Recently acquired a Ford A64 wheel loader. New to me so need some expert advice. The loader starts and runs great. When it’s shifted into drive or reverse it will not move. Fluid levels are good. Wondering if there’s a disconnect shift mechanism to disengage the transmission for towing? Thinking it’s in tow mode and the linkage is malfunctions so it won’t reengage. Anybody out there have access to an owners manual or service manual they can share?
