Ballast & Weight Information
Rather than weighting the tractor down to pull
heavy loads, try reducing the load. Pulling a lighter
load at higher speed is cheaper and more efficient.
Liquid ballast should never be added until a deter-
mination is made for the need, however, there may

be times when it is desirable to weight the tractor to
decrease slippage and increase balance or stability.
Use no more ballast than necessary, and remove
ballast when it is no longer needed.
Liquid Weighting Valve Level (75%) Table
The following table provides data on the filling of front and rear tractor tires with calcium chloride
solution, based on 75% fill or approximately valve level. The table is based on the use of Type 1
(77%) commercial calcium chloride flake. If Type 2 (94%) calcium chloride flake is used, reduce
the "Lbs. CaCl2" weights in the table by 25%.

To extend tire life and avoid excessive wear of drive
train components, avoid continuous full load opera-
tions at ground speeds below 3.5 mph (5.6 km/h).
There are many factors that affect traction and
balance that need to be considered before adding
liquid ballast; such as soil conditions and/or topo-
graphy, draft load of the implement or equipment
being used etc.
Desirable tractor static weight distribution is approxi-
mately 40 percent of the weight on the rear axle and
60 percent of the weight on the front axle. If it
becomes necessary to add liquid ballast for better

traction or stability, this ratio should be maintained
in all drawbar applications. When dual wheels are
used do not add liquid ballast to the outside dual
tires.
NOTE: If 3-Pt hitch or PTO equipped, it may not be
possible to achieve a 60-40% static split.
Desirable wheel slippage should be 10-15 percent in
average conditions. This slippage rate is important
in order to gain the optimum tire and power train life.
If liquid ballast is required, ballast to 60-40 percent,
which will result in approximately 50 percent weight
distribution under load. For example: if 4000 lbs of
weight is to be added, the 60-40 percent static
weight ratio must be maintained. Do not exceed the
maximum warranted vehicle gross weight for Agri-
culture or continuous duty drawbar usage.
When using liquid ballast, use a solution of water
and calcium chloride to prevent water from freezing.
Where freezing temperatures never occur, plain
water can be used, but the weight added will be 20%
less than calcium chloride solution.
Where anti-freeze protection is needed, use 3-1/2
lbs of commercial calcium chloride flake per gallon
