To Reduce Drive Speed
The drive controls can operate in two different drive
speed modes. When the drive speed button light is
on, slow drive speed mode is active. When the
button light is off, fast drive speed mode is active.
Press the drive speed button to select
the desired drive speed.
Driving on a slope
Determine the slope and side slope ratings for the
machine and determine the slope grade.
Maximum slope rating, stowed
position: 30% (17°)
Maximum side slope rating,
stowed position: 30% (17°)
Note: Slope rating is subject to ground conditions
and adequate traction.
Press the drive speed button to the fast drive
speed mode.
Part No. 97773
To determine the slope grade:
Measure the slope with a digital inclinometer OR
use the following procedure.
You will need:
carpenter's level
straight piece of wood, at least 3 feet / 1 m long
tape measure
Lay the piece of wood on the slope.
At the downhill end, lay the level on the top edge of
the piece of wood and lift the end until the piece of
wood is level.
While holding the piece of wood level, measure the
distance from the bottom of the piece of wood to
the ground.
Divide the tape measure distance (rise) by the
length of the piece of wood (run) and multiply by
100.
Example:
rise
Run = 12 ft (144 in) / 3.6 m
Rise = 12 in/ 0.3 m
12 in ÷ 144 in = 0.083 x 100 = 8.3%
0.3 m ÷ 3.6 m = 0.083 x 100 = 8.3%
If the slope exceeds the maximum slope or side
slope rating, the machine must be winched or
transported up or down the slope. See Transport
and Lifting section.
