LUBRICATION

Mower Deck Gearbox Lubrication

On gear driven decks, the mower deck gearboxes (tee gearbox and blade drive gearboxes) are connected as a unitized assembly,­ and oil flows freely between them. The gear­boxes are permanently lubricated (oil filled) and sealed requiring no scheduled lubrication. However,­ the gearbox oil seals should be checked every 25 hours for indication of an oil leak; particularly the lower seals on the blade drive gearboxes should be inspected, since they operate in a dirty en­vironment. If an oil leak is noted, replace the oil seal and relubricate the gearbox assembly as follows:

1.Remove gearbox cover (footrest). Deck orien­ tation should be the normal operating position.

2.Clean the area around the individual gearbox cover plates to prevent contaminants from en­ tering the gearcase.

3.Remove the screws securing the cover plates on the blade drive gearboxes.

4.Check the level of lubricant in the gearboxes. If the lubricant is low, add SAE E.P. (Extreme Pressure) 80W-90 (API GL-5) gear lube until the oil level is up to (submerges) the horizontal shaft in the gearbox (shaft parallel to cover plate).

NOTE: In case the gearboxes are completely drained of oil, approximately 5 fl. oz. (15 cl) of oil per gearbox is required to refill the gear drive assembly.

NOTE: Since the gearboxes are connected as a unit by connector tubes, it is necessary to add oil slowly. Allow a few minutes after adding oil for the oil to flow throughout the assembly and the oil level to stabilize before reassembly.

IMPORTANT: DO NOT overfill the deck gear­ boxes. The gearbox assembly is not vented, and overfilling with oil will cause excessive pres­ sure and result in oil leaks.

5.Check condition of the cover gasket and replace if worn or damaged. Reinstall gearbox cover plates; torque screws to 24 lb·in (3 N·m).

Mower Deck Spindle Lubrication

For the DS42 Belt Drive mower deck, lubricate each deck spindle grease fitting every 25 hours. Use SAE general purpose lithium or molybdenum base grease for grease fittings.

Transaxle Lubrication

•The transaxle oil lubrication is SAE 20W-50 (API Service Class SL or higher) engine oil.

•Inspect both transaxle cases and hoses after ev- ery 100 hours of operation for visible leaks.

•The fluid level of each transaxle can be checked visually by looking at the fluid level in the expansion reservoir. When the transaxles are cold, the fluid level in the expansion reservoir should be between 1/4 in. and 1/2 in. (0.64 cm and 1.27 cm).
