3 point lift?

Caryc · Apr 6, 2015

What is the maximum one can expect the three point lift to lift on an 8N? I'm thinking about buying the carry all at TSC. It's rated for 1000 pounds. So it doesn't look too bad for $129.

I wouldn't try to over load it's rated limit. But there are other carryalls rated at 2000 pounds. So, what will the old girl pick up?

I have an FEL so there is plenty of weight on the front of the tractor.

Roughly 800 pounds.

With out the loader up front the 3 point can lift 800lbs with out the front tires coming up. Add a loader and you can probably lift close to 1000lbs before the relief valve starts to say to much for me

So the relief valve will keep you from overloading and screwing up the pump? What happens? I mean it just won't lift?

I bought one of those last year. I haven't tried lifting anything near its rated limit but it's well constructed and should hold up. Can't beat the price.

ook at those lower lift links. The top cover lift arms are connected to those lift links by the leveling box & a lift rod on the other side at a little less than their mid-point. Think crowbar/fulcrum/mechanical advantage/disadvantage. With all that in mind, then I tell you that if I slip a ten foot pipe over one lift link then the lift can't lift a grown man sitting on the end of that pipe, but it can lift 1,000 pounds when placed directly over the end balls of the lift links. So, what it can lift, depends on how far it is hanging off the rear.

The geometry of the thing is not at all hard to understand. It's mostly common sense. I guess what I should have asked is what can the tractor safely lift without damaging the hydraulics in some way? I'm not concerned with bending lift arms, what I'm concerned about is the pump.

(quoted from post at 19:12:12 04/06/15) Pops off like a relief valve on a compressor--whatever u are lifting hits the ground..then
it will reset itself and you are good to go--UNLESS u overload it again..

I don't quite get your "UNLESS u overload it again" thing. Doesn't the relief valve just reset itself so it's good to go again?

What does your "UNLESS u overload it again" thing mean? Do you mean "again" by two minutes later, five minutes later, five days later? You lost me with that.

t is just a spring loaded ball & seat. Enough pressure compresses spring & as pressure falls below what it took to compress spring, it re-seats. See if I have a picture for you.

Virtually exactly like this Fregy:

Thanks JMOR but I still don't get the "UNLESS u do it again" thing.

t automatically resets & will relieve again the next time you overload it. And again the 3rd, & 4th & etc., forever.

In theory I would think that if you over load the 3 pt you would not get it to raise at all. The safety valve would pop open once the hydraulic fluid was redirected to the 3 pt and the safety valve reached its safety rating and opened. Remove some weight to get it below its rating and the arms should lift.

Now if the arms were up and you began adding weight, the arms would drop once the valve reached its rating again and would not lift until weight was removed.

Tom N MS · Apr 7, 2015

Simply meant you are good to go--but if u overload it, it will do the same thing again-which is what it is suppose to do..Now, who can't understand that?

The object of a relief valve in anything is self explanatory. To relieve excess pressure. Doesn't take a genius to figure that out.

But your use of those caps "UNLESS" gives one the impression that something drastic will happen. Sort of gives one the impression that you're saying don't dare do that again.

Oh, and JMOR, thanks for indicating that I'm an idiot.

Hey Cary.......I have said carrier on the N....and one on the 861.....well....off and on the 861...... 800 pound round bales....no problem....loaded

How is it packed? I mean does it bolt together? Or are the two arms welded to the two upright pieces? I'm just wondering, will it fit in my Ford Aerostar van?

mbramble · Apr 7, 2015

It is welded.....

Could you or one of the other guys here please give me the measurement of the upright pieces and the length of the forks? They don't give the measurements on TSC's site.

Trying to figure if I can get this thing into my van.

mbramble · Apr 7, 2015

uprights 36"
forks 36"
width 32"

Ed Douglas · Apr 7, 2015

Cary.....I think what you're asking.....is CAN you damage the pump......no.....the pressure relief would preclude that!.....having said that....800
pound bales are a walk in the park....for my N....I suspect I could lift more....the other issue is the age and condition of the pump...and
cylinder......original with wear???...rebuilt 5 years ago??.....these are a couple of caveats......you see where I am going.....how much are you
looking to lift?....I am curious now??.....perhaps starting there would help you decide my friend.

Thanks Ed,

I really don't have anything very heavy to move. I now have a lot of cut up three or four inch logs from tree trimmings. I probably wouldn't have anything close to 800 pounds anyway.

My hydraulics are in good condition. I just thought it would be good to know the limits.

I built a tray for mine, sounds like you could use one too.

ScoutB, Very cool looking thing you built there. Looks pretty simple to build also.

It's pretty handy for sure. It built it hinged and held with 2 bolts and a pin so it stores flat.

All very true. But let's say I tried to pick up 1,000 pounds with my 8' boom pole. The load obviously stays on the ground but is there enough torque to lift the front wheels off the ground?

Ed Douglas · Apr 7, 2015

Well there ya go......you're golden!......always good to have an Idea about the limits......and sensible to take precaution not to over tax the
hydraulics.....

es & no. Depends on condition of your hydraulic system. Perfect hydraulics & non-weighted tractor = yes. Old & worn & leaky cyl &/or pump = no. I have done these things with tractors in various conditions. Some will 'almost' lift front end, such that my arm will go ahead & put it over the edge & front end lifts off. Also, it is probably worth pointing out that the 3 point lift capability is quite nonlinear. It will lift more/less at various points in its travel than at others. This it due to angles involved in the many pieces of linkage between the ram piston & the lower arm balls.
