For sufficient traction and maximum performance in
heavy draft operations, and to counterbalance
rear-mounted equipment, weight should be added to
the tractor in the form of liquid ballast, cast iron
weights, or a combination of both. Only enough
weight should be added to provide good traction and
stability. Adding more weight than is needed results
in unnecessary soil compaction, increased rolling
resistance, and higher fuel consumption.
When adding weight to the tractor, tire
pressures may need to be increased. Refer to the
Tire Inflation Pressure chart found in this manual.
Front end ballast may be required for stability and
steering control when weight is transferred from the
front wheels to the rear wheels as an implement is
raised by the tractor three-point hitch.
Ballast the tractor (less implement) so that
approximately one-third of the tractor weight is on the
front wheels. For optimum traction, tractors equipped
with front-wheel drive should be ballasted so that
40-45% of machine weight is on the front wheels.
When a mounted implement is raised to the transport
position, the front wheel reaction should be at least
Add additional front end ballast as required for
stability during operation and transport. Tractor front
end ballast may not always maintain satisfactory
stability if the tractor is operated at high speed on
rough terrain. Reduce tractor speed and exercise
caution under these conditions.
When using front-mounted equipment, add weight to
the rear axle to maintain good traction and stability.
Front-mounted equipment varies in weight. Refer to
equipment manual for ballasting.
The weighting limitations that follow are limitations
only. They do not imply that the tractor should be
weighted to attain the weights given. Use only
