Adjusting the Center Cutting Unit
Height-of-Cut Correction
With all cutting units set at the same HOC as shown
by the indicator rings, you may notice that the center
cutting unit produces a higher cut finish compared to
that of the left and right cutting units. The machine
pulls the center cutting unit whereas the left and right
cutting units are pushed; this affects the cutting unit
angle relative to the ground. The amount of HOC
variation that results from this effect is also influenced
by the terrain, but you can achieve satisfactory results
by setting the center cutting unit HOC indicator ring
lower than the left and right cutting unit settings.
Controlling the Position of
the Individual Cutting Units
Use the 3 lift-control switches to raise or lower the
cutting units independently.
Lowering the Cutting Unit
1.
Press the cutting-unit-drive switch to the
F
ORWARD
R
OTATION
position.
2.
Press the lift-control switch forward and release.
Note:
The cutting unit engages when it is
approximately 150 mm (6 inches) above ground
level. The cutting unit is in ‘float’ mode, and
follows the ground contours.
Note:
The lift-control switch automatically
returns to the (N
EUTRAL
) position when you
release it.

Raising the Cutting Unit
1.
Pull and hold the lift-control switch.
2.
Release the lift-control switches when the cutting
units are at the needed height.
Note:
The lift-control switches automatically return to
the (N
EUTRAL
) position when you release it and the
cutting unit arms hydraulically lock into position.
Cutting Unit Limited-Lift Position
Limiting Cutting Unit Lift When Driving
Forward
Note:
The limited lift function for driving forward is
enabled by default.
•
While driving forward, momentarily pull the
lift-control switch(s).
Note:
The cutting unit(s) shuts off and it raises
approximately 150 mm (6 inches) above ground
level.
•
The limited lift function shuts off when the cutting
unit is lowered and running.
Limiting Cutting Unit Lift When Driving
Backward
Note:
You must enable the limited-lift function in the
InfoCenter to automatically lift the cutting units when
driving backward.
•
When the limited-lift function is enabled, driving
the machine backward causes all cutting units
raise to the limited-lift position.
Note:
The cutting unit(s) raises approximately
150 mm (6 inches) above ground level.
Important:
The cutting units continue to run
while using limited lift and driving the machine
backward.
•
Driving the machine forward again causes the
cutting unit lower to the float position.
Using the Cutting-Unit Turnaround
Feature
Note:
You must enable the turnaround feature for
the center lift-control switch in the settings menu of
the InfoCenter.
•
Momentarily pull the lift-control switch for the
center cutting unit to raise all cutting units to the
limited lift position.
•
Momentarily push down the lift-control switch for
the center cutting unit to lower all cutting units to
the float position.
