RIDING TROWEL HAVING ROTORS CONFIGURED FOR REVERSE ROTATION
A self-propelled power trowel for finishing a concrete surface is equipped with reversible rotors to allow an operator to reverse the direction of rotation of rotor blades. The trowel includes a rigid frame adapted for operation over a concrete surface, a pair of rotor assemblies having rotor blades tiltably connected to the rigid frame for frictionally contacting the concrete surface and supporting the rigid frame thereabove, a prime mover mounted to the rigid frame and operatively coupled to drive the rotor blades of the rotor assemblies in opposite rotational directions. Synchronous or hydraulic motors are configured for causing, responsive to manual controls, reversal of the direction of rotation of the rotor blades.
