Zero-Turn Riding Mower Driving Practice

Before attempting to drive the zero-turn riding mower make
sure you have read the FEATURES AND CONTROLS
section and understand the location and function of all the
unit's controls.
The ground speed control levers of the zero-turn riding mower
are responsive and learning to gain a smooth and efficient
control of the unit's forward, reverse, and turning movements
will take some practice.
Before you begin mowing, spend some time going through
the maneuvers shown in this manual and become familiar
with how the unit accelerates, travels, and steers.
Locate a smooth, flat area of your lawn 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 with the Smooth Travel procedure,
and then advance through the forward, reverse, and turning
maneuvers.
