Ballast required in the rear
The minimum load on the rear axle must be 45% of the basic weight
of the tractor. With a machine mounted in the front power lift the
minimum required ballast (in lb) in the power lift behind the tractor is
calculated as follows:
If the calculated value is negative no additional ballast is required.
The calculated value must be less or equal to (<) the permitted values.
The front and rear axle loads must be greater than the minimum load
of the front and rear axles respectively.

If you have access to a weigh bridge with sufficient measuring range
the total weight and the front and rear axle load can also be
determined by weighing them.
