TRACTOR PREPARATION
TRACTOR FRONT TIRES - Use front tires of equal
size and maintain equal pressure in each tire. The
pressure of the front tires must be increased to the
maximum approved pressure recommended by the
tire manufacturer to compensate for additional load
placed on the tires with the Front End Loader. See
your tractor Operator Manual. Adjust the front tires to
the widest recommended setting on adjustable mod-
els for maximum stability. Front end weights must
NOT be used while loader is on the tractor.
Observe tractor preparation guide in loader Operator
Manual. Pay particular attention to “minimum tread
settings” information in your Mounting Kit Installation
Instructions.
TRACTOR REAR TIRES - Maintain equal pressure
in each of the rear tires. Use the widest recommend-
ed rear wheel setting for maximum stability.
IMPORTANT: Do not exceed the maximum load
capacity of the tires on your tractor. See Tire and
Wheel Specifications in tractor Operator Manual
