ABSTRACT:
Disclosed is an agricultural implement for cultivating about trees and vines. The implement includes a frame that mounts four gangs of disc blades, two forward and two aft. The disc blade gangs are relatively movable to set up a variety of discing patterns and the gang can be so mounted on the frame that the lateral extensions of the frame do not extend above the height of the disc blades.
