Differential Lock, Pf 21; Stopping The Engine, Pf 21 - Husqvarna Rider ProFlex 21 Operator's Manual

5. If the cutting unit does not lower completely, or if
the blades do not rotate, lower the cutting unit
completely using the hydraulic lifting lever.
In order to ensure that the hydraulic cylinder is in
the outer position, hold the lever in the forward
position for a half to one second.

Differential lock, PF 21

The differential lock can be used during operation
via the pedal on the left side.
In order not to get stuck, one can engage it shortly
before the obstacle.
1. Engage the differential lock when necessary by
pressing the pedal. If a wheel spins, let the drive
pedal up a little.
2. Ensure that the differential lock is disengaged
when the pedal is released. Use small steering
movements or reverse a little until the pedal
returns to its normal position.

Stopping the engine, PF 21

If the engine has been worked hard, it is preferable to
let the engine idle for a minute so it runs at its normal
working temperature when stopped. Avoid idling the
engine for long periods, as there is a risk of carbon
build-up on the spark plugs.
1. Lift the cutting unit with the hydraulic lifting lever.
The unit can then be secured in the raised position
if necessary by moving the mechanical lifting lever
backwards to the lock position.
If the cutting unit is left in the lower position,
the start lock circuit will prevent you starting
the engine.
