Using the Kickstand When
Tipping the Cutting Unit
Whenever the cutting unit has to be tipped to expose
the bedknife/reel, prop up the rear of the cutting unit
with the kickstand (supplied with the traction unit) to
make sure that the nuts on the back end of the bedbar
adjusting screws are not resting on the work surface
(Figure
24).

Each cutting unit has 5 grease fittings
must be lubricated regularly with No. 2 lithium grease.
The lubrication points are the front roller (2), the rear
roller (2), and at the reel motor spline (1).
Note:
after washing helps purge water out of the
bearings and increases bearing life.

Relief-Grinding the Reel
The new 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:

contact again after cutting 2 fairways, as any burrs
will be removed, which may create improper reel to

Lubricating the cutting units immediately
Wipe each grease fitting with a clean rag.
Apply grease until clean grease comes out of
the roller seals and the bearing relief valve.
Wipe any excess grease away.
Apply a 30 degree relief grind on all reel blades
until the land width is 1.3 mm (0.050 inch) wide
(Figure
