Hydra-lectric or regular hydraulic control?

I have a super 77 with hydraulic control for one cylinder. It also has fusible connections in the instrument panel which look to be for a hydra-lectric system. How does one tell if it is a hydra-lectric or just a normal hydraulic control set-up? Also, is there an easy way to tell if the unit can both lift and provide down pressure to implements or if it is just able to operate one-way cylinders?

For hydra electric you need a oliver hydra e. cyl. and connecting cable. wire will come out of unit ahead of lever. good idea but too much messing around. cables only lasted a short time before they were pinched or torn off. always use two way (2 hose) cyl. on Oliver hyd.

Bob, the unit is capable of providing either single-acting or double-acting hydraulic power. On the bottom of the reservoir near the floor you should see hoses plumbed in. If you see only one hose going in on a side, it is in the single-acting setup. If there are two hoses plumbed in on the side, then you have a double-acting setup. To tell whether or not you are set up to use the Hydra-Lectric feature, look directly behind where your control lever enters the housing. You should see one side with a cover plate-the side which also does not have a control lever. If you see a cover plate on the side corresponding to the side that you have a control lever on, you are not set up for Hydra-Lectric operation. If, however, you see a solenoid mounted directly behind where the control lever enters the housing, you have the Hydra-Lectric option. Since it is a Super 77, the system, if it is present, should be as described as above, a System 3 Hydra-Lectric. If, by some remote chance, the unit has been replaced by a previous version of the hydraulics such as seen on earlier model Fleetlines, it will be different than described above, for it will be a System 1 or System 2.
