Ford 2003 F-350 Owner's Manual page 149

Book. These instructions are available through your Ford dealer; they
include the list of vehicle models recommended for snowplowing and
snowplow weight limits. Use of the Snowplow Package Option, or its
equivalent, along with these instructions will help avoid possible
powertrain and chassis damage from snowplowing.
The front and rear GAWR, GVWR, Total Accessory Reserve Capacity
(TARC) and tire inflation pressures are found on the Safety Compliance
Certification Label located on one of the vehicle's door jambs. This label
is applied to all vehicles completed by Ford Motor Company. Incomplete
vehicles built by Ford Motor Company will have an Incomplete Vehicle
Label in place of the Safety Compliance Label. The TARC does not apply
to Incomplete Vehicles and will not be shown on the Incomplete Vehicle
Label. The weight of the vehicle with occupants must never exceed the
front and rear GAWR or the GVWR.
The TARC is the weight of the permanently attached equipment that can
be added to the vehicle without violating the vehicle's Safety Compliance
Certification. This includes the snowplow mounting hardware but does
not include the removable portion of the snowplow assembly.
Installing the snowplow
Read the following instructions before installing a snowplow:
• Front GAWR must not exceed 63% of the GVW. Add ballast weight to
the back of the vehicle, if necessary. Refer to the Safety Compliance
Certification Label to find your vehicle's front GAWR.
• The Front Axle Accessory Reserve Capacity and the TARC listed on the
bottom right of the Safety Compliance Certification Label will determine
whether or not the addition of a snowplow will overload your vehicle.
• The weight of the snowplow and supporting components distributed to
the front axle must not exceed the Front Axle Accessory Reserve
Capacity.
• The total weight of the snowplow and aftermarket equipment must
not exceed the TARC.
• The weight of the installed snowplow and aftermarket equipment must
not load the vehicle beyond the GAWR (front/rear) and GVWR listed
on the Safety Compliance Certification Label.
• The total weight of the snowplow and aftermarket equipment must be
considered part of the payload and must not exceed the GCWR for
towing.
• Federal and most local regulations require additional exterior lamps
for snowplow-equipped vehicles. Consult your dealer for additional
information.
