A towed implement includes apparatus adapted for being driven by a power take-off shaft of a towing tractor. The implement includes a tongue having a hitch bracket at its forward end, the bracket incorporating a ball coupler. A hitch adapter is provided for coupling the hitch bracket to a three-point hitch of the towing tractor, the adapter including a hitch bar connected to the ball coupler by a pin. The implement includes a power transmission assembly separate from the hitch adapter and including identical first and second right angle gear boxes, with the first gear box being rigidly fixed to the tongue and the second gear box being drivingly coupled to the first gear box along an axis passing through the ball coupler and about which the second gear box may rotate. The second gear box has an input shaft coupled for being driven by the tractor power take-off shaft and a steering arm is coupled to the second gear box and has an end received in a guide track fixed to the hitch adapter so as to keep the second gear box input shaft aligned with the tractor power take-off shaft.
In an agricultural implement requiring power to be delivered thereto by a towing tractor and including a tongue formed by an elongated beam, a hitch adapter connected to a forward end of the beam and providing connection points for attachment of a tractor three-point hitch, and a power transmission assembly mounted to the forward end of the beam and including a first part fixed to the beam and a second part rotatable relative to the fixed part about a vertical axis and including a horizontal input shaft adapted for connection to a tractor power take-off shaft, the improvement comprising:
In an agricultural implement requiring power to be delivered thereto by a towing tractor and including a wheel-supported frame, a tongue coupled to and extending forwardly from the frame, a transmission having a housing mounted to a forward portion of the tongue for rotation about an upright axis, and an input shaft journalled in the housing and being adapted for connection to a tractor p.t.o. shaft, the inprovement comprising:
