PRESENTATION Presentation Speed limiter Congratulations on your choice of an excellent quality product that will give you great pleasure for many years. This operator’s manual describes PR 17, PR 17 AWD, PF 21 and PF 21 AWD. The machines are equipped with a four-stroke VTwin engine from Kawasaki. The speed of the machine is steplessly regulated with two pedals. Pedal (1) is used to drive forwards, and pedal (2) to drive backwards.
PRESENTATION Cutting unit Lowering the Unit (Mowing Position) PR 17 and PR 17 AWD can be equipped with three different cutting units. CombiTurf 94, CombiTurf 103 and CombiTurf 112 If the cutting unit is secured in the transport position using the mechanical lifting lever, move the mechanical lifting lever to the cutting position. PF 21 and PF 21 AWD can be equipped with two different cutting units. CombiTurf 112 and CombiTurf 122 Move the hydraulic lifting lever forwards to engage the cutting position.
PRESENTATION Mowing Position If the lock button is pressed in and the lever is moved forwards the unit will be lowered and the blades will automatically start to rotate (mowing position). If this does not happen it is probably because the unit has been lifted with the hydraulic lifting lever. Lower the unit to the mowing position with the lever for the hydraulic lift. The seat springing can be adjusted by moving the rubber stops in their mountings on the underside of the seat.
