Maintaining Your Garden Tractor, Engine

SECTION 9: MAINTAINING YOUR GARDEN TRACTOR

NOTE: Refer to Maintenance Chart on page 28 for a reference of recommended maintenance intervals.

WARNING: Before performing any maintenance or repairs, disengage PTO, set parking brake, stop engine and remove key to prevent unintended starting.

Engine

Maintenance, repair, or replacement of the emission control devices and systems, which are being done at the customer’s expense, may be performed by any engine repair establishment or individual. Warranty repairs must be performed by a Toro Dealer.

*Use of synthetic oil having 5W-20 or 5W-30 rating is acceptable, up to 4°C (40°F).

**Synthetic oils will provide better starting in extreme cold below 23°C (-10°F).

The engine-crankcase is filled with 10W-30 ship-awayoil at the factory. This oil may be used for the first 24 hours of engine operation at temperatures between 0°F and 80°F. If temperatures are not within this range, drain the oil from the oil filter and crankcase and replace with new oil.

The engine oil must be drained and replaced with new oil after the initial 24 hours of engine operation and every 50 hours thereafter. Refer to the Oil Viscosity Chart to determine the proper oil type.

NOTE: To aid starting, the selection of crankcase oil should be based on the lowest anticipated temperatures prior to the next scheduled oil change.

Checking the Oil Level

It is important to check the oil level at least every four hours of operation. Regular checking during the first 24

IMPORTANT: Never operate the engine with the oil level below the ADD mark or above the FULL mark on the dipstick.

•After checking the oil lev- el (and adding oil, if nec- essary), reinstall the oil fill cap/dipstick by insert- ing it into the oil fill tube.

Adding Oil

If, after checking the oil level, you find the dipstick reads ADD, proceed as follows.

hours of operation is especially important. Check the oil level before each use as follows:

•Allow the engine a few minutes to rest after opera- tion. This will give the oil time to drain into the crank- case sump and result in a more accurate dipstick reading.

•Clean the area around the oil fill cap/dipstick to pre- vent debris from entering the crankcase.

•Remove the oil fill cap/dipstick by twisting it out of the oil fill tube.

•Wipe the dipstick clean before inserting it all the way back into the oil fill tube. Withdraw the dipstick to check the oil level. Refer to figure at right.

•Always keep the oil level at or near the FULL mark on the dipstick. If the oil is low, add oil of the proper type up to the FULL mark. Always re-check the oil level with the dipstick before adding more oil.

•Place the tractor on a level surface and engage the parking brake. Stop the tractor engine and remove the ignition key.

•Clean the area around the oil fill cap and fill tube to prevent debris from entering the crankcase.

•Remove the oil fill cap/dipstick from the oil fill tube and SLOWLY pour oil into the oil fill tube. Do NOT pour more than 6 oz. of oil at a time without first stopping and re-checking the oil level.

•Fill the crankcase until the oil level reaches the full (F) mark on the dipstick. See Figure above. Refer to the oil viscosity chart earlier in this section for information regarding the proper type of oil to add to the crankcase.

IMPORTANT: The engine (with oil filter) has a capacity of

1.7liters (57.5 oz.). Never overfill the engine crankcase.
