Tractor Linkage Pins Tractor linkage pins are essential components used in the three-point hitch system of agricultural tractors. These pins secure implements such as plows, harrows, cultivators, and trailers to the tractor's lift arms and top link, enabling safe and stable towing and operation. Made from high-tensile steel and often zinc-plated or powder-coated for corrosion resistance, linkage pins are available in various sizes and categories (Cat 0, 1, 2, 3) to fit different machinery. Designed for durability and easy installation, most pins come with linch pins, clips, or chain retainers to prevent accidental detachment during field operations. They are critical for maintaining reliable and efficient implement connection in farming, landscaping, and utility applications.
