Spring teeth for a harvesting machine are each constructed of spring wire having a square cross section and being wound so as to define a coil torsion spring section terminating in a tine, with the tine having a leading flat surface, considered relative to the engagement of tine with the crop during pick-up operation, and having a trailing flat surface disposed parallel to said leading flat surface. The coil torsion spring is mounted to a tooth bar formed as a channel member such that the outer surface of the coils make a relatively large area contact with the tooth bar at location spaced approximately 180° from where the tine joins the coil torsion spring. This together with the fact that the contact area of the flat sides of the wire in the coil region is also quite large leads to a damping action that lessens stress in the tooth assembly.

Digging and tilling tools with both a central step and an offset shaft are disclosed. The central step allows a user to apply pressure directly over the centerline of the tool head, and the shaft, offset to one side, allows clearance for the knee.
