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.

I was referring to the vibratory case cleaner and case media separation device

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.
