C. Weight Packages
Adding a front or rear weight package to a tractor affects the weight distribution
per axle as well as the total tractor weight. In addition, the actual weight effect applied to the axle is
amplified by the distance the weight is hung away from the axle center line. The following chart
shows the gross weight of each weight kit and the net result of adding the kit on the front and
rear axle.

Multiply every pound of weight added to the front weight kit by 171% and add this figure to the front
axle. Multiply every pound of weight added to the front weight kit by 71% and subtract this figure
from the rear axle weight. The total effect on the tractor s hould be the sum of the front effect less the
rear effect and should equal the weight added.
Multiply every pound of weight added to the rear weight kit by 118% and add this figure to the rear
axle. Multiply every pound of weight added to therear weight kit by 18% and subtract this figure from
the front axle weight. The total effect on the tractor should be the sum of the front effect less the rear
effect and should equal the weight added.
Multiply every pound of weight added to the auxiliary rear weight kit by 116% and add this figure to
the rear axle. Multiply every pound of weight added to the auxiliary rear weight kit by 16% and
subtract this figure from the front axle weight. The total effect on the tractor should be the sum of the
front effect less the rear effect and should equal the weight added.
