side to side and front to rear movement. The pull-type
unit will be anchored front to rear.
For the mounted unit, tighten tractor lower 3-point arm
anti-sway mechanisms to prevent side to side move-
ment.
For the pull-type unit, raise cutter with the standard
height adjustment crank or the optional hydraulic cylin-
der. The crank must always be rotated clockwise until
the crank begins to raise the cutter. With either the
height adjustment crank or the optional hydraulic cylin-
der, lower cutter to transfer its weight to the jack
stands, but do not raise the rear wheels off of the
ground. If the optional hydraulic cylinder is installed,
the crank arm must be turned clockwise until weight
transfer starts to occur. This allows the mechanical
height adjustment to keep the cutter in a raised position
in the event of a hydraulic failure.
When blocking, you must consider overall stability of
the unit. Just placing jack stands under the unit will not
ensure your safety. The working surface must be level
and solid to support the weight on the jack stands.
Ensure jack stands are stable both top and bottom, and
mower is approximately level. With full mower weight
lowered on jack stands, test blocking stability before
working underneath cutter.
LUBRICATION
Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
The accompanying illustration shows the lubrication
points. The chart gives the frequency of lubrication in
operating hours, based on normal conditions. Severe
or unusual conditions may require more frequent lubri-
cation.
Use a lithium base grease with a No. 2 NGLI consis-
tency for all locations. Be sure to clean fittings thor-
oughly before attaching grease gun.
One good pump of most guns is sufficient.
Use a high quality lubricant with a viscosity index of
80W or 90W and an API service rating of GL-4 or 5 in
gearbox(es).
Use NeverSeez® or equivalent to lubricate torsion
bars.
Raise or lower cutter and expose lube slot in rear half
of PTO shielding.
Insert grease gun through slot and apply grease to all
sides of shaft where it enters tube. Remove safety
blocks and operate 3-point lift to distribute grease over
working area of shaft.
It may be necessary to disconnect PTO shaft from trac-
tor to expose slot.
To prevent torsion bars from seizing and/or binding and
causing excessive loads on gearbox bearings, lubri-
cate as detailed.
Remove shielding. Remove nuts and bolts from torsion
bars and slide out of center gearbox. Coat all four sides
approximately four inches from each end with Never
Seez® or equivalent. Install torsion bars. Refer to
Maintenance section for torsion bar installation.
Lubricate before storage to prevent rust, and at the
beginning of each season.
