6.1
Mower Preparation
Units of up to 36” long can be ground
in frame, this includes most machines
including Greens mowers and Fairway
units. In order to spin / drive the reel,
one end of the reel shaft drive must be
exposed. This will require the removal
of the hydraulic motor, the chain / belt
or cover depending on which type
of unit is being ground. This should
be done before the mower is on the
grinder (see example Fig. 6.1).
Ensure that the mower is clean and
that both reel and roller bearings are
in good condition. Also ensure that
the bedknife has been sharpened, if
necessary, and replaced with a small
amount of clearance between it and the reel.
6.1.1 Unscrew the traverse engagement screw until it is released from the traverse chain so that
fork/grindstone can be traversed manually along the mainshaft.
6.2.
Mounting Mower
The mainshaft / Grinding stone should be wound down to its lowest position and the unit
placed on the table. The unit should then be carefully moved towards the multifix brackets
or front roller brackets, which can be adjusted in any direction to allow the unit to be fixed
in such a position that the grinding wheel can be raised towards the reel without coming
into contact with either the bedknife or the front roller/groomer.
6.3.
Clamping
With the mower correctly positioned
the radiused pressure bar) is moved
forward to rest on the rear of the mower
and locked in position by operating the
toggle switch on the operator control
panel downwards. The operator
should release the toggle switch as
the pressure bar engages the cutting unit
thus retaining pressure on the mower until the
grinding operation is completed. A backing up plate
is supplied to protect the rear of the units and to evenly
disperse the force of the pressure bar across the width of
the mower (see Fig. 6.3).
