Driving the Mower
To drive the mower, firmly grasp the respective drive control levers with your right and left hands. Slowly and evenly move both drive control levers forward. The mower will start to move forward. As the drive control levers are pushed farther forward, the speed of the mower will increase. To slow the mower, move the drive controls levers rearward to attain the desired speed, or move the drive control levers to the neutral position to stop the mower.
Turning the Mower While Driving Forward
To turn, move the drive control levers so that one is rearward of the other. The mower turns in the direction of the rearward lever. The greater the distance between levers, the sharper the turn. For a pivot turn, move one lever to neutral and the other forward.
Driving the Mower In Reverse
Slowly move both drive control levers rearward to move in reverse. Pushing levers further forward increases speed. Move levers forward to slow, or to neutral to stop.
Turning While Driving Rearward
Move levers so one is forward of the other to turn. Mower turns in direction of forward lever. To pivot turn, move the turn-side lever to neutral and the other rearward.
