Benefits of Replacing Worn Top Link Balls
Worn top link balls can allow excessive movement between the tractor and implement, accelerating wear on the linkage assembly and reducing implement stability. Replacing worn components restores the correct fit, improves hitch performance and helps maintain accurate implement alignment during field operation and road transport.
Installation Tip
Inspect the top link eye, implement pin and retaining hardware before installation. Replacing worn pins or damaged linkage components at the same time will maximise the service life of the new top link ball and help maintain correct hitch geometry.
