Wow. Not sure what the problem is but I hate to hear this. We got TT's and like them well. I've got 1500 plus hours on mine and had to replace a wheelmotor and Hydro pump. Does this qualify it as a piece of junk? No, just something that does bad. Just replaced the inside bearing on the Impeller on the bagging unit. Does this make it junk? No, just another part that failed. Scag is an excellent mower and would buy another in a heart beat. If anything, I'd wished they would redesign them to weigh less.Royalslover said:Have any of you guys had trouble with vibration coming from the pto shaft? My brother and both have a tt and we have had nothing but trouble. He actually had the whole back of mower fall off.
