Ballast Considerations
and Ground Contact
Pressures
The most common method of changing
ground contact pressure is to vary the
tire pressure. Another means to change
ground contact pressure is to alter the
ballast. The ballast compartments are
positioned with a calculated balance of
wheel to weight ratio. Internal-frame
baffles help prevent surges when water
ballasted.
The ballast blocks provide a low center
of gravity, resulting in good stability.
The ballast blocks are positioned in the
bottom of the mainframe near the center
of the machine.
Water System
The pressurized water system is
efficient and reliable. The system
includes stainless steel distribution bars
located over the front and rear tires and
retractable cocoa mats for each tire.
The pressurized system includes triple
water filtration and a powerful Cat
water pump. Cat water pumps are
designed to provide long life.
A polyethylene water tank is located at
the front of the machine on the
operator’s platform. A water level
gauge is on the tank within easy sight of
the operator.
