The present invention relates to driving gear assembly for a tractor, which comprises: a hydraulic pump assembly unit which includes a PTO power line which includes an engine-side PTO driving shaft which receives engine power from an engine-side PTO driving shaft rotating by the engine power, and which rotates, and a PTO clutch which transfers the power transferred to a PTO input shaft to a PTO output shaft; a hydraulic pump assembly unit which includes a hydraulic pump driven by the power of the PTO power line; a hydraulic pump driving gear placed on the engine-side PTO driving shaft and the PTO input shaft to rotate with the PTO input shaft; an idle gear linkably connecting the hydraulic pump driving gear and the hydraulic pump assembly unit; and a first ball bearing placed on one side of the hydraulic pump driving gear and a second ball bearing placed on the other side of the hydraulic pump driving gear, as a configuration for coupling the engine-side PTO driving shaft and the PTO input shaft and for suppressing the shaking of the hydraulic pump driving gear. The present invention aims to provide a driving gear assembly for the tractor, which is able to remarkably reduce noise and increase durability.
