ABSTRACT:
A power tool includes a motor having a first shaft, a transmission mechanism operatively connected to the first shaft, a second shaft operatively connected to the transmission mechanism, a housing enclosing the transmission mechanism and adapted to contain a quantity of lubricating grease, and a grease propeller rotatably disposed within the housing on at least one of the first and second shafts for circulating the grease within the housing. A blade may be operatively connected to the second shaft. The transmission mechanism includes a first gear operatively connected to the first shaft, and a second gear operatively connected to the second shaft, where the second gear operatively meshes with the first gear. It may be advantageous to dispose the first and second gears in such a manner so that distance between the blade and the second gear is larger than the distance between the blade and the first gear.
