VEHICLE APPLICATION INFORMATION
VEHICLE APPLICATION REQUIREMENTS
BALLAST REQUIREMENTS
Ballast (additional weight) is an important part of
qualifying vehicles for snowplow eligibility. Rear ballast
must be used when required to remain in compliance
with axle ratings and ratios as specified by the vehicle
manufacturer.
CAUTION
See your WESTERN® outlet for application
recommendations.
Vehicle application recommendations are based on the
following:
If ballast is required, it is important that it be secured
properly behind the rear axle. A ballast retainer kit is
available from your WESTERN® outlet, P.N. 62849.
• The vehicle with the snowplow installed must
comply with applicable Federal Motor Vehicle
Safety Standards (FMVSS).
NOTE: The ballast retainer kit is for snowplow
vehicles requiring ballast. See your WESTERN®
outlet for the correct amount of ballast required.
Include the weight of the retainer as part of the
ballast requirement. Sand bags are
recommended for use as ballast.
• The vehicle with the snowplow installed must
comply with the vehicle manufacturer’s stated
gross vehicle and axle weight ratings (found on
the driver side door cornerpost of the vehicle)
and front and rear weight distribution ratio. In
some cases, rear ballast may be required to
comply with these requirements. See Ballast
Requirements section.
• WESTERN® Selection List is based on available
vehicle capacity for the snowplow equipment on
a representative vehicle equipped with options
commonly used for snowplowing and with 300 lb.
of front seat occupant weight.
Ballast
Retainer
• Weight of front seat occupants can be adjusted
above or below 300 lb. but vehicle with snowplow
must not exceed vehicle GVWR or GAWR.
• In some cases there may be additional
limitations and requirements.
• Installation, modification, and addition of
accessories must comply with published
WESTERN® recommendations and instructions.
Available capacity decreases as the vehicle is
loaded with cargo or other truck equipment or
snowplow accessories are installed.
• If there is uncertainty as to whether available
capacity exists, the actual vehicle as configured
must be weighed.

GETTING TO KNOW YOUR SNOWPLOW
MVP® SNOWPLOW
The MVP® snowplow consists of all the components
that are readily removable from the vehicle as a unit.
This includes the blade wings, lift frame, T-frame,
hydraulic unit, and the snowplow headlamps. The
snowplow is ready and easy to mount when you need
to plow snow. When plowing is completed, remove the
snowplow.
scratching, and rust. It can be touched up when
necessary.
Blade guides with replaceable flags are included with
your complete snowplow. These help the operator to
visualize the edges of the blade and aid in blade
positioning.
The snowplow shall be installed according to
instructions supplied. WESTERN® outlets are trained to
provide this service and other services for this plow.
T-FRAME AND LIFT FRAME
The wings are attached to the T-frame with a hinge pin,
which allows the wings to extend and retract.
There is no need to unhook the chains or the hydraulic
hoses. When the lift frame is pinned to the stands and
locked in place (see blade label or snowplow removal
section of this manual), the complete UltraMount®
snowplow can easily be moved around on most hard
surfaces.
The hydraulic unit is mounted on the front of the lift
frame. The hoses remain connected to the hydraulic
unit and the rams. The snowplow headlamps are also
attached to the lift frame.
STEEL BLADE WINGS
SNOWPLOW HEADLAMPS
The blade wings on your new snowplow are
constructed of heavy gauge steel. To increase rigidity
and strength, the blade wings are reinforced with
several vertical ribs. The top edges are formed for
added strength and improved appearance.
WARNING
Your vehicle must be equipped with snowplow
headlamps and directional lamps.
The blade comes equipped with a reinforced rubber
snow deflector. This helps keep snow off the
windshield and away from the radiator.
The snowplow headlamps include a set of rectangular,
dual-beam, halogen headlamps plus combination park
and turn signals. A pre-wired harness with a plug-in
module requires no headlamp wire splicing. The
headlamps conform to Federal Motor Vehicle Safety
Standards (FMVSS).
Each of the blade wings has a trip edge. Heavy-duty
compression springs hold each trip edge in the plowing
position (2 springs per blade wing for 8-1/2', 3 for 9-1/2').
The springs are a safety device which allow the trip
edge to rotate back and ride over obstacles such as low
curbs, manhole covers, etc. without damaging the
snowplow, vehicle, or injuring the driver. The trip springs
need no adjustment and offer protection in all blade wing
positions.
When the electrical plugs are connected, the vehicle
headlamps will automatically switch to the snowplow
headlamps when they are turned on.
When the electrical plugs are disconnected, the
headlamps will automatically switch to vehicle
headlamps when they are turned on.
Each wing has a replaceable high carbon steel cutting
edge bolted to the trip angle. These cutting edges
should be replaced when they are worn within 1" of the
carriage bolts.
Replacement 2E1 Seal Beam headlamps are available
through your local WESTERN® outlet.
The blade also features large, adjustable disc-type skid
shoes. These rotate 360° for longer wear and better
blade flotation over all surfaces.
Your new blade’s steel components are protected with a
baked-on powder finish that resists cracking, corrosion,

