Maintenance
Lubricating the Machine
Regularly lubricate the 5 grease fittings of each cutting
unit (
) with No. 2 lithium grease.
There are 2 lubrication points on the front roller, 2 on
the rear roller, and 1 at the reel-motor spline.
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
(
and
).

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.
