<p>Agricultural machine, especially a tractor, with a mechanically driven front axle of adjustable track, the supporting and driving functions of which are performed by components (104, 120, 120a, 122) which are largely separate from one another in constructional terms and extend separately from one another to the front wheels (110) and the track width of which can be adjusted separately. In two main alternative versions of the invention, the housing (100) for the differential and angular gear belonging to the front drive is either fastened in a stationary manner to the supporting pedestal (70) or else is fastened in the manner of pendulum to the supporting pedestal in a constructionally more or less intimate combination with the axial middle portion (120). This separation of the supporting and driving functions in constructive terms makes it possible to use a standard front axle of adjustable track, as has also been tried and tested for extreme load requirements, especially regarding wheel tread forces for relatively large track widths, especially in the form of square sections with a double perforated strip, in which the sectional pieces can be displaced next to one another and adjusted by means of the perforated strip and corresponding bolts. <IMAGE></p> |
