UNIT COUNTERBALANCE CONTROL

The driver can change the ground pressure of the cutting
units within preset limits.
To decrease the ground pressure, the handwheel (A) on
the right of the operator's seat is turned clockwise. The
decreased ground pressure of the cutting unit improves
the ability of the vehicle to drive on a slope.
To increase the ground pressure, the handwheel on the
right of the operator's seat is turned anticlockwise. The
increased ground pressure improves the movement of
the cutting unit over ground that is not level. When you
cut on level ground, the normal setting is in the center
between the maximum and minimum positions.

VARIABLE CYLINDER SPEED________________________________________

To adjust the speed of rotation of the cutting cylinders,
the handwheel (A) on the left of the operator is used. In
normal grass conditions, the cylinder speed must be set
to the maximum level. To cut a surface that has very long
grass, the cylinder speed must be decreased below the
maximum level to get good results.
To cut a surface that has short, dry grass, the cylinder
speed must be decreased to prevent damage to the
cylinder and bottom blade. Rotate the hand wheel
clockwise to increase the cylinder speed. Rotate the
hand wheel anticlockwise to decrease the cylinder
speed.

BACKLAPPING LEVER _____________________________________________

The direction of the cutting reel rotation is adjustable and
can operate in three positions:
To cut the grass, move the reel lever forward (A).
To sharpen the blade on the reels, move the lever in a
reverse direction (B).
To keep the reel in a Neutral position, move the lever to
the centre position (C).
See the separate cutting unit Operator's Manual for an
description of the procedure to sharpen the blade on the
reels.
