Hydraulic Pump Question

I suppose an alternate may be to replace the 3-pump unit with a single of appropriate size.

I'm kind of lost and will appreciate any input or referrences.

On another topic, by your handle we have similar tractors. I have an MF20 that lived its life as a fairway mower. It had a Ransomes mower on it and was well maintained until somebody noticed a "banging" under the seat and they used that as an excuse to purchase a new mower (small po-duck golf course). It turns out the banging was the hydraulic pump relief valve operating normally. I paid them $500 for the tractor/mower.

Know anybody that wants a 12' wide, 7-gang reel mower?

The wheels and the blade lift (not used now) are driven from the hydrostatic pump directly off the engine. The former reels were driven from the auxillary belt-driven pump controlled through an electric clutch on the engine. I don't know what the relief is set at.

In reading around it looks like I'll need to measure/calculate the pulley sizes for the deck drive and the three driven shafts in order to guestimate the HP/RPM needed.

The engine and drive systems work fine.

My father-in-law, whose failing knees prompted him to give this to me (I have 3 acres to mow), had built a combining manifold for both the supply and return lines (3 each). Whatever motor he adapted to the deck turned, but very slowly and un-usable.

He is an old-school seat-of-the-pants mechanic and does not do math. He suggests that I just mount an auxillary engine to the deck and get to work, but I'd prefer to be a bit more integrated (and quiet) with it.
