I bought a "farm pro" 6"
chipper through Tractor Supply. It looks like a Jinma painted yellow with a different sticker. To me it looks like all these imported chippers are the same, possibly with some mods done by the distributor. Quality control is an issue. Bought the
chipper, set it up and there was banging in the housing. Inspection showed numerous problems. I returned it and, knowing what I was getting into, had them order me another one. Better Q.C. on this unit. I have had this for 2 years now and it works pretty good. Chips softwood no problem up to 4-5". Anything bigger strain my 22HP PTO. I wouldn't go with the 8". I've still had some issues. The drive system for the feed roller had to be fixed. My shaft on the gearbox bent, pillow block housing on flywheel bearing cracked and, IMHO, the emergency stop set-up is garbage. If you buy it (and use it) expect a lot of maintenance time. If I had it to do over, I probably would have spent some more money and got a
chipper that was better quality. I never have enough money to buy the product I want, but down the road I'm always saying "why didn't I spend a little more". Just my 2 cents.
