Allan: Most new tractors that came into our area, came equiped with the biggest volume pump that could be ordered. Looking back, I expect this was driven by the potato industry. I did not buy my 656 new. It was bought new by a potato farmer, and I acquired it when I bought his farm. It had holes drilled in the right flat top fender. It was also equiped with two remote valves, one plumbed to rear and both plumbed to sides for front mounted potato cultivator. I asked about the holes in fender. He mounted a special valve bank on the fender and pluged it into one of the remotes on tractor for operating his potato harvester. I never saw this set up as the potato equipment was all gone by the time I bought the farm. I think he told me this valve bank was 5 spool valves, 2 of which had priority for hydraulic motors.

From this I knew my 656 had a 17 GPM pump as he told me it took that volume to operate the potato harvester. I also had this confirmed as I had to replace the pumps on both 560 and 656 during the life of the tractors. IH parts man told me they didn't even stock the 12 gallon pumps, as he wasn't aware of one in the area.
