Not sure I agree about the tires. Many of them have 16.9x38's and 18.4x34's on the rear. 9.5x15's on six-bolt rims are the most common fronts, while many have 10x16's on 8-bolt rims. Your hydraulic numbers are wrong, too, The hitch and auxillery valves are supplied by the 12 gpm pump. I want to say that this system was originally equipped with an 1800 psi relief valve, but it may have been a 2000 psi valve. Bigger and later tractors could have 2200, 2300, and 2500 psi relief valves, which will screw right into an 856, so the only way to know what you've got is to get it on a flow-rater. The MCV pump (steering, TA, brakes, and lube is supplied by the 9 GPM pump. The PTO unit had the 3 gpm pump. Here are some other specs- 42 gallon fuel tank, 1000 RPM single shaft PTO unit or 540/1000 dual-shaft unit (most common), one or two hyd vavles, fast hitch or 3-point. There was also a 856 Custom, basically a stripped-down 856 to compeate with the JD 4000. These have a 37 gallon fuel tank, a single element air cleaner (no inner saftey filter), and only one headlight in each fender.
