6. 

Reinstall the oil drain plug securely. Be careful not to 

overtighten.

4. 

Refill the engine with new motor oil as instructed in the 

Engine Owner’s Manual packed with your unit.

Refer to the Engine Owner’s Manual packed with 

your unit for information regarding the quantity and proper 

viscosity of motor oil.

To complete an oil change, proceed as follows:
1. 

Run the engine for a few minutes to allow the oil in the 

crankcase to warm up. Warm oil will flow more freely and 

carry away more of the engine sediment which may have 

settled at the bottom of the crankcase. Use care to avoid 

burns from hot oil.

2. 

Open the tractor’s hood and locate the oil drain port on the 

right side of the engine.

3. 

Pop open the protective cap on the end of the oil drain 

valve to expose the drain port. Figure 6-2.

4. 

Remove the oil fill cap/ dipstick from the oil fill tube.

5. 

Push the oil drain hose (packed with this manual) onto the 

oil drain port. Route the opposite end of the hose into an 

appropriate oil collection container with at least a 2.5 quart 

capacity, to collect the used oil.

6. 

Rotate the drain valve counter-clockwise and release to 

drain the oil. See Figure 6-2. 

7. 

After the oil has finished draining, push the end of the oil 

drain valve back in, until the tabs click into place. Re-cap 

the end of the oil drain valve to keep debris from entering 

the drain port.

Before performing any maintenance or 

repairs, disengage PTO, move shift lever into neutral 

position, set parking brake, stop engine and remove 

key to prevent unintended starting.

Refer to the Engine Owner’s Manual for engine maintenance 

instructions.
Check engine oil level before each use as instructed in the Engine 

Owner’s Manual packed with your unit. Follow the instructions 

carefully.

For draining oil from the engine’s crankcase, a plastic oil drain 

sleeve is packed with this Operator’s Manual. To drain the oil, 

proceed as follows:
1. 

Run the engine for a few minutes to allow the oil in the 

crankcase to warm up. Warm oil will flow more freely and 

carry away more of the engine sediment which may have 

settled at the bottom of the crankcase. Use care to avoid 

burns from hot oil.

2. 

Open the tractor’s hood and locate the oil drain port on the 

right side of the engine and the oil fill cap on the topside of 

the engine.

3. 

Unscrew the oil fill cap and remove the dipstick from the oil fill 

tube.

4. 

Snap the small end of oil drain sleeve onto the space 

provide around the oil drain plug. See Figure 6-1.

5. 

Remove drain plug and drain oil into a suitable container 

with a capacity of no less than 64 oz.
