Yep, but I have a push-pull feeder and gun for my MIG too. I just rarely use it.

Took today's working hours to get the valve mounted and plumbed, and I'm still not thrilled about how I got it done - but FF only has so many fittings. It'll work until I integrate this valve into the main hydraulics. Right now it's plugged into my rear SCV and my top link is unplugged.
Ran out of light when I got it all buttoned up, but I did fire up the PTO and check the wheel for visible run out via flash light - didn't see any. :)
Tomorrow we grind!

That grinder looks awesome. Thanks for sharing the build with us.

It's Sunday. I haven't even gone outside yet. ;)

Well, it worked... :)
The clutch was slipping and then I was putting the full force of a 3.5" cylinder against a stump without cutting it - as Foggy predicted, the pillow block broke.
So I'll remake those into bushing blocks out of steel and get back to work.
One maple almost gone.

I will say, the greenteeth cut beautifully.

This was the last pass.

Wow. I'm pretty impressed with the cut your taking there. :D
Lotsa force applied via those cylinders.....and quite a bit of shock loading at times too. Easy to abuse your tractor with those forces at play. I did break one of my drag links (lift arms) on my three point once. I think I can attribute that to my stump grinder. Go easy....I think you have an aluminum housing on that rear axel of your tractor......and not sure how much lateral force it can handle?

Cast iron tractor. ;) The 5's aren't built light. It's not a kubota. :p
I'm getting ready to roll home or I'd do the math. Engine RPM was about 2k, gear box is 1.46:1 (increase). 540 rpm PTO at 2400 engine (no ePTO).
I'm going to do some flow control to slow the swing. Feathering it wasn't enough.

Stumping is one of the hardest things you can do to a saw. It's murder on it's clutch, the bar, the chain, and the crank.
Had the pillow block not broken across the mounting ears (through the sides of the bolt slots), this stump would've been gone after 2 passes. There's no evidence of any wear on the teeth.
I'm going to replace the pillow blocks with bushing blocks like I should've done from the start, probably put a flow control in the sweep cylinder, tighten the clutch, and get back to destroying stumps. :)

I like the idea of flow restrictors in the cross feed. Just washers can provide the needed restriction. I've seen some adjustable, needle valves that look pretty neat too. Kinda wondering if a crossover relief valve - like that used in my snow plow build - would be a solution for a tyro operator like you. ;)

I have a couple of high pressure dial-adjust one way restrictors (full flow the other direction). One's 3/4" NPT and the other is 1/4". I have less than $15 in both of them. :D I just don't know if I want to go that route or with a needle valve, or get one of the pin hole one's like they have at FF. FF didn't have any of the hose lengths I needed in 1/4" or I would've done the whole thing in tiny hoses.

657 rpm or so is what I came up with. So 2063 SFM at the edge of the wheel at 2K engine RPM.
