question about loader capacity vs tractor (long)

KiotiJohn · Jun 7, 2006

When I try to pick up a too-heavy load, my relief valves kick in and I can't go any higher. I would have expected that yours would also do that, but clearly it's allowing you to get up pretty high, and then damaging the rods. Something is not quite right about that.

That said, if you have plenty of those monsters, and you keep lifting them that high, you're going to eventually be in trouble, or run out of time because you're always having to replace the cylinders.

You have that heavy grapple on the tractor which already weighs a great deal. I'm not sure just how much extra you "should" be lifting, but damage shouldn't be happening.

Rent an excavator for the main large stumps and get them gone. Use the JD for the lighter stuff that won't damage your cylinders.

I will admit to having a problem with using any equipment I own to it's full potential. The way I can get the stumps up as high as I do is that I have figured out if you curl them under the loader arms the load is effectively reduced allowing me to pick up the stump higher. Then I can curl the stump to above the arms. Then things break /forums/images/graemlins/frown.gif

There is no relief valve in the loader circuit when I am not using the lift function. I figured this out early on when I was trying to skid a large rock (that I couldn't lift no matter what I did & backed up onto a small mound. After I passed over the mound the rock was off the ground 2 ft (I had raised the loader because the rock was digging into the mound).

( Otherwise, have you thought about skidding them from the 3pt? )

I had drawn the conclusion from the board that skidding anything from the 3 pt was bad without using a "skidder type" thingy attachment /forums/images/graemlins/confused.gif

( I would vote for a larger tractor. )

But my question is..

A larger 4wd clone of what I have? 580, 310 etc?

or

An excavator & smaller 4wd "farm type" (IE no backhoe)

I tend to run equipment up to & sometimes past it's limits as well.

I'm a bad one to give advise as I'd say get one of each /forums/images/graemlins/grin.gif

How about a large tracked skid loader?

We have had a 2wd 14' class Allis-Chalmers TLB (equal to a Case 580) for decades and it's structure is far more rigid than the ag tractor loader.

An excavator with a thumb would be handy but not had an opportunity to operate one.

I generally make do with the TLB and a dozer to clear/develop lakefront lots.

How about just adding a bypass valve to your loader's bucket curl circuit and living with its limitations. The bypass valve would prevent accidental damage, but then again, it sounds like you're finding ways to "bypass the bypass" valve that's already there... /forums/images/graemlins/confused.gif

I'm with the rest of the posters. The industrial tractors (like a 580 or a JD 410 or something even bigger) are made for this kind of work, and if they won't lift something, it probably won't break 'em. Quickest way to deal with all those stumps though is with a tracked excavator with a thumb and a good operator. Probably cheaper than a new tractor if your 110 is the size unit you want once you're finished with the stumping. It's a cute devil - hate to see you wreck it!

wow!
that's quite a statement for the power of that
110, and obviously it's being pushed past it's
limits..
keep in mind this machine is based on a
43hp compact tractor, NOT a full size
TLB.
I think an Excavator or big backhoe is the answer..
but, ****, what an impressive sight.
The grapple sure puts the load out in front
of the loader boom.... which is what others
are saying is the problem.

good luck with the rest of the property!

I think you know the answer to your stump removal problems is a more capable machine. I move huge rocks I can hardly lift with my rock bucket, but most of the time, I'm only 4"-6" off the ground and sometimes even slightly drag the ground. I have to touch-up the curl and lift with the joystick every few seconds and that provides some relief. My cylinders are also in hydraulic lock without the joystick SCV in operation. I just think your lift cylinders are very vulnerable when they are 2/3 extended. To see what pressures are being developed, you could "T" in a 10,000 psi pressure gage with quick connects and watch it when you are doing heavy lifts. My guess is that the hydraulic pressures will be doubled or tripled under dynamic shock loads. That would provide you with a definitive answer instead of our speculation. /forums/images/graemlins/cool.gif
