LOADING
DETERMINING VEHICLE PAYLOAD
1. Install the hopper spreader and optional
equipment according to the instructions.
2. Install or attach any other equipment that will be
on the vehicle while the hopper spreader will be in
use (step bumper, trailer hitch, snowplows, etc.).
Fill gas tanks.
3. Obtain the Gross Vehicle Weight Rating (GVWR),
Front Gross Axle Weight Rating (FGAWR) and
Rear Gross Axle Weight Rating (RGAWR) from
the certification label located inside the driver-side
door jamb or door.
4. With the occupants in the truck for normal hopper
spreader operation, weigh the vehicle to obtain
gross vehicle weight (GVW).
5. Subtract the GVW from the GVWR to determine
the available material payload.
6. Obtain the weight per cubic yard (lb/cu yd) of
the desired material. Divide the weight into the
payload to determine the maximum volume of
material that can be carried.
7.
Compare the maximum volume to determine the
maximum height of the material in the hopper
spreader.
8.
Fill the hopper with the material to the calculated
height. Reweigh the vehicle with occupants
and verify the GVW, Front Gross Axle Weight
and Rear Gross Axle Weight are less than the
vehicle's ratings.
9. Repeat Steps 6–8 for each type of material.
This Owner's Manual covers vehicles that have been
recommended for carrying the hopper spreader. Please
see your local dealer for proper vehicle applications.

Material densities are approximate and are based on dry,
loose material. It is the responsibility of the operator to
know the weight of the material to be spread and the vehicle
carrying capacity.
WARNING
Overloading could result in an accident or
damage. Do not exceed GVWR or GAWR as
found on the driver‑side cornerpost of vehicle.
WARNING
New untitled vehicle installation of a spreader
requires National Highway Traffic Safety
Administration altered vehicle certification
labeling. Installer to verify that struck load of
snow or ice control material does not exceed
GVWR or GAWR rating label and complies
with FMVSS.
CAUTION
Read and adhere to manufacturer's
ice‑control material package
labeling, including Material Safety
Data Sheet requirements.
