Claims18
A rotary tiller tine assembly comprising a main shaft having an end, means on said end of said main shaft defining a key having diametrically opposite flats, a shaft extension having opposite ends, means defining generally rectangular socket portions at each of the opposite ends of said shaft extension, one socket portion engaged with said diametrically opposite flats of said key on said main shaft end, a plug member including means defining a key having diametrically opposite flats with said flats engaged in the other of said shaft extension ends, and an outboard tine including means defining surfaces therein generally complementary to and interlockingly engaged with said flats of said plug member key.
In a rotary tiller tine assembly comprising a shaft and tines coupled thereto, the improvement in which the shaft includes means at an end thereof defining a key, said tines each have a hub comprising a flat strip and means in said flat strip defining a keyway complementary to and interlocked with said shaft key, flat washers disposed on opposite sides of the tine hub, said flat washers also including means defining keyways complementary to and interlocked with the shaft key, and clamp means clamping the washers against the tine hub whereby the washers re-enforce the tine hub.
In a rotary tiller tine assembly comprising a shaft and tines coupled thereto, the improvement in which the shaft comprises a main shaft section and an extension shaft section, said main shaft section having an end and means on said main shaft and defining a key having diametrically opposite flats, said extension shaft section comprising a hollow tube and including means defining a generally rectangular socket portion at one end of said tube and interlocked with the main shaft key, and elongated coupling member extending through the hollow tube, and attaching means interconnecting the opposite ends of the coupling member to the main shaft and to the end of the hollow tube.
A rotary tiller assembly comprising a main shaft, an elongated shaft extension in axial alignment with and extending from said main shaft, said main shaft and said shaft extension arranged generally end to end, means defining diametrically opposite flats on the end of said shaft adjacent said shaft extension, means on the end said shaft extension adjacent said shaft defining a socket generally complementary to said main shaft end and said socket interlocked with said flats so that said extension rotates with said shaft, a tine disposed at said end of said shaft and including means defining surfaces in said tine generally complementary to and interlocked with said flats on said shaft so that said tine rotates with said shaft, and means for releasably clamping said shaft, shaft extension and tine together.
