Differential Lock; Adjusting The Cutting Height - Husqvarna PT 26D Operator's Manual

Presentation

11. Differential Lock

The differential lock is electro-hydraulic. It is operated
by a pedal controlled switch. The differential lock only
works longitudinally, it ensures operation on at least
one front wheel and one rear wheel. This means that
you can turn the machine with engaged differential
lock without causing any interruptions in the power
transmission or damage to the lawn.
As the differential lock is not mechanical, it can be
engaged or disengaged without limitation, even when the
machine freewheels or in the event of wheel spin. When
the pedal is released, the differential lock disengages
without the driver having to carry out any other
operations. The differential lock only works at low speed
and is active both up and down slopes.

Adjusting the cutting height

.
The cutting height adjustment allows the cutting height
to be adjusted in seven different positions 25.4 mm -
127 mm (1" - 5").
In order to obtain an even cutting height, it is important
that the settings are in the same positions and the air
pressure is the same in the front wheels, 100 kPa /
1.0 bar / 14.5 PSI and in the cutting unit's pivot wheels
150 kPa / 1.5 bar / 21,7 PSI
When the adjustments have been made, the cranks
should be released using the button in the crank and set
to a position that does not catch on any bushes or similar.
