    This operator’s manual describes the Rider ProFlex 21 II. The Rider ProFlex 21 II is fitted with a Kawasaki four-stroke V-Twin engine developing 21 horse power. Power transmission from the engine is via a hydrostatic gearbox that allows variable speed controlled by the foot pedals.

  • Page 16: Throttle Control

    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.

  • Page 17: Cutting Unit

    Cutting Unit As standard, the Rider ProFlex 21 II is fitted with a Combi 122 cutting unit with a cutting width of 122 cm. The Combi unit functions as a BioClip unit when a BioClip plug is fitted, but can be set to rear ejection by removing the BioClip plug.
