Determining Vehicle Payload

4.

5

6.

With the occupants in truck for nonnal
hopper spreader operation, weigh vehicle to

obtain gross vehicle weight (GVW).
Subtract the GVW from the GVWR to

detennine the available payload to carry the
material.

Obtain the weight per cubic yard (lb./cu. yd.)
of the desired material from Table 2, page 4.

Use Table 3 to record information.

I. 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
(FGA WR), and Rear Gross Axle Weight
Rating (RGA WR) from the certification label

located inside the driver-side door jam.

Divide the weight into the payload to
detemline the maximum volume of material
that can be carried.

7. Compare the maximum volume to Figures I
or 2 on page 4 to determine the maximum
height of the material in the hopper spreader.

8. Fill hopper with the material to the height
calculated. 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 Table 3 on page 6 for an example and

worksheet.
