The Economy Series Walk-Behind Power Trowel is intended for concrete finishing jobs that do not require the power of larger walk-behind power trowels. The power trowels are lighter than those found in the Pro Series, and are available at a lower price. The E-Series is available with both 36-in. and 30-in. dia. rotor configuration, and is powered by a 5.5-hp Honda engine. The power trowel uses Allen Premium Finishing Blades, which have been manufactured to high tolerances to prevent deformation during finishing. Other features of the E-Series include twist-pitch blade adjustment and a handlebar-mounted safety kill switch.
