American Pneumatic Tools (APT) has introduced a full line of walk-behind power trowels. The new lineup offers three main models to fit a variety of concrete surfacing applications, including:

PT244 — This model features a 24-inch blade diameter, and makes quick work of fine-edge trimming. Weighing in at 132 lbs. and powered by a 3.5-hp Honda GX 120 engine, the unit features blade speed ranging from 40-115 rpm. Available with the standard Twist Pitch, this model offers an efficient way to adjust pitch.

PT375 — Featuring a 36-inch blade and a 4.8-hp Honda GX 160 engine, the PT375 is ideal for everyday applications. It is available with both Twist Pitch and Cog Pitch, which allows the operator to easily adjust the pitch of the blade while surfacing. The unit weighs 192-194 lbs., depending on pitch configuration.

PT479 — For covering large areas, the PT479 is an ideal trowel solution thanks to the 46-inch blade. Equipped with an 8-hp Honda GX 270 engine, the PT479 can reach blade speeds of up to 115 rpm. Also available with the Twist Pitch and Cog Pitch functionality, the PT479 has an operating weight of 227-229 lbs.

Featuring two adjustable pitch options, each trowel comes equipped with foldable devibrated handles, a robust steel palm trigger, a maintenance stand, and the QuickStop safety feature.

Conventional trowels can spin up to 540 degrees after the motor is stopped. With the addition of QuickStop, APT trowel’s blade rotation is immediately halted after a zero-degree handle spin. Without shutting off the engine, the QuickStop function allows for speed adjustment without belt or clutch damage.
