ABSTRACT:
A machine for cultivating the soil has a main transverse beam carrying a transverse tool shaft, and a gear box for driving the tool shaft. The beam has a frame for attaching the machine to the conventional three-point hydraulic system of a tractor, the tractor power take-off shaft then being connected to drive the tool shaft via the gear box. To enable the machine to be constructed in various widths and to facilitate its assembly and transportation, the main beam is in two half portions interconnected by the gear box housing. Likewise the tool shaft is in half shaft portions driven by a common, hollow gear box drive shaft. The gear box itself is formed in upper and lower portions, the upper portion of which is interchangeable with a different gear ratio portion to suit different tractor power take-off speeds. The gear box drive shaft has a rearwardly projecting drive shaft portion for driving further equipment to be used in combination with the machine.
