WM120P/S — GENERAL INFORMATION
GENERAL
The Whiteman WM-120PM and WM120SM Series plaster and
mortar mixers are shipped completely assembled and have
been factory tested.
The drum batch capacity of these mixers is between 3.5 and
4.0 bags. With proper care, they will give continuous service
year-after-year.
These mixers can be powered by either gasoline or electric
motors. The power from the engine is transmitted via the clutch/
reduction assembly directly to the paddle shaft. Therefore
providing high mixer torque and eliminating V-belts .
