PRE-OPERATION CHECK

REAR BALLAST

To avoid personal injury:
A For tractor stability and operator's safety, rear
ballast should be added to the rear of the
tractor in the form of 3-point counter weight
and rear wheel ballast. The amount of rear
ballast will depend on the application.
Implement as Counter Weight
6' Box Scraper
Approx. 450 kg (990 lbs.)
Rotary Tiller
Approx. 240 kg (530 lbs.)
Back Hoe
Approx. 770 kg (1690 lbs.)
BLiquid ballast in rear tires
Water and calcium chloride solution provides a safe and
economical ballast. Used properly, it will not damage tires,
tubes or rims. The addition of calcium chloride is
recommended to prevent the water from freezing. Use of
this method of weighting the wheels has full approval of
the tire manufacturers. See your tire dealer for this
service.
