LOADING
Determining Vehicle Payload
1. Install 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 certi
fi cation label located inside the driver-side
door jam.
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 hopper with the material to the calculated
height. Re-weigh 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 7 and 8 for each type of material.
Refer to "Determining Vehicle Payload" worksheet for
an example and worksheet.
WARNING
Overloading could result in an accident or
damage. Do not exceed GVWR or GAWR ratings
as found on the driver-side door cornerpost of
the vehicle. See Loading Section to determine
maximum volumes of spreading material.
