4.5 GROUND TRAVEL AND STEERING

- IMPORTANT -

If you are not familiar with the operation of a walk behind mower with a hydrostatic transmission, the steering and ground speed operations should be learned and practiced in an open area, away from buildings, fences, or obstructions.

Learn the operation on flat ground before operating on slopes.

Start practicing with a slow engine speed and slow forward travel.

Learn to feather the steering controls to obtain a smooth operating action.

Practice operating the mower until you are comfortable with the controls before proceeding to mow.
