Concrete finishers can now complete their jobs in less time and with superior results.

The new 4-blade B and J Series walk-behind power trowels from MQ/Whiteman feature more powerful engines to generate improved rotor speeds of between 60 to 155 rpm for smoother, faster finishes.

The four new B Series models, with 46-inch (1,170 millimeters) ring diameters and six J Series models, (36-inch, 914 mm) also feature an ergonomic throttle control, lifting bail, and rugged spider assembly for extended life. Refined engineering delivers optimal balance for exceptionally smooth finishes. 

Technicians will benefit from a new access panel, standard on all B and J Series walk-behind trowels. This simple panel makes it easier than ever to grease the unit, change blades, and service trowel arms, trimming service time and difficulty common while maintaining other trowels.

The trowels also include a height-adjustable 2-inch (50 mm.) diameter tubular steel handle for improved operator comfort and workability and a unique throttle control design features detent settings for easy selection of the operating speed. A centrifugal shutdown switch protected by steel housing provides superior durability.

Both B and J Series models are available with MQ/Whiteman's patented Quick-Pitch or standard handles for greater leverage as well as adjustable handle heights for improved comfort. The Quick-Pitch handle design enables the operator to react to changing concrete conditions by quickly raising or lowering the blade pitch in 1/8-inch (3.2 mm.) increments. Other contractors prefer the standard handle for infinite blade pitch control.

The ten new walk-behind trowels are offered with Honda and Robin engine options, ranging from 5.5 to 11 horsepower.
