Abstract
A cultivating implement to be carried by a vehicle comprises a frame (10) having spaced and opposed members (11, 12) between which a tine-carrying bar (13) is supported for gyratory motion the direction of which is counter to the direction of forward rotation of the ground wheels of the carrying vehicle and which derives from and is centered on the axis of axially-aligned stub shafts (14,15) adapted to be driven from a prime mover and supported in bearings mounted in or on said opposed members of the frame. Preferably the mutually-opposed ends of the stub shafts (14, 15) are cranked in mirror-image fashion and the tine-carrying bar (13) is supported between bearing arrangements (28, 29) centered on the crank arms. The angle of presentation of the tines to the ground is preferably selectable to accord with the nature of the work to be done and the tine sweeps or shovels to be used therefor.
