OPERATION
REAR WHEEL TREAD SETTING
The rear wheels on the RANSOMES CT325 /
CT333 are adjustable from 39 2to 53 in (99 5-134.5
cm) on the standard adjustable rear wheels. Tread
width settings are made on the adjustable rear
wheels by changing the position of the rim with
respect to the wheel disc, by changing the position
of the wheels disc with respect to the axle, and by
interchanging the rear rims. These various positions
are shown in Figure 34.
NOTE: After changing the rear wheel tread setting,
the wheel rim-to-disc nuts and the disc-to-axle nuts
should be torqued to 137-1 59 lbs.ft. (186-215 N.m).
TRACTOR WEIGHTING
To obtain sufficient traction for 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, as shown in Figure 35
through 37, or 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 and increased rolling
resistance and thus higher fuel consumption.
NOTE: When adding weight, adhere to the tire load
capacities. Refer to “Tire Pressure” and the “Tire
Inflation Versus Permissible Load” table on page 27
through 28.

WEIGHTING FOR STABILITY
Front end ballast may be required for stability and
steering control when weight is transferred from the
front wheels to the rear wheels as the implement is
raised by the tractor 3-point hitch.
As a general guide
Ballast the tractor (less implement) so that
approximately 1/3 of the tractor weight is on the
front wheels. For optimum traction, tractor equipped
with FWD should be ballasted 50 40-45% of
machine weight is on front wheels.
When a mounted implement is raised to the
transport position, the front wheel reaction should be
least 20% of tractor weight.
Add additional front end ballast as required for
stability during operation and transport. Tractor
