I have a CT 440 tractor and the sway bard adjustments are extremely under rated for this model tractor. First of all the connect pins joining the sway bar to the tractor continue to break and or come out. Secondly the whole mechanism is too flimsy for this horse power. Where the sway bar connects to the tractor is currently broke on one side.
You cannot push anything using a box blade in reverse without causing some kid of damage to the sway bars.
