The PTO Alignment Wrench is used to rotate PTO splines for alignment between machines. This allows workers with upper extremity impairments to rotate the tractor splined PTO shaft more easily to align with the equipment driveline. Without such a device, it can be very difficult to rotate the driveline on larger equipment to hitch it onto the tractor. The one shown here can be used for both a 540- and a 1,000-speed PTO. A 1.75-inch version is available for larger sized PTOs.
