PRESENTATION Throttle Control The throttle is used to control the speed of the engine and thereby also the rotation speed of the blades. In order to increase or decrease the engine speed, the control is moved forwards or backwards respectively. Avoid idling the engine for long periods, as there is a risk of carbon build-up on the spark plugs.
PRESENTATION Cutting Unit Rider ProFlex 21 AWD can be equipped with cutting units of the types Combi 112 with a 112 cm cutting width and Combi 122 with a 122 cm cutting width. The Combi unit functions as a BioClip unit when a BioClip plug is fitted, but can be set to rear ejection by...
PRESENTATION Cutting Height Adjustment Lever Using the cutting height lever, the cutting height can be adjusted between seven different positions. It is important that the air pressure in both front wheels is equal, 60 kPa / 0.6 bar / 9 PSI, to produce an even cutting height.
PRESENTATION Mechanical Lifting Lever for Cutting Unit The lever is used as a backup lever to put the cutting unit in either the transport or mowing position when hydraulic pressure is unavailable. It can also be used to mechanically secure the cutting unit in the transport position.
PRESENTATION Parking Brake The parking brake is activated as follows: Press down the parking brake pedal. Completely depress the lock button on the steering servo housing. Release the parking brake pedal while keeping the button pressed in. The parking brake lock is automatically disengaged when the brake pedal is pressed down.
PRESENTATION Clutch Control AWD models have separate clutch controls for forward and rear axles. The clutch controls are used to move the Rider when the engine is not running. Pull the controls to the end positions, do not use an intermediate position.
DRIVING Mowing Tips WARNING! Clear the lawn of stones and other objects that can be thrown out by the blades. • Localise and mark rocks and other fixed objects in order to avoid collisions. 6007-212 Mowing Patterns • Begin with a high cutting height and reduce it until the desired mowing result is attained.
DRIVING Clutch Control The clutch controls must be pulled out in order for the Rider to be moved when the engine is shutoff. Should you attempt to drive the machine with the clutch controls pulled out it will not move. The drive on the axle is disengaged when one of the controls is pulled out.
DRIVING Running IMPORTANT INFORMATION The air intake grille in the engine cover behind the driver's seat must not be blocked by, for example, clothing, leaves, grass or dirt. Impaired cooling of the engine. Risk of major engine damage. Before Starting 8009-489 •...
