Does the pump also provide flow for the power steering? If not, a simple
pump that delivers 6 or 7 GPM at 2000 psi would be about right. Since
pumps are sold specced as a volume per revolution, calculate what you
need for that flow at the full engine RPM (prob 2600).

I don't know your tractor, but later Ls used a dual pump on the same
shaft for the PS and implement flow. If your machine does that, it will
be more complicated.
