Question about Kubota Third Function Valve Operation

[Milo]

To have a Grapple is worth the learning curve of controlled use.

Thanks for the encouragement, and tutorial ovrszd. I didn't really understand how a diverter worked. But I can foresee it being useful having the ability to curl down while opening a grapple.

Like Richard, I use a true third function on my grapple and have no where near the hours operating he has, but found it easy to learn to use by just tapping the toggle.

Good to hear. Maybe it varies somewhat between the different size and type grapple as well?

The restrictor devices are the best you can hope for. And they work fine if properly used. Just be careful about pinching down the flow too much.

I don't use restrictors on my Grapple. It used two 2"x8" cylinders. My M9540 has considerable flow. They can be slammed open or closed. If I'm wanting to be gentle I can "tap" the joystick buttons and regulate it pretty well. Just takes practice.

To have a Grapple is worth the learning curve of controlled use.

For clarity, understand, a diverter system uses your "curl" function on the FEL to operate the Grapple. So it has delicate control by a steady hand on the joystick. What you sacrifice is the ability to do both functions at once.

The system we're discussing here is operated by electric over hydraulic valves. They only know "open" "closed". The gain is multiple simultaneous functions.

Again, you get the use of 3 multiple functions with a true 3rd function only if you operate the loader joystick properly. People need to be realistic about their capabilities, many people simply do not have the touch that it takes to operate 3 functions at once.

How many cylinders.
Size of said cylinder-s
GPM of the tractors hydraulic pump.
Engine RPMs

Lots of variables alter the operating characteristics of any one item.

May be, I am relatively new to grapples, second year. James and Richard wore me down in spite of my vast experience telling me I didn't really need one.

Now I preferred my pallet forks and three healthy men with chainsaws, but when they grew up they scattered like quails, so love the grapples, I now have one on the 5740and one for M8540.

I agree Brian. I run a road grader with 9 levers plus a steering wheel and gear shift lever. Multi-tasking comes easy to me.

Sorry about the added financial burden James and I put you in Larry.....

Ah, but my old back sure appreciates it Richard. Besides that, like you, my wife is a retired gummit worker and is rich. :laughing:

She must have worked for a different gummit.
