This is a really old thread but I thought someone might benefit from this message. I bought a barely used model 4504 14 years ago. I guess the guy who bought it new burned the clutch out almost immediately, got disgusted and traded in for a kubota. I got the tractor with 150 hours on it, put a clutch in it and have been pleased with it. The guy who sells them imports them from china and puts the name allied on them. I have spoken to the guy a few times and i dont trust him at all. But this little chinese tractor has power to spare. For parts i have to go online but most parts are available. I dont think there are any dealers anywhere and if you buy one new, if the guy in ohio still sells them, i wouldnt hold my breath for any kind of follow up service once you buy the tractor. Doesnt sound promising right? But i got a 35 horse tractor with a bucket almost new for $3300. $300 for the clutch... so if you dont mind having to tinker with your tractor, these chinese tractors are very o.k. in my book.
