<p>The soil cultivation or other similar machine has at least one active member drivable at different speeds via gears. It has a shaft sliding in one or more gears, so as to select different running speeds. It can have axial external splines running for part of its length, engaging with internal ones on the gears, which can be mounted next to and touching each other, the innermost surfaces or their splines fitting closely on one or more external shaft surfaces. Bearings in the gearbox for the gears can locate them in the axial direction.</p> |
