Riding Mower and Tractor: Leaking oil or gas

Check the oil level when the engine leaks oil. Drain oil to the full mark on the dipstick if you find the engine overfilled. Engine problems can cause oil or gas leaks. If you notice stains on the pavement or garage floor, investigate the source of the leaking fluid. For an oil stain, check the head gasket and the sump gasket. A loose or cracked fuel line can cause gasoline to leak from the tractor. Move the tractor to a well-ventilated area and drain the fuel out of the tank if you discover a fuel leak. Find and replace the leaking component.

These repairs may help solve your Riding Mower and Tractor problem:

Tune up the riding mower engine

Fuel filter

The engine tune-up includes routine maintenance for a riding lawn mower or tractor. This tune-up includes replacing the engine oil, oil filter, air filter, fuel filter and spark plug. The tune-up also includes checking the ignition, carburetor, battery, throttle and choke controls, as well as cleaning the engine cooling fins.

Replace the riding mower carburetor assembly

Carburetor

If the engine on your riding mower or lawn tractor is running roughly or only runs when the choke is partly on, you might need to replace the carburetor. The carburetor mixes gas with air before the fuel goes into the cylinder. If the gas/air mix isn't balanced, the engine won't have peak performance.

Rebuild the riding mower engine carburetor

Carburetor

The carburetor mixes fuel with air to create a combustible mixture that enters the engine cylinder and ignites to drive the piston. Impurities in gasoline can clog the carburetor. Seals and gaskets in the carburetor eventually wear out. Use a carburetor rebuild kit to refurbish a clogged or leaking carburetor.

Replace the riding mower head gasket

Head gasket

Replacing the head gasket, which requires a torque wrench, involves removing the cylinder head and cleaning the mating surfaces. A symptom of a defective head gasket is low compression.
