Before installing a snow plow on the
vehicle, here are some things you
need to know:
Some vehicles are built with a
special snow plow prep package,
called RPO VYU. If the vehicle has
this option, you can add a plow to it,
provided certain weights, such as
the weights on the vehicle's axles
and the Gross Vehicle
Weight (GVW), are not exceeded.
The plow the vehicle can carry
depends on many things, such as:
The options the vehicle came
with, and the weight of those
options.
The weight and number of
passengers intended to be
carried.
The weight of items added to the
vehicle, like a tool box or
truck cap.
The total weight of any
additional cargo intended to be
carried.
Say, for example, you have a 318 kg
(700 lb) snow plow. The total weight
of all occupants and cargo inside
the cab should not exceed
135 kg (300 lb). This means that you
may only be able to carry one
passenger. But, even this may be
too much if there is other equipment
already adding to the weight of the
vehicle.
Here are some guidelines for safely
carrying a snow plow on the vehicle:
Make sure the weight on the
front and rear axles does not
exceed the axle rating for each.
For the front axle, if more cargo
or passengers must be carried,
appropriate counter ballast must
be installed rear of the rear axle.
Counter ballast must be properly
secured so it will not move
during driving.
Follow the snow plow
manufacturer's
recommendations regarding rear
ballast. Rear ballast may be
required to ensure a proper front
and rear weight distribution ratio,
even though the actual weight at
the front axle may be less than
the front axle rating.
