Abstract:
An integrated, zero-turn, hydrostatic transaxle, comprising:a first casing carrying a first hydraulic pump driven by a first input shaft and a first hydraulic motor drivingly linked to a first axle shaft, the first hydraulic pump being in fluid communication with the first hydraulic motor to transfer a motive force received via the first input shaft to the first hydraulic motor to drive the first axle shaft; a second casing carrying a second hydraulic pump driven by a second input shaft and a second hydraulic motor drivingly linked to a second axle shaft, the second hydraulic pump being in fluid communication with the second hydraulic motor to transfer a motive force received via the second input shaft to the second hydraulic motor to drive the second axle shaft; wherein the first casing has a plurality of first bosses and the second casing has a plurality of second bosses each adapted to engage a corresponding one of the plurality of first bosses when the first casing is fastened to the second casing, each of the first and second bosses having an opening for accepting a fastener used to fasten the first casing to the second casing; wherein the first casing has a first flat surface and the second casing has a second flat surface adapted to engage the first flat surface when the first casing is fastened to the second casing; and and wherein the bosses and the flat surfaces are arranged to extend outward from their respective casings to create an area of space between the first casing and the second casing when the first casing is fastened to the second casing.
