I found a B6000E on craigslist with a Woods MMM for a good price but it needs a block. The guys says it had water in the oil and the block is cracked. Before I check into it more where would I find an engine or block for it? I think it has a ZL600 engine. I found some B6000's on auction time from $2500 on up to 4k or more. Are these tractors really worth that much?
