PTO Drive Shafts

Power take-off (PTO) drive shafts are routinely found on machinery such as trucks or tractors where the primary transmission may also be used to run auxiliary equipment. A PTO driveshaft includes ridges or teeth, also called splines, that mesh with the primary driveshaft to transfer torque. PTO driveshafts are usually designed to permit quick connect/disconnect capability.
