The power take-off, or PTO, shaft on a tractor is the main component that operates the implement that the tractor is pulling. A typical PTO is attached to a drive shaft that is hooked up to the gear box of the tractor implement. When the PTO is engaged, it will turn the drive shaft attached to the implement, which will then turn the gears inside the gear box. The gears inside of the gear box will then operate the tractor implement.
Back the tractor up to the implement. Ensure that the PTO shaft on the back of the tractor is positioned near the end of the implement's drive shaft yoke. Leave the transmission in gear and turn the engine off.
Place the wheel chocks in front of both rear wheels and behind both rear wheels.
Inspect the yoke on the end of the implement's drive shaft and the PTO shaft itself to determine if the PTO connection is a steel-pin connection, a bolt groove connection or a push-pin connection. Most all typical PTO shafts will be designed to connect to the steel-pin drive shaft yokes, bolt groove drive shaft yokes or the push-pin drive shaft yokes.
Turn the end of the implement's drive shaft yoke so that the splined grooves inside the yoke line up with the splines on the PTO shaft. Slide the drive shaft yoke straight onto the PTO shaft with your hands until the locking mechanism of the drive shaft yoke matches up with either the hole or the groove on the PTO shaft.
Insert a steel pin with a cotter pin through the drive shaft yoke and the PTO shaft or insert a bolt through the drive shaft yoke and the PTO shaft. Bend the cotter pin with pliers or screw a nut onto the bolt and tighten the bolt and nut with two open end wrenches. If the drive shaft yoke has a push-pin, push inward on the pin while sliding the drive shaft yoke onto the PTO shaft. Once the push-pin reaches the designated groove, the push-pin will pop back out and lock in place.
