ABSTRACT:
A disk support bracket assembly including a cross tube bracket and a disk shank support bracket pivotally connected to the cross tube bracket to allow the disk support bracket to pivot between a working position wherein the bracket bottoms against the cross tube bracket, and a storage position wherein the bracket is offset vertically from the cross tube to increase clearance. The shank support bracket is pivotally connected to the cross tube bracket near an upper forward corner of the cross tube and includes a relatively wide stop portion that bottoms against a mating stop portion at the front face of the tube bracket when the shank support bracket is in the working position. A pin is selectively insertable through apertures in the brackets adjacent the stop to lock the shank in an upright working position. As the disk is operated in the forward direction, the load on the disk supporting shank urges the stop portions together to bear substantially all the shank loads in the stop area so that forces on the pin and pin wear are reduced over that encountered by a normal load-bearing pin.
