Farrar helped redesign this gearbox/axle assembly for a zero turn lawnmower company to improve performance, increase its operational life, and improve its manufacturability. Farrar produces every part of the assembly including the housing, the internal gears, and the axle and wheel hub (with the exception of the bearings and bolts) and has delivered over 250,000 of the assemblies directly to the customer ready for installation on their assembly line.
