Abstract
An angle gear drive for a portable lawn care implement including first and second housing portions molded to net shape. First and second housing portions support an input shaft having a bevel gear and an output shaft having a mating bevel gear. The assembled housing portions include annular ribs for locating and restraining the input and output shafts so that the bevel gears are securely enclosed in a sealed gear cavity. The gear cavity is sealed by an anaerobic sealant. Grease is supplied to the sealed gear cavity through an axial lubrication bore formed in the input shaft along the axis of the input shaft.
