Picked up an old MM model Z tractor at auction yesterday nice old tractor built in the late 30's hadnt been started in several years. came with 2 new rear tires the auctioneer had mounted before the sale. Tractor has been converted to propane but I found the original Gas tank. Put some propane in the tanks and fired riight off. Had a friend of mines son drive it 20 miles home. I picked up the culivator for it that mounts under the tractor. Sad part is he had all the implements for the tractor. The tractor had been on the farm since new. I didnt have anywhere to keep the other implements. A scraper bought them to sell for scrap.
