Operating the Three Wheel Rider
THREE WHEEL RIDER DRIVING PRACTICE
The speed and steering controls of the Three Wheel rider are
responsive
, and learning to gain a
smooth
and
effi-
cient
control of the riders forward, reverse, and turning movements will take some practice.
Spending some time becoming familiar with how the unit accelerates, travels, and steers before you begin mow-
ing is absolutely essential to getting the most out of the three wheel rider.
Locate a smooth, flat area of your lawn — one with plenty of room to maneuver. (Clear the area of objects,
people and animals before you begin.) Operate the unit at mid-throttle during this practice session (ALWAYS operate
at full throttle when mowing), and turn slowly to prevent tire slippage and damage to your lawn.
We suggest you begin practicing straight travel in both the forward and reverse directions. Next practice turning in
both the forward and reverse directions to understand how the tractor reacts. Practice in an area large enough to
make a turn safely.
You must release the parking brake prior to moving the transmission foot control pedal.
Driving the Mower
1. Sit on the seat and adjust the seat so that you can
comfortably reach all the controls and see the dash
panel.
2. Review speed & direction decal (Figure 4.)
3. Make sure the parking brake is engaged.
4. Make sure the PTO switch is disengaged.
5. Start the engine (see STARTING THE ENGINE).
6. Disengage the parking brake.
7. Depress the front of the foot control pedal to travel
forward. Release the pedal to stop. Note that the
further down the pedal is depressed the faster the
mower will travel.
8. Stop the tractor by releasing the foot control pedal,
setting the parking brake, and stopping the engine
(see STOPPING THE ENGINE & MOWER).
9. The braking action of the tractor increases as the
service brake pedal is gradually depressed. Under
normal conditions use of the service brake pedal will
not be required, however if the mower continues to
roll when the transmission foot control pedal is
returned to neutral, the service brake pedal can be
used to stop rotation of the drive wheels.
