Abstract
An agricultural tractor has a special drive device mounted on its gearbox, so that with the normal drive disengaged, the tractor can be driven at very low speed. Inside the gearbox is mounted an auxiliary shaft (10) in line with the main drive shaft from the motor, and parallel to the output shaft (6), which has a sliding pinion (18) mounted on its splined end so as to engage an auxialiary drive wheel (28) acting through the differential gear (12, 47). This auxiliary shaft (10) has at its other end, a set of gear wheels (17, 26) driven by a hydraulic motor (20) mounted at its end. The auxiliary shaft carries a pinion (14) which meshes with a gear wheel (11) mounted on a layshaft (13) underneath. The hydraulic motor (20) is driven by the hydraulic pump of the tractor.
