I have an Allis-Chalmers tractor owners manual that I'd like to sell, but the cover is torn off, so I don't have a clue as to what model it is for. It looks like something out of the 60's. The engine (gas or diesel) is 262 cu. in. (3 9/16 s 4 3/8) and the shipping weight is 6300 and 6400 respectively. Looks like a 4-speed trans. with a 2 speed giving 8 forward speeds. In an overhead view from the back it shows the air cleaner mounted horizontaly on the left of the engine with the hydraulic controls to the left of the driver's seat. The Power Director clutch lever is to the right. The tach/hour meter is at the bottom of the instrument cluster. The steering wheel hub cover is square and the fuel tank is sort of tear dropped shape. The manual is a combination owners manual and parts book. Hope this is enough info to identify.
