Just bought an Allis Chalmers 712 hydro yesterday. $300 runs great new battery tire chains and a plow. Any problems I should be aware of anything to watch for? Also I want a deck for it, will any simplicity deck from that era fit cuz I see a complete deck (42") for sale for $100. Will any 700 ac/7000 simplicity series deck work on my machine? I will post some pics when I get the chance. These old garden tractors are awesome!
