A mulch tiller or similar implement having a rigid frame supporting a plurality of forward trash-sizing gang assemblies and rearward plow tools. Spring brackets rockably support the gang asemblies for independent vertical movement with respect to the frame and maintain a generally constant down pressure of the gangs against the soil. The frame includes diagonal beam structure and a lower subframe assembly for compact shipping, good draft load distribution and underframe clearance. Common depth control, main frame and hitch components are utilized for implements of varying widths to reduce cost.

Tillage implement and improved gang assembly therefor

To create a compact package for transport and storage of a foldable agricultural implement such as a field cultivator or the like, a pair of hydraulically operated 180.degree. fold hinges of different heights connect the outrigger frames to the ends of the main frame of the implement. The hinges lift the outrigger frames up and sequentially stackfold one on top of the other in generally parallel relationship above the main frame.

Stack folding outrigger system

A twisted shovel, for a chisel plow or similar implement, having a concave twisted surface. The concave surface maintains soil flow in the desired path as the shovel is moved forwardly through the soil. The soil displaced by the shovel is directed more effectively by the concave surface to one side of the shank to improve crop residue flow and incorporation, and the concave shape significantly improves the bending strength of the shovel over that of flat-twisted shovels of comparable width and thickness.
