I bought a 'nice' crapsmen 21" with a 5.5 HP Honda, BBC, etc., etc. at the start of this year (because I had store credit to be used at sears). This is also before I was fully aware of the POS that I was really buying. It was their best model of 21" they carried at the time - a $500+ mower. Engine was great, mower had lots of nice features, etc. Literally by the 4th or 5th lawn that I had used it on, the transmission started slipping in one of the wheels. Had to push the mother#*^%#% around within a couple of hours of use! Why do I bring this up? It uses the same transmisson as your mower (AYP crap I believe). I've seen the mower you have, and if it had a decent transmission, it would be a steal - the engine alone is worth about $250. Your mower is also rebadged as Cub Cadet Commercial, Troybuilt, and probably others. I have since become 'aquainted' with this particular transmission on several other mowers that I've seen on other mowers - Yardman, Sears, Husqavarna, etc. The easy way to spot mowers with these transmissions is the lever used to engage the transmission on the handles. My grandpa also bought a crapsmen with the same transmission, and had the same problems within a few mowings. My sister has a Yardman with this transmission, and the plastic gears in the wheels to engage the transmission have stripped out. Blah, blah, blah. Yeah, they are POS. I have since bought three mid 90's Toro Recyclers (aluminum deck), used homeowner models, for about $150 for the 3 of them. They are very good mowers for homeowner models, and they have a GOOD transmission in them. Find a couple of these used, or buy a Proline Toro.
