Rear Hydraulics

[JasonW]

I like the way you ran the hoses from the rear remotes to the diverter. Looks good, hoses look nice and relaxed. Are you controlling the outlets with the switch box that comes with the diverter, or did you go for one of those fancy Control Grip variants?

Using the switch box that came with it. I mounted it near the cup holder under the right side armrest. Tucked out of the way but still accessible. And I got power from the work light circuit.

I hope I am forgiven to ask newbie questions here. I read up a few things already but I am still not 100% clear about what means what.

Is it correct that a rear remote is an electronically controlled valve with a lever as demand generation connected via a cable?

And a diverter valve is an electrically or mechanically operated valve connecting two cylinders to one pair of outputs which are controlled elsewhere?

And a multiplier is bascically a multiple output diverter valve where one cylinder at a time is being connected (typically by a solenoid and switches or pushbuttons) to a pair of hydraulic outputs controlled by a lever or servo valve located elswhere?

A rear remote is a directional control valve used to control a pair of cc remote outlets. May be lever or solenoid operated.

A diverter is typically a 6 port flow conyrol valve that can be used to alternately switch a directionsl control valve between two different cylinders. It may be lever or solenoid controlled.

A hydraulic multiplier is typically a ganged block of outlets with one solenoid valve for each pair of outlets. It is used to switch the outlets back and forth between a single directional control valve. Same as a diverter but with many more outlet ports.

You are mostly right:

A rear remote can be mechanically or electrically controlled, in his case it's mechanical.

A diverter can be mechanical or electrical, in his case it's electrical, and it can be use to supply a path to as many cylinders as needed, that will then be controlled by the first remote valve when selected.

Yes you have the last part right.
A multiplier is a series of dividers

Hello Dan and North Idaho Wolfman,

great, thank you very much for clarifying, confirming !

A bit more info on this question…

There are mechanical valves that can be remotely mounted with the lever actuating the valve through a mechanical cable (think bicycle brake cables)

I might have caused some confusion here so my apologies.

I referred to the multiplier that @JasonW installed as a diverter but that's really because of the way I'll be using the same multiplier. I have the four button Control Grip with momentary buttons which are pressed with the thumb while moving the in cab lever forwards or backwards. In my case only one function is activated at a time i.e. either extending or retracting one piston in one cylinder as the lever is moved while a button is pressed, so diverting oil for that one function. In @JasonW's case, he could extend or retract the piston on as many as one to four cylinders simultaneously by energizing one, two, three or four solenoids, so basically multiplying the output.

From Summit Hydraulics.

"A hydraulic multiplier is a hydraulic diverter selector valve that allows you to easily add additional rear remotes to your tractor. Keep in mind that this isn’t a hydraulic control valve. This means the hydraulic multiplier does not control the fluid in and out of a cylinder (see our manual monoblock or solenoid monoblock valves), only what cylinders will receive the fluid from a control valve already installed.

The switch box control features 4 separate rocker switches which allow you to select circuits 1, 2, 3 or 4 separately or simultaneously. The anodized mounting bracket is fully protected against corrosion and offers quick and easy installation, the industrial-grade enclosure and switch are weatherproofed for durability. A 10ft wiring harness with weatherproof connectors is also included."

Well, no, since a multiplier is really a (multiple) diverter the expression in my humble opinion is correct. I think the multipliers should really be called "diverter with x outputs" but I think it's too late at this stage

The joystick with the pusbuttons looks like a great solution to me, only one hand required and hand can stay on the joystick for all controls.

The main issue with the multi-button aftermarket joystick handles is cost. They are very pricey....

Summit's description leaves a lot to the imagination. Care to diagram the flow through their two valve multiplier when both valves are activated simultaneously? My guess is all outlets are connected in series.

So far I’ve only used it with my box blade. With 2 activated (rippers and top link) both cylinders will move but it go path of least resistance first so they would all be parallel.

In other recent post, I do not have a quick hitch.

So I wanted a maintained on switch for my hydraulic top link so when I’m hooking/unhooking implements I can move the hydraulic top link from the rear of the tractor. Either to line up the top link or to release tension on the lower links.

Thanks. That info would be a useful addition to the Summit description.

In this case I would buy a Mercedes W123 gear lever on Aliexpress for $7 incl. shipping, a set of IP65 rated pushbuttons for just over $10 and do a bit of DIY.

After @MtnViewRanch's recommendation I ordered and received a Scorpion X Series four button control grip and it was $250. "Pricey" is a relative term, and given that the multiplier costs $1,000, and the two necessary hydraulic hoses will be extra, the function, ergonomics and aesthetics of the control grip are worth the added cost to me. Also, I have no need to move two pistons in two different cylinders at the same time.

The black one is shown but I got the nicer, Kubota grey version.

I think that's their job, not mine!

I am surprised at that price - pretty reasonable. I would have expected 2x or more based on other prices I have seen.

I need to make a correction. It was $270 not $250, but still a reasonable cost for the control grip. It came from Canada so prices might be different in the near future. I will say that it's a very nice piece with every part of the kit appearing to be well engineered and well made. When I purchase the multiplier from Summit this spring I won't be needing the switch box.

I must admit i had not given this much thought. So how is the loader valve plumbed into the multiplier?

The control grip posted above will be used on the rear remote lever. Not the FEL lever.

So presumably the joystick buttons are maimtained. Whats the advantage of having the switches on the joystick over the switch box?
