Our Chief PTO Gear pumps have an internally splined 1 3/8 rod diameter with a thru-drive feature, available in 6 tooth or 21 tooth designs. These gear pumps feature self-adjusting wear plates on each side, high tensile cast iron end plates, roller bearings and two outlet ports with a plug to seal an unused port. The Chief PTO Gear Pump slips onto the tractor PTO, so no gear box is required.
