A three-point hitch is a linkage system that allows ploughs or other devices to attach to an agricultural tractor. A three-point hitch consists of several different components, including a hydraulic system, lifting arms, stabilisers and linkage points. Each hitch has a series of attachment holes that allow a variety of implements to be attached to the tractor. The main purpose of a three-point hitch is to transfer the weight of the implements (as well as any items the implements are moving) to the rear wheels of the tractor, which are larger and have a greater load-bearing ability than the front wheels.

Hydraulic piston

Attach each of the hydraulic pistons to either side of the tractor's engine block using two of the 8-inch steel screws and the Phillips-head screwdriver. These pistons will serve as the hitch's lifting arms.

Fasten each of the 4-foot-long cylindrical metal bars to the inner clamps holding the tractor's rear tires. Use two of the 4-inch steel screws and the Phillips-head screwdriver. These cylindrical metal bars will serve as the three-point hitch's stabilisers.

Fasten each of the 5-foot-long flat steel bars (with bored holes in the centre) to the tractor's rear axle using two of the 4-inch steel screws and the Phillips-head screwdriver.

Fasten the free end of the hydraulic pistons and the stainless-steel linked chains to the centre holes in the 5-foot-long flat steel bars. Use the final two 8-inch steel screws and both of the steel washers.

Insert the power take-off driveshaft into the outlet valve of the tractor's engine. The power take-off driveshaft should slide smoothly into the engine's outlet valve.

Secure the free ends of the stainless-steel linked chain to either end of the power take-off driveshaft using two of the steel eye bolts and the adjustable ratchet.

Attach the 3-foot-long flat steel bar to the end of the power take-off driveshaft using two of the 4-inch steel screws.

Fasten the free ends of the cylindrical metal bars and the 5-foot-long flat steel bars to either end of the 4-foot-long flat steel bar with the 11 bored holes, using the two lynch pins and the hammer.

Secure the free end of the 3-foot-long steel bar to the centre of the 4-foot-long steel bar using the remaining two 4-inch screws. The 3-foot-long steel bar, which is attached to the power take-off driveshaft, should line up perfectly with the centre of the bored steel bar at the end of the three-point hitch.
