Three point linkage (or three-point-hitch) is a standardised system to attach implements to tractors. They comprise of three movable arms assembled in a triangle or 'A' formation, and are controlled by the hydraulic system allowing lifting, lowering and tilting. Three point linkage systems are designed to shift the weight of the implement, such as a plough, to the tractor providing the tractor more traction. The top link (upper centre arm) is adjustable in length to allow the attachment to run at the desired level. In most instances, the top link will also actuate the tractors built in 'draft control'. Draft control is a system that adjusts depth automatically when resistance.
With this mode you can make your Japanese Small tractor Yanmar Ke-3 much more useful and attach any agricultural attachments & implements- backhoes, blades, buckets, bush hogs (mowers), harrows, and hole drillers!
The orientation of the implement can be altered longitudinally by adjusting the 'levelling box' and laterally by adjusting the top link. Stabilisers can be fitted and adjusted to reduce implement 'sway', normally to avoid the implement fouling the tyres when traveling.
