This stabilizer spring controls lateral movement of the lower links in the three-point hitch assembly. It sits between the lift arm and the stabilizer bracket, maintaining consistent link spacing during implement operation. A sagging or broken spring allows the lower links to drift sideways, causing uneven implement alignment and increased wear on the hitch pins and bushings. This original AGCO part is manufactured to the same wire diameter and coil count as the original assembly, so it restores the correct preload force without requiring shimming or bracket adjustment. On installation, inspect the stabilizer bracket for elongation at the spring seat and replace if worn.
