B. A tractor or skidder equipped with a winch can be used
to pull another vehicle from mud or other areas where it
cannot move using only the drive wheels or tracks. See
Figure 19. Use the following procedure:
WARNING
Use extra care if the traction conditions are
bad or if the vehicles are on a slope. Bad
traction conditions can cause the disabled
vehicle or the tractor to slide. A slope can
require additional distance to stop the
vehicles.
Make sure the wire rope and tow chain have
the capacity to do the job. If the disabled
vehicle does not have a tow pin or other
equipment for towing, carefully fasten the
tow chain around the axle of the disabled
vehicle. Make sure the tow chain is fastened
so that the chain will not cause injury to
people or damage to the vehicle.
An operator must be on the disabled vehicle to operate
the steering and brakes when it is towed.
Operating Techniques
1. Fasten the winch wire rope to the tow bar of the other
vehicle. The wire rope must be in a direction that is
approximately parallel to the direction of travel of the
vehicle. Apply the brakes on the tractor or skidder.
Use the throttle to set the engine speed at a power
level to operate the winch. (Operator experience is
required, because the winch can use most of the
engine power in some vehicles.)
2. Put the control lever in LINE-IN to tighten the winch
wire rope. When the winch wire rope is tight, use the
power from the engine to the winch to pull the vehicle
from the bad area. If the disabled vehicle moves
under its own power, keep the towing wire rope tight
so that the wire rope does not pass under the drive
wheels or tracks of the vehicle being towed.
