The rider is fitted with a Briggs & Stratton four-stroke overhead valve engine. Using the left and right steering controls, the flow is regulated and thereby the direction and speed.

Bypass linkages Blade control lever Motion control levers Fuel tank cap 17 ContRoLs SteeringControlLevers The machine's speed and direction are continuously variable using the two steering controls. The steering controls can be moved forward or backward about a neutral position. Furthermore, there is a neutral position, which is locked if the steering controls are moved outward. When both controls are in the neutral position (N), the machine stands still. By moving both controls an equal amount forward or backward, the machine moves in a straight line forward or backward respectively. In order, for example, to turn right while moving forward, move the right control towards the neutral position. The rotation of the right wheel is reduced and the machine turns to the right. Zero turn can be achieved by moving one control backward (behind the neutral position) and carefully moving the other steering control forward from its neutral position. The rotation direction when zero turning is determined by which steering control is moved backward behind the neutral position. If the left steering control is pulled backward, the machine turns to the left. If the steering controls are in uneven positions when standing still or do not fit in the slots for moving the controls outward, they can be adjusted. 8050-003 Steering controls WARNING!Themachinecanturnveryrapidlyif onesteeringcontrolismovedmuch furtherforwardthantheother. 1.

In order to increase or decrease the engine speed, the control is moved forward or back respectively. Avoid idling the engine for long periods, as there is a risk of fouling the spark plugs. USEFULLTHROTTLEWHENMOWING, for best mower performance and battery charging. 8050-006 Throttle control IgnitionSwitch The ignition switch is placed on the control panel and is used to start and stop the engine.

Lubricate with a grease gun, one zerk for each steering control shaft. Grease from well-known brand names (petrochemical companies, etc. ) usually maintains a good quality.
