The transmission fan and cooling fins should be kept clean 

to ensure proper cooling.
Do not attempt to clean fan or transmission while engine 

is running or while the transmission is hot. To prevent pos-

 si ble damage to seals, do not use high pressure water or 

steam to clean transmission.
• 

Inspect cooling fan to ensure fan blades are intact and 

clean.

•  Inspect cooling fins for dirt, grass clippings and other 

materials. To prevent damage to seals, do not use com-

pressed air or high pressure sprayer to clean cool ing fins.

The transaxle was sealed at the factory and fluid main te-

 nance is not required for the life of the transaxle.  Should 

the transaxle ever leak or require servicing, contact your 

near est au tho rized ser vice center/department.

Only use high quality detergent oil rated with API service 

classification SG-SL.  Select the oil’s SAE viscosity grade 

according to your expected operating temperature.

NOTE:  Although multi-viscosity oils (5W30, 10W30 etc.) 

improve starting in cold weather, they will result in increased 

oil consumption when used above 32°F/0°C.  Check your 

engine oil level more frequently to avoid possible engine 

damage from running low on oil.

Change the oil after every 50 hours of operation or at least 

once a year if the tractor is not used for 50 hours in one year.
Check the crankcase oil level before starting the engine 

and after each eight (8) hours of operation.  Tighten oil fill 

cap/dipstick securely each time you check the oil level.    

Check V-belts for deterioration and wear after 100 hours 

of operation and replace if necessary. The belts are not 

ad just able. Re place belts if they begin to slip from wear. 

Replace the engine oil filter every season or every other 

oil change if the tractor is used more than 100 hours in 

one year.
NOTE: If needed, remove lower dash covers using steps 

from "Lower dash cover removal" section of this manual.

• 

Remove oil fill cap/dipstick.  Be careful not to allow dirt 

to enter the engine when changing oil.

• 

Remove yellow cap from end of drain valve and install 

the drain tube onto the fitting. 

•  Unlock drain valve by pushing inward and turning 

coun ter clock wise. 

•  To open, pull out on the drain valve. 

•  After oil has drained completely, close and lock the 

drain valve by pushing inward and turning clockwise 

until the pin is in the locked position as shown. 

• 

Remove the drain tube and replace the cap onto to the 

bottom fitting of the drain valve. 

•  Refill engine with oil through oil fill dipstick tube.  Pour 

slowly.  Do not overfill.  For approximate capacity see 

“PRODUCT SPECIFICATIONS” section of this man u al.

•  Use gauge on oil fill cap/dipstick for checking level.  

Ensure dipstick cap is tightened securely for accurate 

reading.  Keep oil at “FULL” line on dipstick. Tighten 

cap onto the tube securely when finished.

CAUTION: Remove lower dash cover carefully to ensure 

cover tabs are not broken.
•  Slide lower dash cover up to release cover tabs from 

tapered slots in lower dash and remove.
