Well, here's some more information on the used tractor- I saw it today. It's being sold by a dealer after he rented it out for two summers to one organization. He's checking to confirm maintenance history. He estimates about 45% tread remaining on front tires and about 85% on rears- he attributes this to lots of turning on concrete surfaces. Tractor has some dings and dents that really surprised me given the reported usage- I guess when it's not yours you don't care?!? Lots of paint scrapes also. It wouldn't start so dealer said it needs to be charged. Opinions and price/concession ideas?
