Lubrication
Grease Fittings
The grease fittings on the mower should be greased at
least every 25 hours. Lubricate using a No. 2
multi–purpose lithium base grease. A hand operated
grease gun is recommended for best results.
1. Wipe each grease fitting with a clean rag.
2. Grease components as follows:
• Cutting unit reel bearings, drive shaft bearing, front
roller or support, yoke pivot and pull arm bushings and
rear cutting unit and yoke rollers (Fig. 25).

1. Pipe plug
• To lubricate the rear cutting unit and yoke rollers,
remove pipe plugs at each end, install 1/8-27 NPT
grease fittings, lubricate bearings, remove fittings and
replace pipe plugs (Fig. 25). Apply grease to enclosed
bearing areas only until pressure is felt against the
grease gun.
• Front roller or support, yoke pivot and pull arms; apply
grease to bearings until it begins to show (Fig. 25).
Important Do not apply too much pressure or grease
seals will be permanently damaged.
3. Wipe excess grease away.
Greasing Traction Clutch
1. At the end of each seasons cutting, remove the traction
clutch assembly and clean and re–pack the cam and
roller assembly with No. 5 multi–purpose (wheel)
bearing grease (Fig. 26). Take extreme care to make
sure that grease is kept off the clutch friction discs
(Fig. 26).
