A final drive for an agricultural vehicle has a casing (10), a wheel shaft (12) supported in the casing by means of two support bearings (16,18) spaced from one another along the length of the wheel shaft (12), an input shaft (20) rotatably supported in the casing (10) with its axis parallel to but laterally offset from that of the wheel shaft (12), and a bull gear (26) connected to the wheel shaft (12) by means of a splined coupling (30') disposed between the support bearings (16,18) of the wheel shaft and having external teeth (32) meshing with teeth on the input shaft (20) to transmit torque to the wheel shaft (12) from the input shaft (20). In order to reduce wear on the gearing of the final drive, the splined coupling (30') between the bull gear and the wheel shaft is spherical. |
