ABSTRACT:
A manual snow removal tool has a blade, a pivotable handle, and a load transfer subassembly for structural rigidity and distributing force applied by a user through the handle to the blade. The load transfer subassembly defines an elongated channel, spaced from the handle pivot mount, through which the handle extends. The handle is slidable within the channel over a range of angular positions. The snow removal tool also has an angle adjustment mechanism for selectively positioning the handle at a desired angular position. The shovel can be used to scoop or windrow snow.
