Diverter Sanity Check

[Fallon]

Look at me quoting my own post.

So I picked up the snowplow as described. Technically it "works". Diverter button down, left is left right is right. However, right takes an eternity. This makes sense as this is the direction that the cylinder is fighting itself.

I'm going to keep it as is, but I foresee myself swapping this diverter to the lift circuit or abandoning the whole thing and going true 3rd in the long run. Overall I'm pretty disappointed with this lesson.

Learning is priceless. And you shouldn't be out to much, you can reuse most of that setup except for some fittings, maybe some hoses when you move over to the lift circuit. Lord knows I've made more expensive learning opportunities in my career & hobbies.

Pretty much. I'll do my best to share my experience with others considering a similar setup. I'm sure in the long run I'll be happy and it will work out. I need to look into what it would take to swap to the lift circuit. I think the motion would make sense for the grapple with forward to close. The plow would be a bit silly but I'm sure I'd adapt fast enough.

I used the diverter more today with the Grapple and I'm starting to wonder: Is the regen dump (grapple close) circuit just as powerful as the non-regen curl (grapple open)? My grapple "works", but I'm not sure it has the closing/pinching force it should.

Regen connects both ports on a cylinder. That way fluid from the rod side can go to the cylinder side when the bucket & load are essentially pulling the bucket down really fast on their own. Otherwise loose seals would let in air. As the cylinder side surface area is greater than the rod side (rod side has a rod on it taking up space) the greater surface area lets the cylinder side overpower the rod side. Faster movement with significantly less power is the net result.

I'm assuming your grapple cylinder would be extending to close, which would be affected by regen rather than opening. I'd assume fast (regen) open would be kind of beneficial as I can't think when you'd need a strong open, but you would obviously want a strong close.

Not Sure how You Feel about OEM Look , But rather than swap out or remove everything , What about a After market Single Joystick or even 2 or 3 Joystick Loader Valve ? After putting in the time , Money You have in this project , I Would Ditch the " Look " and get a loader valve that fits My needs .

Thinking something like this :

3 SPOOL 25 GPM JOYSTICK LOADER VALVE W/GRAPPLE

Just My :2cents:

Fred,

There's just now way on earth that monstrosity would integrate even remotely nicely to my machine.

I'd sooner just convert what I have to a true 3rd function.

That's where my confusion lies. There is nothing fast about how anything operates in the dump (regen) direction on the diverter. The grapple closes pretty slowly and seems like it has little clamping power. The snow plow angles right super S L O W L Y.

during your lever-right, push past the first detent, then it's the same pressure/force as lever-left.
In the first lever-right detent, you are applying pressure to both sides of the cylinder. One side of the cylinder has a bigger area, so more force, so it'll move. However, if you push farther right, you will only have pressure on one side of the cylinder (the same yet opposite of lever-left).

That'd be nice, if my loader valve was that style. No detents here. Always regen.
