Driving on a slope
Determine the slope and side slope ratings for the
machine and determine the slope grade.
Maximum slope rating, stowed position:
GS-3384, GS-3390, 50% 26°
GS-4390
GS-5390 40% 22°
Maximum side slope rating, stowed position:
GS-3384, GS-3390, 50% 26°
GS-4390
GS-5390 40% 22°
Note: Slope rating is subject to ground
conditions and adequate traction.
Operating Instructions
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
vertical 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:
Piece of wood = 144 inches (3.6 m)
Run = 144 inches (3.6 m)
Rise = 12 inches (0.3 m)
12 in ÷ 144 in = 0.083 x 100 = 8.3% grade
0.3 m ÷ 3.6 m = 0.083 x 100 = 8.3% grade
If the slope exceeds the maximum slope or side
slope rating, then the machine must be winched or
transported up or down the slope. See Transport
and Lifting section.
