4100 three point intermittent lift problem

acs55812 · Jan 18, 2011

Hmmm,,,,strained the fluid and put it back in, cleaned all metal filings off screen, rotated the rate-of-drop knob (it was frozen but freed up fine) and put it back where it started. Went out and plowed snow---verified that when the 3 point wouldn't lift the front still does lift.

The tractor was in a better mood---when I would back away from the snow pile with the rear blade it would lift, I never did get the impression this time that I would end up dragging it back to the shop for failure to lift completely like I had last time.

So if this knob that I thought was a rate of drop knob is actually a flow rate knob---yet the front lifts fine does it control the flow rate separately front and back?

I will send an email to my dealer and see what they suggest.

That knob only control how fast the 3PH lowers, it has nothing to do with the raising speed of the 3PH or anything else...it only decides how fast the fluid can escape the cylinder that operates the 3PH.

Kenny, I'm sure you are right about this. (I know better than to argue with you)

But I wonder if it is the same with the ''cut''. I may be wrong but seem to me that I have tried to lift my 3PH this summer and it wouldn't come up because the control was completely closed.

It is true do, that with the control set to lower the 3ph at a slow rate, it does not affect the speed of the raise. I'm on the road today, but will try it tomorrow

Please do

Got back this evening from my road trip and decide to check it out, and yes I was right.

With the knob completely close, the 3ph will not come up. But as I mentioned in my other post, you cannot adjust the speed of the lift, only the decent. As soon you turn the valve to open the flow the 3ph raises at full speed. Now this apply to the 2305 and possibly to all 2000 series, but I don't know if it is the same for the 3 and 4000 series.

Interesting, I do stand corrected. For sure my 4110 does NOT operate that way.
