Pop's 88 and Super 88 had the system on them. Never used it cause he always used pull-type plows back then. Our 1650 4WD had the system on it. Used it with a 575 auto reset 5 bottom plow and it worked really slick! You dropped the 3-point hitch, hit the remote lever and forgot about it. The hydra-lectric system was a very good system that was years ahead of it's time. Both the series 2 and series 3 hydraulic systems were pretty dawg-gone good systems for their day, too. We used the Super 88 on a stone picker and it was the only tractor we had that could shake the pickup head fast and hard enough to do a good job of shaking the dirt through the tines before dumping the rocks into the hopper. Trouble is all that bouncing of those heavy stones (the pickup head was 4 ft. wide and we used to pick up boulders that would barely fit in the head) on the picker head would blow the pump seals periodically and dump the hydraulic oil into the tranny. However the tractor worked so good on the stone picker and it was a fairly simple matter to pull the pump and change the seals, we continued to use the super 88.  The hydraulic systems on our 1355, 4010 and 4020 were totally worthles for that application.