VEHICLE MOUNT
FloStat® HYDRAULIC SYSTEM
WESTERN® has designed custom mounts for most
vehicles. Due to differences between vehicle models,
mounts are generally not interchangeable.
Western Products’ FloStat® hydraulic system provides
a fast and uniform speed of lifting and angling. The
system raises the blade in two seconds, and all angling
functions are less than five seconds. For fluid type and
filling instructions, see Fluid Change section in this
Owner’s Manual.
The mount is fastened to the underside of the vehicle
frame and provides the primary connecting point
between the snowplow and the vehicle.
Attached to the mount are two removable receiver
brackets. The receiver brackets are attached to the
mount with lock tabs and hairpin cotters. The receiver
brackets are easily removed to provide even more road
clearance during the non-plowing months of the year.

OPERATION
Function Time Outs
BLADE POSITIONS
Except for the LOWER function, all functions
automatically time out, or stop, after a period of time.
This helps prevent excessive battery drain.
NOTE: For best road clearance during
transport, place the blade halfway between the
straight and Vee positions. The scoop position is
NOT RECOMMENDED during transport.
The RAISE function time-out period is 2.5 seconds,
while all others are 4.25 seconds.
The MVP® snowplow can be used in five basic plowing
positions:
Automatic Shutdown
Straight Blade
If the snowplow control is not used for 20 or more
minutes, it will automatically turn off.
Move both wings to form a straight blade for wide path
plowing or “stacking” snow.
Smooth Stop
The control automatically allows the blade to coast to a
stop. This results in a smoother operational “feel” and
reduces shock to the hydraulic system, resulting in
longer hose and valve life.
Angled Blade
Move one wing “OUT” and the other wing “IN” to form
an angled blade in either direction for general plowing
and widening.

OPERATION
HYDRAULIC SYSTEM
Oil Level
The FloStat® hydraulic unit valve manifold has four
relief valves built in to prevent damage to the snowplow
or the vehicle if obstacles are hit. These valves are
preset at the factory and do not need any adjustments
unless the valve manifold is serviced. When the force
against the blade causes pressure in an extended
ram to exceed set limits, the relief valve opens allowing
oil to escape, and the ram plunger retracts.
Push lift arm all the way down with the UltraMount®
System attached to the vehicle in a Vee position.
Remove the fill plug. Fill reservoir through the fill plug
hole until reservoir is full. Replace fill plug. For fluid

AND ICE
PLOWING SNOW
WARNING
CAUTION
Never plow snow with head out the vehicle
window. Sudden stops or protruding objects
could cause personal injury.
Drinking then driving or plowing is very
dangerous. Your reflex, perceptions,
attentiveness and judgement can be affected by
even a small amount of alcohol. You can have a
serious or even fatal collision if you drive after
drinking. Please, do not drink and then drive or
plow.
CAUTION
Wear a seatbelt when plowing snow. Hidden
obstructions could cause the vehicle to stop
suddenly resulting in personal injury.
Follow your vehicle owner’s manual for driving in snow
and ice conditions. Remember when you drive on snow
or ice, your wheels will not get good traction. You
cannot accelerate as quickly, turning is more difficult
and you will need longer braking distance.
CAUTION
Flag any obstructions that are hard to locate
under snow to prevent damage to product or
property.
Wet and hard packed snow offers the worst tire
traction. It is very easy to lose control. You will have
difficulty accelerating. If you do get moving, you may
have poor steering and difficult braking which can
cause you to slide out of control.
CAUTION
Never stack snow with the blade angled. This
could damage the snowplow or the vehicle
bumper.
Here are some tips for driving in these conditions:
• Drive defensively.
• Do not drink then drive or plow snow.
• Plow or drive only when you have good visibility for

