I am wondering if the suspension seat will fit onto my 2001 Exmark Lazer HP. How hard is it to mount? How much do they run generally? Are they really worth it from what you have heard? I have a couple rough lawns and dont like to get "kicked" in the back like I am with the standard seat I have now. After 8hrs on the thing, I'm a little sore, not too bad, but I wish it could be better.
