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.
