OPERATION
Adding Rear Weight
IMPORTANT: The stability of the machine varies with different attachments, tractor options, terrain and
operator’s driving technique. Install weight at rear of tractor to provide adequate machine stability.
To determine the additional rear weight required, pick the tractor model, header model and size to find
your “base machine”. Add up the values for the base machine plus options/conditions to obtain a score for
a particular application. Go to the "score" column to determine which weight packages (if any) are
required.

NOTE: For scores of 235 and higher with the 9352** tractor only, score may be reduced by having
an authorized tire dealer install calcium chloride fluid in the rear caster tires as follows:
• To reduce score by 60 points: Install 250 lbs. (115 kg) in each 11 x 16 or 16.5 x 16.1 caster tire.
(This is the maximum allowable for 11 x 16 tire.) Fluid can not be added to the 7.5 rear tire.
• To reduce score by 100 points: Install 400 lbs. (180 kg) in each 16.5 x 16.1 caster tire
IMPORTANT: To prevent structural damage to walking beam and casters, do not install fluid in caster
tires on 9250/9350* model tractors.
