TOWING GUIDELINES
TOWING SAFETY PRECAUTIONS
The following list of suggestions should be used when towing
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
towing 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
rolling,
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.
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.
Tow bar to vehichle 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.
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 (Pentle and Loop)
1. Make sure the bumper on the towing vehicle is equipped
to handle either a pintle 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.
CAUTION — Replacing Towing Components
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 — Inspect Towing Components
To reduce the possibility of an accident while transporting
the machine on public roads, always make sure that the
equipment’s towing components and the towing vehicle
are in good operating condition and both units are
mechanically sound. Remember before towing,
check with
local and state laws for proper compliance.
