The cutting unit must be lubricated regularly. If machine is
operated under normal conditions, lubricate castor bearings
and bushings with No. 2 general purpose lithium base
grease or molybdenum base grease, after every 8 hours of
operation or daily, whichever comes first.
1. The cutting unit has bearings and bushings that must be
lubricated, and these lubrication points are: front castor
spindle bushings (2) (Fig. 26); front castor wheel
bearings (4) (Fig. 26); rear castor wheel bearings (2)
(Fig. 28); blade spindle bearings (3) (Fig. 28); right and
left push arm ball joints (Fig. 28); drive shaft (3)
(Fig. 28) idler arm pivots (3) (Fig. 29); and deck pivot
pins (4) (Fig. 30)
