Surface finishing trowels, systems, and methods thereof
A trowel 40 for finishing a concrete surface comprises blades (50 figure 2) configured to finish the concrete surface. A pitch angle is defined between the blades and the concrete surface. The trowel has a frame 43 with a motor 39 coupled to the frame. The motor rotates the blade about a first axis (14 figure 1). A fork 45 is pivotably coupled to the frame about a second axis 46 such that pivoting of the fork about the second axis changes the pitch angle. An actuator 60 is coupled to the frame and operable to pivot the fork. An input device 81a-b is operable to control the actuator to thereby change the pitch angle of the blades.
