Stop and check surface conditions before entering soft areas.
Select transmission gear range to get power needed in soft area with minimum slipping.
Enter soft area at medium engine rpm.
Keep accelerator pedal steady and keep the M911 Truck Tractor moving until on solid
ground again.
CAUTION
Exercise caution when stuck, or when loss of traction is experienced, to prevent
bouncing. If bouncing is experienced, let up on the throttle and gradually increase
engine rpms to move the vehicle.
If M911 Truck Tractor is stuck, try to pull it out using low range. Place boards, brush,
and similar materials under tires to give extra traction if needed.
If M911 Truck Tractor is stuck and not coupled to semitrailer, use winches to help pull
it out. Attach winch cables to a large tree trunk, another vehicle, or heavy solid object
that will not move under load.
