Checking the Engine Oil
Only use high quality detergent oil rated with API service classification SF, SG,
SH, or SJ. Select the oil's SAE viscosity grade according to the expected operating
temperature. Follow the chart below. Although multi-viscosity oils (5W20, 10W30,
etc.) improve starting in cold weather, they will result in increased oil consumption
when used above 32°F. Check your engine oil level more frequently to avoid possible
engine damage from running low on oil.

Oil Viscosity Chart
To check the engine oil, proceed as follows:
•
Ensure that the tractor is on a level surface.
•
Clean the oil fill area of any debris.
1.
Remove the dipstick and wipe with a clean cloth.
2.
Insert and tighten dipstick.
3.
Remove the dipstick and check the oil level. It should be at the Full mark on
the dipstick. See Figure 10.
4.
If low, add oil slowly into the engine oil fill. Do not overfill. After adding oil,
wait one minute and then recheck the oil level.
CAUTION
Do not overfill. Overfilling with oil may cause the engine to not start, hard
starting, or engine smoking. If over the FULL mark on the dipstick, drain oil
to reduce oil level to FULL mark on dipstick.
5.
Replace and tighten dipstick.

Changing Engine Oil
The engine oil should be changed in the first 5 hours and then every 50 hours or
once a season. To change the engine oil, proceed as follows:
1.
With engine OFF but still warm, disconnect spark plug wire and keep it away
from spark plug.
2.
Remove the oil fill cap/dipstick from the oil fill tube. See Figure 10.
3.
Turn the steering wheel all the way to the right to better expose the drain
plug.
4.
Clip the oil drain sleeve (packed with this manual) onto the oil drain port,
see Figure 10. Route the opposite end of the sleeve into an appropriate oil
collection container with a capacity great enough to collect the used oil.
5.
Remove the oil drain plug, The oil will begin to drain out of the engine.
6.
After the oil has finished draining, replace the oil drain plug and tighten. Be
careful not to overtighten.
7.
Remove the oil drain sleeve and store for later use.
8.
Refill the engine with new motor oil until the oil level on the dipstick reads
FULL. Replace the oil fill cap/dipstick.
Used oil is a hazardous waste product. Dispose of used oil properly. Do not
discard with household waste. Check with your local authorities or or contact
1-800-659-5917 for a list of safe disposal/recycling facilities.
Changing the Oil Filter
1.
Drain the oil from the engine as described above.
2.
Remove the oil filter and dispose of properly. See Figure 11.
3.
Before you install the new oil filter, lightly lubricate the oil filter gasket
with fresh, clean oil.
4.
Install the oil filter by hand until the gasket contacts the oil filter adapter,
then tighten the oil filter 1/2 to 3/4 turns.
5.
Add oil as described above.
6.
Start and run the engine. As the engine warms up, check for oil leaks.
7.
Stop the engine and check the oil level. It should be at the FULL mark on the
dipstick.
