Attempted Grapple Destruction

[MinnesotaEric]

I was gonna suggest that this video looks like an average day at Eric's!!!!:laughing: Matt

To EA's credit, their original, lighter wicked root grapple has held up just fine on my NX!

Try ramming a tree on the outside tine while going about 5 mph. I accidentally did this and it bent my grapple. How much are you paying for that job opportunity? I'd probably do that for 75 cents an hour.

What video are you guys talking about? Is there a Yougottubed link?

Here it is if you haven't found it yet. https://youtu.be/_wle8iv4VhA

:shocked:
Please!! No!! The last thing Ted needs is more ideas for destruction.
I'm not worried about the grapple, but I don't think that poor tractor can take much more. :laughing:

Hmmmm. All the monoblock valves I have bought new to use as tractor AUX valves (Cross, Prince, Energy) came with RVs, except for
OEM. The latter all were integrated into the tractor and had usually difficult-to-access IN and PB connections. Stack valves required
adding the RV as an option, as you say. My own Kioti replaces the system RV with the one in the OEM loader valve if it is installed.

I don't know why you say an RV installed before an FEL valve will cause a problem. It will be redundant if the FEL valve
has it's own RV (they usually do). Only the one set lower will work, of course. Any AUX valve can be protected by
an upstream RV, so another one is not necessary unless the AUX valve requires a lower RV setting. Then you will want one
on its IN port line.

You may need to look a little closer.
If you put your AUX after the pump...1st in line....and it is set at 2500 PSI....then start operating your grapple. All of the fluid is going to the grapple. The return fluid is continuing to your loader valve.
Now, consider that your grapple is doing work.....It is using 2,000 pounds of pressure to clamp the lids, and the fluid continuing to your loader valve is now using the power for the grapple and you have only 500 PSI left.
When the relief valve in the loader valve is met at 2,500 PSI, you will be backing up pressure to slowly meet the relief valve in your loader, which will feel sluggish and weak when operating the grapple.

It just doesn't make sense to put an AUX valve before a loader valve, which contains the correct pressure that your tractor is designed for.
The only way multiple reliefs work well is if the relieved pressure is dumped to the reservoir, resulting in multiple returns and allowing only one system at a time to work properly. Stacking relief valves causes more problems than you think.
I've done this for years and have blown multiple lines by stacking relief valves in series.
Nothing works completely as it should when stacking multiple relief valves.
Can I word it any differently?

It was an accident. I was driving through one of my trails it the woods. I had to make a sharp turn and I didn't hardly make it.

Yes, I think so. : The aux before the loader valve blocks the flow to the loader valve while in operation ... until relief if equipped.

,,,Im surprised the original guy didnt damage his pump.

How mad were you when this happened. I see the spent shotgun shell on the floor.

Another reason for a narrow grapple.

Revisiting the background story of the video, in case anyone missed it...........

We told a local customer that he could take delivery of this grapple in 3 weeks after product testing, but he started calling us every day wanting it sooner. Finally, we just let him have it, intending to make another for testing.
Since he was local, we knew we could fix any problems that may arise. The customer installed it on his tractor, and bent a cylinder in less than 10 minutes.

We were expecting to see abuse, but the grapple had no signs of even being used. We installed a new cylinder and hooked it to our new L6060 Kubota.
The customer came along with us to some property located a few blocks away from work to unleash the fury and see if the cylinder or grapple would fail.

The customer returned home with his grapple, satisfied that it must have been a bad cylinder.....but......he bent another in less than 10 minutes. We then figured out that the aux. valve installed by his dealer was plumbed wrong.
The pressure line from the pump was going straight to the aux. valve with no relief, resulting in tremendous, infinite pressure until something breaks... pump, line, valve, cylinders. It should have been plumbed to the power beyond, which has pressure relief built in via the loader valve. His dealer is coming out today to re-plumb the valve correctly.

Fast forward to this morning..........

I just talked to the customer. His dealer came out, determined that the AUX 3rd function valve was plumbed to the PRESSURE line instead of the POWER BEYOND, fixed it and now it is working PROPERLY!!!!

I told him thank you for letting us use your grapple for testing and GRAPPLE ON!!! :thumbsup:

This is all I have to say about that:

Coincidentally, the grapple in the video will be forever perched on the front of a NX6010 Cab. :thumbsup:

Actually I don't like Dillon. I bought a load of reloading equipment at an estate sale for $50. I sold some of for more than $50, so in my book the tumbler was free. The media separator is a midway. :smile:

Whaaaat? :shocked:

You call that testing? That's average use for my grapple!

 

[WoodChuckDad]

At what size tractor would you recommend a heavier grapple?

 

[CCWKen]

Here it is if you haven't found it yet. https://youtu.be/_wle8iv4VhA

Thank you and Yikes! It says a lot about Kubota equipment too. Most others would have broken in half or pulled the FEL off. That grappler is a monster.

Do you have a tractor?

 

[EverythingAttachments]

At what size tractor would you recommend a heavier grapple?

The 73" Wicked Grapple in the video is extremely good for tractors up to around 75HP.
We also offer a 55" Model, which is just as strong.

We also have it's heavier sibling, but haven't priced or made a video for it yet. :thumbsup:
