ABSTRACT:
The low-profile, lightweight tiller of compact, uncluttered design is adapted to be rigidly mounted upon the rear, powered lifting links of a garden tractor so as to be raised and lowered by the latter between transport and ground-working positions. Driving power for the transverse rotor of the tiller is obtained by a direct drive connection with the power takeoff shaft of the tractor. A right angle gearbox located inside the open bottom housing for the rotor is supported by the rotor shaft itself and has an upwardly and forwardly directed input shaft that connects directly with a telescoping, universal joint drive line connection with the power takeoff shaft. A special telescopic construction of the rotor allows the same to be adjustably shifted through the gearbox in order that the rotor may be selectively laterally offset with respect to the tractor wheels, and the rotor housing is sectionalized such that opposite end sections thereof may be detached from one end of the central section and added onto the opposite end section to properly house the rotor when the latter is likewise offset.
