PURPOSE:To make a machine body higher at a paddy field where it is desirable to raise the machine body as high as possible and make farming work performable without entailing any damage to crops on a ridge in a field, by installing a front axle case detachably in an inclined shaft case direct or via an auxiliary case. CONSTITUTION:A driving shaft 1 is horizontally built inside a center case 2 installed in a front lower surface of a tractor body, and an inclined shaft case 5 is screwed in both end pars of the case 2. A front axle 14 is supported on a front axle case 15 with bearings 16 and 16, while the front axle case 15 is turnably and insertably fitted in a vertical supporting part 5a in the lower part of the case 5 via a bush 20. Under the condition of a paddy field, in order to make a machine body higher, a cylindrical receiving part 28 of an auxiliary case 25 is inserted into the vertical supporting part 5a, while a bush 33 and a trust bearing 34 are annexedly installed therein, and the front axle 14 largely drops as much as a portion for H after alteration. |
