Hydraulic Flow Reducer - do they exist?

[OtterBrookStables]

I have a 72" Frontier Snowblower on the back of my 4120. The chute rotation is hydraulic. Problem is, when you move the lever to adjust, the chute moves VERY quickly - it basically slams to the other direction. You have to carefully feather the hydraulic lever to get any slow adjustment of the chute rotation. Do they make a hydraulic flow reducer (or something else?) that would slow down the chute movement? It would be ideal if there was an in-line quick-connect unit that would go between one of the chute hydrailic lines and the quick connect on the back of the tractor. Ideas?

a couple of years ago the chute rotator on the front of my 2210 stopped working so I took the fitting off at the hyd cylinder and there was what looked to be a simple flat washer with about a 1/8th hole drilled in it I believe for that same reason. There was a little shmegma blocking the hole so I cleaned it and all was good again.

You should be able to put a reducer or valve in there.

On my former 3720, on the front A-Frame lift it had a nice valve that allowed you to
adjust the lift/drop speed by opening or closing the valve. I thought it was funny that they never put such an adjustment on the chute. The Chute on my 4720 (Rear blower) my former 3720, and my 2305 all go way too fast for my taste.

You need one of these in either the supply or return line https://www.surpluscenter.com/item.asp?UID=2348022514101309&item=9-4313-A&catname=

Blueone.... what you put a link to will NOT work.. Well, lemme rephrase..it will work, but only in one direction...what is needed is a Needle Valve:

A Needle valve meters flow in BOTH directions...

Correct. The proper search term (in the hydraulics forum) is "restrictor". The needle valves are best because of the adjustability-but they cost more. A small washer in a fitting drilled with a small hole works also.

Both of you guys are sort of correct.
The proper way is to use flow controls on each port of the cylinder and and control the flow out of the cylinder "free flow in - meter out".

If you use a needle valve the cylinder will operate at different speeds when retracting or extending.

Why do you think that?:confused2:

Heh heh heh ......... he said shmegma ! :licking::laughing:
