Third function dirverter valve vers True 3rd function valve

[k0ua]

One of your rear remotes can be used as a "third function" by running the hoses from the back to the front. With this setup you would have one hand on the loader joystick and then use your other hand to control the third function. Personally this would drive me nuts! But several on here not only do this, but like it.

Not in every case.. Some of our joystick and rear valve controls are close enough to operate then all with one hand. Using my fingers on the rear remote valve and my palm on the joystick. It doesn't seem to slow me down a bit. I would not like it if you had to move your hand off of the joystick to actuate a valve by your side but by not having to move your hand, I like it a lot.

The function diverted will be locked in place just as if the valve was shut i.e. not being used.

Question - will the loader arms and curl still hold when the diverter is operated? Example loader at full height and grapple set to place bails on hay stack. If the diverter is on the lift circuit, will the loader arms drop when flow is diverted to release the hooks?

No, they will not drop, remember there is fluid on both sides of the lift cylinder(s), There is no path to exhaust the fluid out of the cylinder because the diverter valve switches both ports. There is no place for the fluid to go, so the cylinder cannot move.

Thanks everyone - I am learning a lot.

I have a simple question.

If you have a thumb and you close it and curl the bucket on a backhoe does the curl have to overcome the pressure of the thumb? To push it back onto the cylinder?

If not how does the thumb hold the load in place? How is a thumb setup? Is there a maximum pressure for the thumb in relation to the bucket?

 

[LD1]

No. If installing a thumb, it should be designed to give similar power/force at the tip of the teeth as the bucket. That way neither one can "overcome" the other.

If you have a thumb with too small of a cylinder, when clamping down on something by using the bucket, you can blow hoses off your thumb cylinder or damage the cylinder.

If the power/force between the thumb and grapple are roughly the same, you have a stale mate between the hydraulic forces, and maximum clamping ability.

I'm still getting use to my grapple diverter set up. Don't think I am coordinated enough to do more than one thing at a time with the lift curl clamp process. I did bend the tips of the top clamp moving that darn cultimulcher the other day. Mild steel. My son was able to hammer the tips back straight. Got to weld a gusset all the way to the tip. The current gusset goes to within about 4 inches to the tip end. Other than that works great. Best $$$ I've spent in a long time.

What brand/model grapple are you using? Most that I have seen have the tips gusseted all the way especially on the clamp.

This is it LD. You can see from the pic that the gusset goes down to within about 4 inches of the tip. That is the only issue I have had so far. I looked real hard at the other manufacturers but I was able to score this one under list price at Kaufman Trailers. They are the distributor for American.

Yep, certainly a weak area on that one. I'd gusset it for sure.

I have had ~12" diameter logs that were about 20-30' ling between them teeth before and pulling them backwards. When turning it puts a heck of a stress on the teeth. If mine were like yours I'd have bent them multiple times by now.
