3pt. bogs & chatters on Ford 1510

[geezer32095]

Thanks to all.. All's well that ends well Checked the system out with the gauge and it's operating within the limits. The bogging was happening when my friend raised the operating lever above the point when the lift arms hit the top. Relief valve is holding @ 1800 psi. The max for the pump is 2,133, so all is well within limits and the scoop comes up with a full load even at low engine rpms. No need for adjustments but it was an education for me.

Your feed back is out of adjustment. Check your manual and see if you can find it in there. If not repost and someone can walk you thru the adjustment.

I 2nd what Leejohn stated that feedback linkage(parts keys #27,28 & 29) needs adjustment. On tractors I've been around if feed back is "adjusted correctly" 3 pt won't raise far enough to cause valve to go into relief.

OK Tx Jim I didn't understand what L.J. was saying. Not familiar with all these little parts nor their adjustments. I will look at it tomorrow but I doubt I will kno if it is correct or not. I don't think linkage can go any higher or it would hit the bottom of the seat, it is very close now as I recall. Partly because I redesigned the location to be as far back as possible to get my knees out from under my chin. (and I am not that tall only 5ft 9in 180.) So you & L.J. are saying I don't want the relief to activate. The system should operate at 2,133? & it is raising too high now??

The one other thing I don't like about the tractor is that I can't easily get my size 10 boot between the fender & gear shift. I am thinking of removing some of the fender's leading bottom edge.

If I move the linkage to a position hole (there are 3) closer to the tractor it should lift a bit higher?? Will I lose some leverage that way??

I'm not familiar with the feedback rod on your Ford but I am familiar with the feedback rod on my Kubota M7040. The FB rod on my Kubota required adjustment so as 3 pt hitch would raise to it's upper limit. One just sets turnbuckle on FB rod where relief valve is seated(not by-passing) when 3 pt is at upper limit and 3 pt control lever is at rear of the slot.

So the feed back is connected to a relief valve??? Hmmm it appears there is also one in the diverter/manafold block where the FEL would be hooked in if there was one. Is it likely there are 2?? I can't see one in the blown up view you posted.. Or what the FB rod is attached to either. I am not at all used to looking at these sort of views..

How does one know if the links are raising to their max? I think they are, they go up and stop with a definate "thump" before the raise/lower lever reaches its furthermost position possible in the bracket. At that time the engine starts to lug so I moved the upper limit stop to that point. Then it doesn't lug any more..

I found the feed back rod but I still don't understand its function or what to expect if I lengthen/shorten it etc.

I was told the relief valve will give a high pitch squeel when it goes off. I am not hearing that. When I had the pressure gauge hooked in, the pressure on start up did go to about 1800psi then drop 100psi
I can't be sure that the used pump is producing 2133psi either..

On my kubota I moved 3 pt control lever rearward then with no implement on 3 pt lifted up on one 3 pt draft arm. It still had some rockshaft rotation so I adjusted feedback rod to just where I could hear relief valve then back feedback turnbuckle off 1/4 turn. 3pt raised to it's limit with no relief valve noise. Yes it would have been more scientific to install a hyd gauge on rockshaft control valve but my tractor has a cab in the way
