UNIT COUNTERBALANCE CONTROL
Cutting unit ground pressure can be varied within
preset limits and is controlled by the handwheel (A)
on the right hand side of the operator's seat located
next to the lift/lower lever. The handwheel is turned
clockwise to reduce the groundweight of the cutting
unit, improving slope climbing ability.
The handwheel is turned anti clockwise to increase
the ground weight of the unit. Increased down
pressure will reduce the likelyhood of cutting unit
bounce when cutting undulating ground. When
cutting level ground the normal setting is midway
way between the maximum and minimum positions.
6.10 VARIABLE CYLINDER SPEED
The speed of rotation of the cutting cylinders is adjustable
by means of the handwheel (A) situated on the left hand
side of the operator. Cylinder speed should be set to
maximum in normal cutting conditions. In very long
growth conditions, cylinder speed should be reduced to
obtain best finish,cylinder speed should also be reduced
when cutting very short, dry grass to prevent excesive
cylinder and bottom blade wear. Rotate the hand wheel
clockwise to increase cylinder speed, anticlockwise to
decrease cylinder speed.
6.11 BACKLAPPING LEVER
Sets reel rotational direction with three positions:
(a) forward for mowing, (b) reverse for backlapping
and (c) neutral. See the separate cutting unit
operator's manual for an explanation of the
backlapping procedure.
