Running

Depress one operator presence lever and move the speed control to the desired speed. Pull the blade engagement control upwards. Set the desired rpm with the throttle. The best cutting and bagging is obtained with engine at top rpm.

While on level terrain, squeeze both drive levers slightly. Using thumbs, slide each neutral lock out the locked position. Slowly release both drive levers at the same time to begin forward motion.

The steering system of this mower uses individual right and left drive levers on the handle bars. Squeezing either lever will reduce the speed to that wheel. With the opposite wheel still under power, a turn is accomplished.

If the drive lever is squeezed even tighter the wheel will go into reverse and a tighter more abrupt turn is accomplished. Turn left by squeezing the left hand lever or turn right by squeezing the right hand lever.

Reverse

The mower moves to the reverse gear when both drive levers are pulled fully upward to the handles.

Tracking

If the mower is not tracking straight, check the air pressure in both rear tires. Recommended air pressure is 15 psi (1 bar). Tracking should be checked on a flat, level surface.

See Tracking Adjustment in the Controls section.
