I'm looking at an old M600 that has a blown wisconsin v4 motor. The old farmer bought it when it was a couple of years old and used it up until 2-3 years ago. it's rough and will need a lot of TLC, but he's got a ripper bar on the back, a backhoe that mounts to the front lugs, standard bucket, and forks for the machine. I'm looking to use this around my farm for general digging and road maintenance. Am I just buying a headache? I'm worried that I should just buy a newer small machine and add the attachments as I go. Any ideas what this would be worth considering some seal kits, and a few hoses that will surely be leaking? He's at 3800, but I'm pretty sure he'd come down as his other option is probably doing a lot of work to haul it to a scrapyard for the 4 tons of scrap weight. He mentioned doing the heads twice on the engine, but thinks the problem was worse the last time it died. I'm guessing a complete teardown and possibly a broken rod. If it weren't for all the useful attachments he's got, I'd probably pass on this and spend the money on a 520 i've also been looking at that is running, but only 19 HP kohler gas motor. thanks for any opinions!!
