On a related note, if your terrain is hilly, you should consider substituting the top link with a piece of chain. If you stick with the top (fixed) link, you can bend it or something else if you drive through a valley. If the tractor is going up one side while the mower is still going down the other, you're creating a V shape (as seen from the side). Well everything is rigid to keep everything flat. Something has to give and it's often the top link.
If your mower has sliders for the top link point, you "should" be OK but again, if you're on hills, watch those slides to make sure they're not hitting the limits. If they are, consider the chain.
