Abstract: A split spacer ring that is connectable to a cutterbar PTO drive shaft and works in conjunction with an anti-wrap shield to reduce the effects of crop debris accumulating on the drive shaft. Radial removal of the split spacer ring allows the anti-wrap shield to be axially displaced to enable sufficient telescoping movement of the drive shaft to disengage an end from a rotary cutterhead connection and thereby remove the drive shaft or other cutterbar components for repair or replacement. Improved axial clearance provided by the removed spacer ring also facilitates installation and removal of a crop conveying drum that may be installed on the drive shaft.

Abstract: A pump support coupler assembly for connecting a large displacement hydraulic pump to a tractor power take off device is provided. The pump support coupler assembly includes a coupler housing with front and back walls, and sidewalls. The high displacement hydraulic pump attaches directly or indirectly to the coupler housing back wall. A shaft extends longitudinally through the coupler housing. The shaft is coupled to an input shaft of the hydraulic pump at its first end and a power take off output shaft at its second end. A torque restraint strap extends between the coupler housing and a tractor drawbar, and prevents the coupler housing from rotating about its longitudinal axis. In this configuration, the power take off output shaft supports the pump support coupler assembly and the hydraulic pump, and since the pump is attached to the coupler housing, the pump input shaft is not subjected to bending-type loads.
