I've read a few old threads but im a bit confused. I'm considering buying an older higher hour dyna VT. It really will only be a back up machine that if I was being honest I dont need but at harvest time an extra set of wheels is handy. Is there anyway of identifying if a VT is on its way out? I'm looking at few different tractors all around 10,000 hours. I just get the feeling if I get a good un there is no reason why it couldn't be a very cheap tractor, a bad could be a bottomless pit!!!
