When you split a Farmall 504 Tractor, does the engine (1) remain bolted to the "back" of the tractor and you move the front wheel assemble forward or (2) does the engine stay bolted to the side rails and move forward with the "front" of the tractor? The I&T manual that I have been using is not clear. Or does it matter? With the equipment I have it would be easier to leave the engine with the back of the tractor and move the front wheel assemble forward. This would leave the engine cantilevered out until I can sling the engine and remove it. Is there any special way to sling the engine to lift it? Thanks in advance.
