- Tractor Maintenance Schedule by Hour Interval
Tractors are serviced by the hour meter, not the calendar. Here is how to turn the manual's service chart into a routine you will actually follow. - Daily Tractor Inspection Checklist
Five minutes with a flashlight before you climb on can save a day in the field. This is a simple walk-around you can run before every shift. - Pre-Season Tractor Maintenance
A tractor that sat all winter should not go straight into a hay field. A methodical spring check keeps the first big job from turning into a... - Post-Season Tractor Storage Checklist
How you put a tractor away decides how it starts next spring. Work through this list while the season's problems are still fresh in your mind. - Changing Engine Oil in a Tractor
An oil change is one of the best jobs to do yourself on a tractor, as long as you use the right oil, set up safely and dispose of the old oil... - Tractor Oil Filters: When and How to Replace
The oil filter is a cheap part doing an expensive job. Replace it on schedule, match it to your engine, and install it carefully. - Air Filter Maintenance for Tractors
A tractor breathes through its air cleaner. In a dusty field, that filter is the only thing between the engine and a very expensive wear problem. - Fuel Filter Replacement Basics
Clean fuel keeps a diesel running smoothly. Changing the fuel filter is a manageable owner job if you take care of cleanliness and air in the system. - Coolant Maintenance for Tractors
Coolant does more than fight overheating. It also protects the engine from rust and freezing, and it wears out with time. - Radiator Cleaning and Overheating Prevention
Most tractor overheating starts with something simple: a radiator clogged with chaff, dust and seed. Cleaning it takes minutes and prevents a lot of... - Hydraulic Fluid Checks and Changes
The hydraulic system lifts your loader, raises the three-point hitch and steers many tractors. Clean fluid at the right level keeps all of it working. - Hydraulic Hose Inspection and Replacement
A failed hydraulic hose can drop a loader, spray hot oil and injure a person. Regular inspection catches most failures before they happen. - Transmission Fluid Maintenance
Transmission fluid lubricates gears, cools them and often works the clutches and brakes too. Letting it go too long is an expensive mistake. - Gearbox Oil Changes
Besides the engine and transmission, a tractor and its implements hide several gearboxes. Each one has its own oil, and each is easy to forget. - Greasing a Tractor: Points You Should Not Miss
Grease is the cheapest protection on the farm. Missing one fitting can ruin a pin or a bearing, so know where all of them are. - Tractor Battery Maintenance
Most no-start calls on a tractor come down to the battery or its connections. A few minutes of care a few times a year prevents nearly all of them. - Battery Testing and Replacement
A battery that spins the engine slowly is not always finished. Test it first, then replace it only if it fails. - Alternator and Charging System Troubleshooting
When the battery keeps going flat, the problem is often the charging system. A step-by-step look usually shows where to stop and where to call for... - Starter Problems: Diagnosis and Fixes
A tractor that will not crank can be a dead battery, a bad connection, a safety switch or the starter itself. Work through them in order. - Tractor Wiring Basics
Tractor wiring is simpler than it looks. Understanding circuits, grounds and connections helps you find faults without guessing. - Fuse and Relay Troubleshooting
A blown fuse is the circuit telling you something. Replacing it is easy, but finding why it blew is the real job. - Headlight and Work Light Repair
A tractor with weak lights is a hazard at dusk and on the road. Most light problems are bulbs, grounds or corroded connectors, all of which you can... - Tractor Tire Pressure and Wear
Tires are the only part of the tractor that touches the ground. Pressure and condition affect traction, fuel use, compaction and safety. - Fixing a Flat Tractor Tire
A flat out in the field is a safety job before it is a repair job. Block the tractor, support it properly and decide what you can handle. - Tire Ballast Maintenance
Ballast gives a tractor weight for traction and balance. It needs checking too, because weight is also a safety matter. - Wheel Bearing Inspection
Wheel bearings carry the whole weight of the tractor and everything hanging off it, yet most owners never look at them until something wobbles. A... - Brake Maintenance for Tractors
Tractor brakes get used hard on slopes, with loaders and when towing, and they are one of the few systems where a wrong guess can hurt someone.... - Clutch Adjustment and Replacement
A clutch wears a little every time you use it, and the way you use your tractor decides how fast. Understanding free play and the early signs can... - PTO Clutch Problems

Steering problems on a tractor are safety problems. Learn what each symptom tends to point to, and know where owner checks end and a mechanic begins. - Power Steering Fluid Maintenance
Power steering fluid is easy to ignore because the system seems to run itself. A little attention to level, type and cleanliness keeps the pump and... - Cooling Fan and Belt Replacement
The fan and its belt keep air moving through the radiator, and a worn belt or damaged fan can lead to overheating long before a gauge shows trouble.... - Serpentine Belt Maintenance
One long, flat belt often drives the alternator, water pump and fan on a modern tractor, so its health affects charging and cooling at the same time.... - Water Pump Failure Signs
The water pump circulates coolant through the engine and radiator. When it begins to fail, the signs are usually quiet and easy to dismiss until the... - Thermostat Replacement
A thermostat is a small, inexpensive part that controls how hot your engine runs. When it fails, the result can be an engine that never warms up or... - Diesel Fuel System Basics
A diesel engine lights its fuel by compression, with no spark plugs involved, so a clean fuel supply matters more than most owners realize. Knowing... - Bleeding a Diesel Fuel System
Air in the fuel lines is a common reason a diesel will crank but not start. Bleeding the low-pressure side is a standard owner task on many tractors,... - Injector Problems and Symptoms
Injectors turn pressurized diesel into a fine spray inside each cylinder. When one fails, the engine tells you in smoke, noise, rough running or lost... - Glow Plug Troubleshooting
A diesel starts by compression, but in cold weather that heat is not always enough. Glow plugs add warmth to the combustion chamber, and a weak set... - Cold-Starting a Diesel Tractor
