Bought a Troy Bilt front propelled mower back in Mar 07. The belt kept falling off. The grass would get thrown up through a hole, knocking off the belt. I'd take the mower back and they would give me another belt. After the 3rd time, I wanted to return the mower. But the supervisor reassured me that if the mower had problems, they would take care of it. I removed the cover to the belt area so the grass had somewhere to go and not clump up that would kick the belt off. By Sept 07, I made the discovery that the mower should have came with a shroud or baffle that prevents the grass from accumulating around the belt. You could see the lightbulbs popping on above these small engine mechanics, "yeah sure, we got those, we'll order one and put it on for you". And of course, they did, for free plus a $25 Farm & Fleet gift certificate. Well, that solved the problem until the Spring of 2011, the $50 warranty expired, when the baffle dislodged, was chewed up by the mower blade and pinched the belt above the main pulley. Took it back for repaired and explained the history of the belt problems, how I made the discovery of the missing baffle, how I wanted to return the mower but was talked out of doing so and told that I would be taken care of if there was ever a problem. The last repair took 3 weeks so I gave them 3 weeks, called and they tell me the parts (the new baffle just came in. They had it on that afternoon and they did all the work and part for free. Get it home to a job site, that's right, I mow for a few yards and the front self propelling does not work. It was damaged when the baffle fell off and they never tested to mower to see if everything was working. I also notice a part missing from the transmission assembly (TA) which will cost $100 to replace but it's the 4th of July 4th so I'll need to wait to take it back. There's something in the TA that's not engaging. I removed a wheel to see it's gear which is attached to the wheel shaft which runs through the TA. I can see why it's $100 part. What a mess! Without the front wheel propelling the mower is not easy to push around. It's a heavy mower. Will report back on what they will do. If they don't fix it then I'll have to junk it but they said they would take care of me or it.....
