LUBRICATION

Mower Deck Gearbox Lubrication

NOTE: These instructions apply to all mower decks with gear-driven blades. Refer to DSD52 or DSD62 Mower Deck Lubrication in this section for the DSD52 or DSD62 deck with belt-driven blades.

The mower deck gearboxes (tee gearbox and blade drive gearboxes) are connected as a unitized assem- bly, and oil flows freely between them. The gearbox- es 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 in- spected, since they operate in a dirty environment. If an oil leak is noted, replace the oil seal and relubri- cate 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) 90W oil until the oil level is up to (sub- merges) 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 in-lb (2.7 N⋅m).

DSD52 or DSD62 Mower Deck Lubrication

There are several special lubrication requirements for the DSD52 or DSD62 mower deck in addition to the requirements detailed in the Chassis and Deck Lubrication illustration. Lubricate the locations shown in the Blade Spindle Lubrication and Gear- box, Dolly Wheel, and U-Joint Lubrication photos and check and maintain oil in the belt drive gearbox.

1.Lubricate the blade spindles every 25 hours with two (2) shots of SAE general purpose lithi- um or molybdenum base grease.
