I have had Richard's skid plate on for a couple seasons, now. When my 60" deck is fully raised and the PTO engaged the shaft will rub slightly. Richard suggested I adjust the mechanism so it does not come up quite so high. I have never bothered to. Rather opting to simply not lift it all the way up when I cross the gravel drive or disngaging it altogether. I also believe Richrad has redesigned it so as to avoid this, but I could be wrong here.
I also remove the deck all the time to put the Woods BH6000 on and am a pro at this. Once you have the knack, although it is a little tight, its quite easy.
