restricting flow

[bigdeano]

Would it be possible to rig up a stop for the handle to limit the flow? Might be simpler then modifying the hydraulic parts. Just feathering the valve would probably work but might be difficult to control without a stop for the handle.

Hey, I made up my own.
Simply brazed closed a suitable fitting and then drilled out a small hole.
If the hole results in too slow an action just drill a bigger sized drill.

Did that as reducer was not stock locally but at that a reducer is a mere $5.00 item.

Go here, get 4 pieces of part number 1201192 .

Use 2 of them as is for the chute. Drill the other 2 out to .045 for the diverter-grapple. Install next to the male couplers on the hoses.

you rock- that's the kind of answer i was looking for

one of these days i need to order an TNT from you

thanks for being a great resource

Thanks to every body

Anyone have an idea why i can't seem to just feather those controls?

so if my desired flow is that much and rated flow is 8.6 or so, why can't i just feather the lever and get it to move slowly ?
are the 4th and 5th scv just not very proportional?

If your 4th and 5th scv are controlled with the joystick you should be able to feather the chute. If the 4th and 5th valves are solenoid operated valves these are usually either full on or off, no feathering to it.

I have proportional valves for my 4520 to install this winter but these are pricy and require the proper matched controls to make it all work.

For your needs slowing down the chute swing speed I would do what Brian recommends.

they aren't controlled by a joy stick they are controlled by 2 levers mounted onto the lower right side rops
seems like they ought to act proportionally but in practice it feels more on and off.

and i intend to follow his advice

thanks

All spools are not cut the same. Sounds like yours were cut to be either open or closed. While yes it is possible to feather, the movement has to be so very slight that it is impractical to expect to be able to feather the controls with much success.

Flow restrictors should take care of your concerns. :thumbsup:

Bumping the handle quickly in either direction is another approach. Might even consider adding an extension to the handle to give finer control.

What is gpm flow of the valve you have? You gpm might be way off to keep you from feathering.

don't know, i believe its the standard kit from deere -the dealer installed before i took delivery, i'll have to look and see if i can find any part#'s

I've tried the bumping thing, its the only way i can operate the chute and diverter, but the action is basically kind of violent the smallest bump rotates the chute probably 30-45 degrees

i fear Brian may be right on the type of valve
