2-37. OPERATING IN DEEP MUD
a. General.
(1) Use tire chains in deep mud operations.
CAUTION
Tire chains must be used on all matching sets of driving wheels.
Attempting to operate vehicle in deep mud when only one driving
wheel is equipped with tire chain can result in serious damage to
tire and/or power train.
b. Driving Vehicle.
(1) Approach large water-filled chuck-
holes with caution. Chuckhole depth is
difficult to determine, and vehicle may
become mired.
(2) Be alert at all times to engine and
vehicle speed. Be prepared to downshift
transmission gearshift lever (3) and transfer
selector lever (4), if necessary, to prevent
vehicle from bogging down and becoming
mired.
(3) Skidding, loss of steering, and
traction, are operating problems in mud.
When rear end skidding occurs, immediately
turn front wheels in direction of skid. Let up
on accelerator pedal (5) and apply service
brakes (2) gradually. Do not depress clutch
pedal (1).
CAUTION
Use a second vehicle with winch to recover vehicles sunk in deep
mud. Do not spin wheels. Do not attempt to jump vehicle out of
deep mud with quick transmission gear changes.
