2. With the blades disengaged, and the drive levers locked securely in the thumb latches, start the
engine.
3. Move the ground speed lever to the fast position.
4. Using two 9/16” wrenches, loosen the jam nut on the bottom side of the turnbuckle on the
motion control linkages.

6. Holding down either or both O.P. levers, unlock the thumb latches and release the drive levers.
The tires should be rotating full speed forward.
