INTRODUCTION - Continued
NOTE
•
When possible, front towing is preferred for larger vehicles, because
braking can be controlled to the rear of most vehicles with the towing
air lines.
•
The disabled vehicle's operator manual must be checked for towing
preparation before the vehicle is towed.
•
For detailed instructions on towing procedures refer to FM 4-30.31.
•
Because of M984A wrecker rigid retrieval system, ALL OFF-ROAD
TOWING must be performed with towed vehicle's front or rear tires
lifted off ground.
The M984A wrecker is capable of towing a wide range of vehicles. The towing cylinders
and crosstube attach to the disabled vehicle by means of adapters that mount on the
crosstube. The lift and tow cylinders are used to position the adapters, raise/lower and tow
the disabled vehicle. Chains are attached between the wrecker and disabled vehicle for
safety purposes.

The M984A wrecker will perform two types of towing.
a.
Lift and Tow (OFF ROAD) - With the retrieval system attached to one end (front
or rear) of the disabled vehicle, it is raised as high as possible, but (lifted tires)
not more than 1 ft. (30 cm) above the ground.
b.
Tow (HIGHWAY) - With the retrieval system attached (same as lift and tow) to
the front of the disabled vehicle, it is towed with all tires on the ground. If required,
front or rear of disabled vehicle may be lifted (lifted tires) not more than 1 ft. (30
cm) above the ground. Refer to FM 4-30.31 (Volume 2, WP 0200) for more
