One thing to keep an eye on with your unit. The front wheel braket is only attached with a couple of sheet metal screws through the housing. One of my screws rattled out, causing the wheel to bend the housing up. I sunk some addiitonal self tapping screws in mine after beating it back into shape...mostly back into shape anyway, lol.
Not sure what engine you have on yours. I've had significant problems with the 10HP Briggs engine on mine. It spit out an exhaust valve seat and then bent the rods somehow 2 years later. I replaced the head. My dealer says the 10HP engine is pretty much crap. I looked into replacing mine with a Honda but that was pretty pricey...would be better off just buying a new unit.
