Maintenance
Lubricating the Machine
Regularly lubricate the 6 grease fittings of each cutting unit
(
Figure 22 ) with No. 2 lithium grease.
There are 2 lubrication points on the front roller, 2 on the
rear roller, and 2 for the reel bearing.
Note:
Lubricating the cutting units immediately after
washing helps purge water out of the bearings and
increases bearing life.
1. Wipe each grease fitting with a clean rag.
2. Apply grease until clean grease comes out of the roller
seals and the bearing relief valve.
3. Wipe any excess grease away.

Relief-Grinding the Reel
The reel has a land width of 1.3 to 1.5 mm (0.050 to 0.060
inch) and a 30-degree relief grind.
When the land width gets larger than 3 mm (0.120 inch) wide,
do the following:
1. Apply a 30 degree relief grind on all reel blades until
the land width is 1.3 mm (0.050 inch) wide (
Figure 23
and Figure 24 ).
Figure 23
Model 036321
1. 30 degrees 2. 1.3 mm (0.050 inch)
Figure 24
Model 03623
1. 1.3 mm (0.050 inch) 2. 30 degrees
2. Spin grind the reel to achieve <0.025 mm (0.001 inch)
reel run-out.
Note:
This causes the land width to grow slightly.
Note:
To extend the longevity of the sharpness of the edge
of the reel and the bedknife—after grinding the reel and/or
the bedknife—check the reel-to-bedknife contact again after
cutting 2 fairways, as any burrs will be removed, which may
create improper reel-to-bedknife clearance and thus accelerate
wear.
