It suits bearings, pins and bushings that are hard to reach or that move slowly. Oil flows and cools, so it suits engines, gearboxes, hydraulic systems and chains. In very cold or hot conditions the manual may call for a different grade, so check seasonal guidance.
Mixing different greases can cause breakdown, because some types are not compatible. Use what the manual calls for, and wipe old grease off the fitting before adding new.
If you are unsure, ask the dealer's parts counter to match your manual to the right products.
- Grease for pins, bushings and slow bearings
- Oil for engines, gearboxes and chains
- Do not mix grease types unless the maker allows it
- Match the grade to temperature and load
Where are the grease points and how often should you use them?
Look for small fittings called zerks on pivot points, wheel hubs, drive shafts, steering parts and implement hitches. The manual shows each one. Hard-working implements, such as balers and loaders, often need grease every day or every few hours of use. Some sealed bearings are marked as maintenance free, so do not add grease where the maker says not to.
Use a hand or air-powered grease gun and add only a few pumps. Too much grease can blow out seals. Wipe off excess so dirt does not stick.
Keep a rag in your back pocket and make fittings part of every refueling stop.
- Wipe the fitting first
- A few pumps at a time
- Watch for seal blowout
- Wipe off the excess
How do you avoid contamination?
Wipe the fitting clean before attaching the gun. Keep grease tubes and oil containers capped and label them. A speck of grit in a bearing acts like sandpaper.
Store lubricants in a clean, dry spot out of sun and away from fuel and flame. Never pour used oil on the ground or drain it into a ditch. Ask your county solid waste office about disposal.
Disposable gloves keep grease off your hands and your steering wheel.
- Clean fittings and tools
- Cap containers
- Store out of sun
- Dispose of used oil properly
How do you handle gearboxes, chains and driveshafts?
Check gearbox oil levels through the sight glass or plug, with the machine level. Chains need a light oil or a chain lubricant meant for them, applied as the manual states. Driveshaft slip joints and universal joints need grease as well. Keep guards and shields in place after you finish, since lubrication jobs are when people remove them and forget.
Turn off and block any machine before lubricating moving parts. Never reach into a running implement, and keep loose clothing away.
Wear eye protection when using a pressurized grease gun or air tool.
- Level and check plugs on gearboxes
- Lubricate chains per the manual
- Grease universal joints and slip joints
- Shut off and block before reaching in
How do you keep a lubrication schedule?
Make a chart for each machine listing points, lubricant and interval, and tape a copy near the machine. Note the date and hours when you grease. An annual walk-through with the manual catches fittings you have never touched. Share the chart with anyone else who uses the machine so nothing is greased twice or missed.
Check for dry, noisy or hot bearings during use. A change in sound or heat is a warning. Stop and check before it gets worse.
Keep spare fittings and caps in your kit, since a missing fitting means no lubrication at that point.
- Chart per machine
- Note dates and hours
- Listen for noises
- Check for hot bearings
Key takeaways
- Follow each manual for grease points, lubricant types and intervals.
- Do not mix grease types unless allowed.
- Clean fittings first and add only a few pumps at a time.
- Keep a simple chart and note hours or dates.
