Hi , I've got a 2013 BCS 722 tractor that I bought new and use almost exclusively for garden tilling. I say almost because when I bought it there was a deal to get a second attachment at a discount so I got the BCS Bio100 and I used it when new for about a dozen hours until yesterday when I wanted to get rid of some branches from a recently cut tree. After connecting to the tractor it worked fine for about 10 minutes then stopped chipping. I cleared where I thought it might be jammed without success, then disconnected the PTO to assure there was still power (there was), reconnected, still no go, checked the belts and pulleys on the chipper and they all turn with the PTO engaged, but the drum and knives don't move. I'd appreciate any thoughts you might have as to what the problem is.
