Agricultural Machinery Lower Fork
Agricultural machinery lower fork (also known as 3-point hitch lower arm fork, traction lower fork) is a core force-bearing component of the tractor 3-point hitch system. Specifically designed for various agricultural machinery field operations, it is mainly used to connect the tractor rear axle with agricultural implements (plows, rotary tillers, harrows, seeders, etc.). It undertakes the key functions of traction power transmission, implement loading, lifting adjustment and shock absorption, directly ensuring the rigidity and operation stability of the agricultural machinery hitch system, and is suitable for various farming, sowing and harvesting scenarios of light, medium and heavy-duty tractors.
Material: Full series of ductile iron QT450-QT600, accurately corresponding to American Standard ASTM A536: QT450-10 equivalent to ASTM A536 65-45-12, QT500-7 equivalent to ASTM A536 70-50-05, QT600-3 equivalent to ASTM A536 80-55-06. The material is tough, wear-resistant, fatigue-resistant and impact-resistant, which can effectively resist the load impact caused by field bumps and soil resistance, not easy to deform or break, and is suitable for the harsh working conditions of heavy-load and long-time continuous operation of agricultural machinery.
Adopting precision casting and CNC precision machining technology, the fork body is designed with double fork arms and reinforcing ribs, with uniform force and outstanding rigidity; both ends are precision bored, equipped with wear-resistant bushings, which are flexible in rotation, small in wear and easy to assemble and disassemble; the surface is treated with anti-rust, resistant to field sediment and rain erosion, with long service life. It has strong compatibility, can match mainstream tractor models around the world, supports customization of fork length, hole diameter, mounting hole position and non-standard structure according to customer needs, and the quality strictly complies with ASTM standards, suitable for foreign trade export, with stable supply and reliable quality.
