Pull the head and oil pan. Tow the tractor away from any building and pour kerosene or diesel on top of one piston at a time and set it on fire. Make sure you remove anything flammable. Be sure to remove the rod cap on piston you're going to heat. Take a piece of 2 X 2 oak and a big hammer and tap on the connecting rod and see if the piston will move. You may have to heat them more than once. The heat should free them. You probably need to rebuild the engine with new new sleeves and pistons and have the crankshaft measured for wear. I did a Farmall A back in 1975 that had never been sheltered and the engine was stuck. I gave $100.00 for it and the 16-inch moldboard plow. Had to replace just about everything on the tractor. Hal
