Abstract
Abstract A cultivator tine mounting includes an elongated support that rotates about a central axis with tine holder holes at each end of the support. The holes are surrounded by upper and lower surfaces which can be configured to seat the upper fastening portions of a tine with securing means, retaining the tine in fixed relationship with the support. A stiffener element or deformation of the support can be located near the holes for additional support. The support can be hollow and made of two sheet metal interengaging parts. Also the tine holders can be vertically extending members that are attached to the remainder of the support.
