SERVICE
MAINTENANCE
Daily maintenance:
Visual inspection for loose parts and accumulation of grass and dirt.
Clean accumulation of grass clippings from beneath deck daily for better mowing performance.
Keep blades sharp. Check the tips of the blades for wear.
25 hour maintenance:
In addition to daily maintenance, grease roller and all bearings.
Spindle housings must be kept full of grease. Grease spindles until grease “shows” at the relief
hole under the spindle drive pulley.
NOTE: The relief hole is under the spindle hub and is not visible. As grease enters the spindle
housing you can hear the sound of escaping air at the relief hole. Stop greasing when the sound of
escaping air ceases.
Check drive belt tension. See Drive Belt Installation on Page 16.
Check 1/4" cap screws on pulley bushings. Torque should be 95 inch pounds. Tighten these cap
screws in alternating sequence 10-12 times to assure equal torque on all cap screws.
Check blade bolts. Torque should be 75-85 ft. lbs.
Annual Maintenance:
In addition to daily and 25 hour maintenance, remove the drive belt and check for cracks or wear.
Rotate each spindle to check for roughness which would indicate bearing wear. Remove and
sharpen blades, clean and wash deck prior to storage. The acid in grass clippings causes
premature corrosion and rusting of mower parts.
Grease all bearings after washing.
