I'm installing 3rd function this weekend using Summit's kit. I have questions about wiring. I've seen there are different options for wiring - e.g. wiring direct to battery, a keyed/ignition or fused power source. Wiring direct to the battery seems the easiest route. What are the pros/cons of each option? Pretend you are explaining this to a middle schooler (that's about my knowledge of wiring).

I have done 2 summit kits. One on LX and MX. On the LX, I went to key power, with an inline switch. On the MX, I did the same key power, just haven’t installed the switch yet.

What is the benefit of having an inline switch?
I could cut the power the the solenoids if I had the bucket on to not pressurize the lines if accidentally hit. I haven’t done that yet on the MX. I’ve gotten better about not hitting them or fidgeting with them while doing other things. May not put a switch in.

I wired my Summit kit such that I can power off the tractor and then use the joystick buttons to close the grapple lids to relieve the pressure from the grapple hoses. Then I stick the two grapple hose ends together and haven’t any issues getting them back on later. So far so good with the battery—been that way two years.


I used one of these off Amazon to add it to my panel easily:

I used this stuff to carry the wires over without getting rubbed on:

The OP has the tractor as I do so I would just caution to keep this split loom away from the exhaust manifold / exhaust pipe. I use the same thing on my electrical addons and getting to the battery (left side) requires careful routing.

The pic shows two split looms I ran. The orange goes from the battery to the fel pivot then up to a connector I mounted on the crossbar (on strut). The black split loom runs from tha battery back to a small fuse block inside my fender.

There is a spade connector in the fender by the left rear wheel that is live only when the key is on. That is how I wired my 3rd function (not summit, but from everything attachments).

I am wondering if everyone is happy with the summit third function valve . Joebabs everything attachments is a wR long and some of the dealers use this one but cost couple hundred more .

Everything was installed yesterday. The valve from summit is leaking pretty badly, so I've reached out to them about that; but otherwise it was an easy install. Tractor looks mean with a grapple.

I had my last 3rd function installed by the dealer. They wired it into a switched power source.

Summit finally picked up the phone and I ordered what I need.

UPDATE and self-deprecating admission: I installed the solenoid to the valve body with the fiber protection pad on it (idiot!!), then snapped off a bolt in the aluminum valve body trying to over-tighten the bolts to stop the leak. So, chalk the $50 valve replacement up to stupid tax and move on.

On the positive side, I was able to order flat faced couplers to replace the ag couplers on the front side so I don't have to use adapters. Saves me some space up front.

This is my first foray into hydraulics. I've learned a lot.
