I had a client needing to move this tractor so I took it in trade. I have not done any research on it yet. It appears it will be in the 40 to 50 HP range. It is a gas tractor, rear and mid hookups, chains, draw bar attachment, near new rear tires, fronts look good. I knew the last two owners and they both like the tractor. Parking brake linkage needs some oil, its rusted tight. That is the only issue I see. First $3500 gets it. The tractor is in SW Madison County https://www.tractorhouse.com/listings/farm-equipment/for-sale/22902937/international-504 Link is for similar tractor. 515-two two nine- zero681 call or text or email the address below.
