How to Service a Case 446 Garden Tractor
The J.I. Case Company started building equipment used on farms in 1842. The company purchased Colt Manufacturing in 1964 and began manufacturing tractors. Mowing decks, tillers and snow plows were just a few of the optional attachments available for a Case 446 Garden Tractor. The following maintenance steps will assure many years of service for the engine of the tractor.
Items Needed:
- Air filter
- Air pressure gauge
- Crescent wrench
- Flat surface
- Fuel filter
- Oil
- Oil filter
- Pan to catch the oil
- Work gloves
- Purchase the correct air filter, fuel filter, oil filter and oil as specified for the tractor.
- Park the Case 446 Garden Tractor on a flat surface, and allow the engine to cool.
- Put work gloves on hands for safety and protection.
- Lift the compartment cover for the air filter, dispose of the old air filter and replace with the new air filter.
- Examine the engine for the oil plug to the left corner of the engine block, which may be a square spout looking drain or a hex-shaped drain.
- Rest the oil pan to catch the oil under the plug. Remove the plug using a crescent wrench to allow the oil to fully drain and then replace the plug.
- Locate the oil filter near the engine block. Lift and properly dispose of the old oil filter.
- Seat the new oil filter firmly in position.
- Open the cap, and dispense the new oil into the engine.
- Check the oil level sporadically with a dipstick to estimate the amount of oil needed and to prevent over filling.
- Replace the cap and properly dispose of the empty oil cans.
- Find the fuel filter attached to the fuel line under the tractor. Remove the old filter from the fuel line, and secure the newly purchased filter in its place.
- Use the air pressure gauge to check the air in the tires and fill the air to the level designated in the owner’s manual.
