MQ Whiteman B46H90 Specification

Pioneering concrete finishing
since 1939.

WALK-BEHIND TROWELS

MQ Whiteman power trowels have been at the center of
the concrete finishing world since 1939. Our commitment to
innovation and development enables us to offer the industry’s
premier line up of concrete finishing equipment.

Top quality components. Concrete contractors demand reliable

equipment to get the job done right. The MQ Whiteman gearbox uses a heat­treated worm gear and composite bronze gear to ensure that your machine
isn’t sidelined during a critical job.

Low cost of ownership. Our spider assembly uses high-strength wear

plates made of trowel steel to prevent wear on key components. Repairing
your trowel shouldn’t be costly so we make certain our replacement parts are
priced right.
