TOW’s four walk-behind trowels have several features to improve operator comfort, control and flat finishes.

The four-blade Honda-powered trowels are offered in 36- or 46-inch diameter guard rings with power options ranging from 5.5 to 11 horsepower.

Two trowels with 36-inch ring diameters are available — the lightweight SCT36H55 and SCT36H80 — weighing 166 and 188 pounds respectively. Each trowel has a rotor rpm of 60-125. A 5.5- horsepower gasoline engine powers the SCT36H55 model while an 8-horsepower engine drives the SCT36H80. Both models can finish 7 square feet of concrete per revolution.

The 46-inch ring diameter SCT46H80 and SCT46H110 Stow trowels are designed for larger, more challenging applications while still allowing the operator to maintain complete control with optimum comfort from start to finish. Both models feature rotor rpm of 60-125 and weigh 211 and 224 pounds respectively. An 8-horsepower engine drives the SCT46H80 while the SCT46H110 uses an 11-horsepower engine. Both trowels have the capability to finish 11.5 square feet of concrete per revolution.

All four Stow trowels come fitted with the standard handle with a star wheel for precise adjustment. An optional quickadjust handle with a tensioned lever mechanism can be added. To improve user safety, all handles feature fingertip throttle control and a durable centrifugal safety switch that automatically stops the trowel should the operator lose control of the handle.

Additional features on Stow concrete trowels include: cast aluminum gearboxes with cooling fins; large tapered bearings and high oil capacity to reduce heat and ensure cool operating temperatures; onepiece hardened worm gear and bronze composite drive gear for unmatched durability and performance; a spider hub composed of high-quality class-35 cast iron and hardened spring steel wear plates to eliminate wear on the thrust collar and reduce maintenance costs.

Ingersoll-Rand’s WT-Series walk-behind trowels have quick-change blades and precision controls. The WT-Series models are built to work in a variety of applications, including driveways, floors, foundations, concrete patch repairs, sidewalks, walkways, and slabs.A wide variety
Ingersoll-Rand’s WT-Series walk-behind trowels have quick-change blades and precision controls. The WT-Series models are built to work in a variety of applications, including driveways, floors, foundations, concrete patch repairs, sidewalks, walkways, and slabs.

Five trowel models are offered: WT2440H, WT3055H, WT3655H, WT3690H, and WT4690H. These trowels are manufactured with a screw pitch control that adjusts the blade angle to produce a flatter end product. A quick-release safety lever stops the trowel instantly, providing the operator total control on every jobsite. Each trowel is constructed on a heavy-duty steel frame to provide a solid platform, resulting in smoother finishes.

Each unit is equipped with a four-cycle Honda engine. These engines run quieter, use straight gas and are more fuelefficient than two-cycle engines. Each engine is solidly mounted to the trowel frame, to prolong engine life.

The centrifugal clutch on the WT-Series is designed to engage smoothly. The gearbox is configured with high-quality bearings and double-lip seals. These features minimize gearbox maintenance. The trowels are also constructed with three guard rings that provide extra machine stability and safety to the operator.

Several options are available on the walk-behind trowels: a 36-inch float pan, quick-change combo blades, quick-change finish blades, quick-change float blades, and a two-wheel trowel dolly.

The HoverTrowel is a very light power trowel that is capable of changing its pitch during operation. Created for use on polymer-modified systems, its weight range is 35 to 45 pounds. This weight dramatically reduces swirl and chatter marks.

The HoverTrowel can be modified in many ways for use on epoxy quartz, natural stone, terrazzo, aggregate-filled polymer- modifieds, cementitious urethanes, microtoppings, color hardeners or just plain concrete surfaces. “It’s a power trowel that also does things that a man can do,” says Drew Fagley, president of HoverTrowel. “It’s sort of a hand trowel standing up.”

The design of this trowel makes it easy to change from various rpm and torque loading pneumatic motors to a 4-cycle engine. The standard extension handle doubles in length at 6- inch increments. A selection of options is available, from multiple motors along with gas and pneumatic handles, various blades and float options. Blade, float and pan options come in two sizes to be used with the interchangeable guards. This design feature allows the trowel to be set up for 25- or 34-inch trowel paths. Plates and pins can be attached to the guards for additional weight.

Broadcast or Troweled Quartz Systems: Which is Right For Your Job

When it comes to resinous quartz flooring, there are two basic ways to approach the installation. You can broadcast the quartz onto a floor coated with wet epoxy, or you can mix the epoxy and quartz together -- making what is often called epoxy mortar -- then trowel it on.When it comes to resinous quartz flooring, there are two basic ways to approach the installation.

Like an artist's paintbrush on canvas, the trowel can create a wide variety of effects on overlays.

Sometimes there's no better way to finish a cementitious topping than to get down on your hands and kneeboards and go to town with a trowel.