headlamps can light up only so much road ahead.
• If you are tired, pull off in a safe place and rest.
• Keep your windshield and all glass on your vehicle
1. Before plowing, make sure you know of any
obstructions hidden beneath the snow such as
bumper stops in parking lots, curbs, sidewalk
edges, shrubs, fences, or pipes sticking up from
the ground. If unfamiliar with the area to be
plowed, have someone familiar with the area point
out obstacles.
clean to see around you.
• Dress properly for the weather. Wear layers of
clothing. As you get warm you can take off layers.
2. If possible, and you have good visibility, plow
during the storm rather than letting snow
accumulate.
3. Do not exceed 10 mph (16 kph) when plowing
snow.
4. When you are stacking snow, begin raising the
blade as you come close to the stack. This will let
the blade ride up the stack.

OPERATION
PLOWING SNOW (Continued)
Hard-Packed Snow
Clearing Parking Lots
1. Raise the disc shoes so that the cutting edge
comes into direct contact with the pavement.
1. Clear areas in front of buildings first. With blade
raised, drive up to the building. Drop blade and
“back drag” snow away from building. When snow
is clear of the buildings, turn the vehicle around
and push snow away from the buildings towards
outer edges of lot.
2. Use the lowest gear to place maximum power
behind the cutting edge.
3. Use an angled blade or the Vee position to more
effectively remove hard-packed snow.
2. Plow a single path down the center in the
lengthwise direction with the blade in the Vee
position.
Deep Snow
1. Move the blade into the Vee position and make an
initial pass.
3. With the blade in the scoop, angle, or dogleg
position, plow successive strips lengthwise until the
area is cleared and snow is “stacked” around outer
edges.
2. Bite into the edges using only partial blade width
until job is cut down to size for full blade plowing.
Continue to move the snow using angle, scoop,
and/or dogleg positions.
4. If the snow pile becomes too deep for the vehicle to
push, scoop away the edges of the pile until it can
be pushed by the vehicle.
Rule of thumb:
6" of snow – use entire blade width;
9" of snow – use 3/4 of the blade; and
12" of snow – use 1/2 of the blade.
PARKING WITH SNOWPLOW ATTACHED
Experience and “feel” are the best guides.
3. When plowing deep snow, be sure to keep the
vehicle moving.
WARNING
4. Ballast is suggested for maximum traction. Secure
ballast behind rear wheels. Do not exceed vehicles
GVWR and GAWR.
Lower blade when vehicle is parked. Keep 8'
clear of blade drop zone. Temperature changes
could change hydraulic pressure, causing the
blade to drop unexpectedly or damaging
hydraulic components. Failure to do this can
result in serious personal injury.
5. For increased traction, use tire chains where legal.
Clearing Driveways
1. Head into the driveway with the blade angled and
plow snow away from buildings. Widen driveway by
rolling snow away from buildings.
Whenever you park your vehicle, completely lower the
blade to the ground.
2. If the building is at the end of the driveway, plow to
within a vehicle length of the building. Push as
much snow as possible off the driveway.
3. With a raised, straight blade, drive through the
remaining snow to the building. Drop the blade and
“back drag” snow away from the building one
vehicle length. Repeat if necessary.
TOWING DISABLED OR STUCK VEHICLE
DO NOT use any part of the snowplow assembly as an
attachment point when retrieving, towing or winching a
disabled or stuck vehicle.
4. Back the vehicle to the building and plow forward
removing the remaining snow from the driveway.
Check municipal ordinances for disposal of snow.
