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 PS-150C can be ballasted
with sand, water, steel or a combination
of each. These three components provide varying
weight capacities, allowing the machines
to be tailored to specific requirements.
Weights (approximate)
Operating weights include lubricants, coolant, 80 kg (175 lb) operator, full fuel tank, full hydraulic system, half-full water tank
and ROPS.

Ballast Compartments
Ballast compartments are positioned with
a calculated balance of wheel to weight
ratio. Internal-frame baffles help prevent
surges when water ballasted.
Sand and steel ballast can be added
through large cover plates on the
operation deck and water can be added
through a fill port.
When adding water, it is recommended
that only the primary ballast chamber be
used because it is sealed.
Sand and steel ballast can be removed
through a bolt-on side cover and water
ballast can be emptied through a drain
port.
