ABSTRACT:
Tilling apparatus disclosed has a rotor shaft with axially spaced multiple tine and hub assemblies having hoe portions of adjacent tines overlapping one another. The apparatus is constructed as a central section and has wing sections pivotally connected to the central section. A first pivot axis for each wing section is the same horizontal plane as the rotor shaft. A first link connects at its lower end to the wing section at the first pivot axis and at its upper end to the central section at a second pivot axis. A thrust link driven by a two-way cylinder moves the wing section about the first pivot axis and then about the second pivot axis. Each tine hub is made in two half-bodies supporting two tines at 90 degrees, with a recess to turn adjacent hubs 30 degrees to one another. Each tine has a bevel on the outer side and a smooth hard surface on the inner side. A drive train coupling power to the rotor shaft has cross drive shafts with extensible and retractable telescoping sections, a chain coupling between each cross drive shaft and the rotor shaft, and a shock absorbing shear pin coupling inclusive of flexible members between an input hub and an output hub.
