18mm Iron thresher Spare Parts

A thresher coupling, specifically referring to a tractor-driven thresher, involves connecting the thresher to the tractor's Power Take-Off (PTO) shaft. This allows the tractor's engine to power the thresher for separating grain from stalks and chaff. The coupling typically uses a universal joint and a transmission shaft to transfer rotational power, ensuring flexibility and smooth operation even when the thresher and tractor aren't perfectly aligned. Safety features like a protective guard are often included to prevent accidents.
