Towing Safety Precautions
Tow Bar to Vehicle Connection (Coupler Only)
1. Check the vehicle hitch ball, and mixer's coupler for signs
of wear or damage. Replace any parts that are worn or
damaged before towing.
To reduce the possibility of an accident while transport-
ing the mixer on public roads, always make sure that the
mixer towing components and the towing vehicle are in
good operating condition and both units are mechani-
cally sound.
CAUTION
If the mixer tow bar is deformed or damaged, replace the
entire tow bar. NEVER tow the mixer with a defective tow
bar. There exists the possibility of the mixer separating
from the towing vehicle.
CAUTION
The following list of suggestions should be used when tow-
ing the mixer:
■
Check with your county or state safety towing regulations
department before towing your mixer.
■ Make sure that the hitch and coupling of the towing vehicle
are rated equal to, or greater than the trailer "gross vehicle
weight rating" (GVWR).
■ ALWAYS inspect the hitch and coupling for wear. NEVER
tow the mixer with defective hitches, couplings, chains
etc.
■ CHECK the tire air pressure on both the towing vehicle
and the trailer. Also check the tire tread wear on both
vehicles.
■ ALWAYS make sure the mixer is equipped with a "Safety
Chain".
■ ALWAYS attach trailer's safety chain to the frame of tow-
ing vehicle.
■ ALWAYS make sure that the towing vehicle's directional,
backup, and brake lights are working properly.
■ Remember in most cases the maximum speed unless
otherwise posted for highway towing is 55 MPH, however
before towing your mixer, check your local state, and
county vehicle towing requirements. Recommended
off-road towing is not to exceed 10 or 15 MPH or less
depending on type of terrain.
■ Place chocked blocks underneath wheels to prevent roll-
ing, while parked, if disconnected from towing vehicle.
■ Inflate tires to correct pressure, inspect tires for cuts, and
excessive wear. See Table 9 (Tire Wear Troubleshooting).
■ When towing of the mixer is required, place the drum in
the up position (mouth facing upwards) and lock the drum
latch.

2. Use only a 2-inch ball diameter (towing vehicle), this will
match the mixer's 2-inch coupler. Use of any other ball
diameter will create an extremely dangerous condition
which can result in separation of the coupler and ball or
ball failure.
3. After tow bar has been connected to mixer (see next
page), attach mixer's coupler to the hitch ball on the
towing vehicle securely and make sure the lock lever
is in the down position (locked).
Mixer Tow Bar Vehicle Connection (Pintle and Loop)
1. Make sure the bumper on the towing vehicle is
equipped to handle either a pentle or loop type tow bar
configuration.
2. After tow bar has been connected to mixer (see next
page), secure either type of tow bar to the towing vehicle,
following state and county towing regulations.
3. As a minimum, use a 1/2-inch bolt and nylock nut grade
5 when securing the tow bar to the towing vehicle and
to the unit being towed.
■ ALWAYS make sure that the fuel valve lever is in the OFF
position (gasoline models only).
■ Check wheel mounting lug nuts with a torque wrench.
Torque wheel lug nuts as described in the maintenance
section of this manual.
■ Check tightness of U-clamp nuts, torque suspension
hardware as referenced in the maintenance section of
this manual.
■ Avoid sudden stops and starts. This can cause skidding,
or jackknifing. Smooth, gradual starts and stops will
improve gas milage.
■ Avoid sharp turns to prevent rolling.
