In response to Barnyard's earlier comments.The M bolster was broken and welded,the side rails were welded to the bolster as well. The Md radiator is junk,so using the 400 radiator as I don't want to spend a lot of money on a new radiator. the MD flywheel was stolen,so the 400 flywheel.I needed a hydraulic reservoir,hence the 400 reservoir.The 400 came off a dairy.Their loader tractor. it is rough,it has had the liveing crap beaten out of it.The motor was rebuilt(with a new clutch) shortly the transmission went south.The TA had been out for years,a rear axle was wallered due to a rear wheel being loose for a long time.Something poped in the rear and it quit.A rear wheel is cracked,smooth tires.then it sat for 10-15 years.The MD sat on the side of a mountain at 9500 ft for 40 years. So we are going to have a hodge-podge.I really don't care,as I'll have a running tractor instead of two junkers in the 'dead row'.
