Can my John Deere 2155 lift/move 1 ton armor stone?

[Black Acreage]

Hope to build a retaining wall without having to rent another machine. Obviously it would be easier/safer with a fancy excavator with thumb/sling/etc. attachments (or maybe even just a skid steer with forks) but I just need to know if this can be done.

Can my '89 JD2155 handle it?

Looking at Tractordata I see lift capacities ranging from 1657lbs "full at pin" to 4350lbs "breakout" depending whether a 520 or 540 loader. I don't know which one I have and I don't know what these terms mean. Time is of the essence so I'm just hoping for a more or less bottom line answer before I order a pallet of these things

Thanks in advance to those in the know!

If the numbers you are quoting are correct, then no you can't lift it.
I assume that you are concerned about taking it off a truck when they deliver it? That would be an issue!
. However, if you are just wanting to know if your tractor can move it around if you go after it in your truck and are able to move it, then you are looking at the wrong end of things. A 3-point set of forks is a lot stronger than a FEL, so keep that in mind.

1657 Full at pin means 1657 pounds at the pin that is basically the back of where a pallet would set up against the forks. As weight goes forward from there, it is harder for FEL to lift it. (Weight at tips of forks is harder to pickup than if it is slid up against the rear of forks)
The Breakout force is the weight the bucket curl will pick up, so basically what you can pick up with it against the rear of forks just enough to clear the ground when you roll the bucket backwards (or up-ish)

Lets look at all of this.

You have a tractor that weighs 5900 pounds. You add a loader for an additional maybe 1000 pounds. To this you add a 2000 pound load in the bucket. You are now looking at a total weight of 8900 pounds. Lets add you in the seat and call it a total weight of 9000 pounds.

Next you realize that when you lift the load the rear end comes off the ground. Unsafe but when the rear wheels are off the ground you are now loading all the weight on the front tires. 4,500 pounds per front tire.

To counteract the lifting of the rear wheels you add 1000 pounds of counterbalance on the three point. Counter balance works, you now have 500 pounds of down force on the rear wheels but have added the other 500 pounds to the front axle.

Final question is, can every component in the load path to ground safely handle that weight? Sadly, these situations frequently are why we have tractor operator fatalities.

Just my 2 cents.....

I think your weight transfer calculations are a little oversimplified but I get the point you are trying to make. I'm pretty sure there is a video out there where someone has done tests with scales to determine how much adding counterweight unloads the front tires. think of your example. if you add enough weight to the back the front axle will lift off the ground. plenty of videos to support that theory. Mostly from developing countries.

ratings for loaders (depends on the manufacturer) are usually to full height so your loader could lift 1657 to full height at the pins, capacity at ground level would be significantly higher, its not double but it is more than just a hundred pounds. My loader owners manual has a graph that shows lift capacity VS height.

my 854 loader can lift roughly 2489lbs at the pins to full height but can lift close to 4070Lbs at ground level.

are you talking metric ton = 2200lbs or 1000 lbs.

technically you could use the break out force to lift 4350 lbs a couple inches off the ground but that is probably not safe especially if your working on hills.

Clamp on forks.....probably not.

Bucket off and either QA or pin-on forks.....I'd say it has a pretty good chance of lifting and moving.

Loaders lift way more at a lower height due to the geometry and angle change of the cylinders.

Make sure you have something heavy on the back. But the 2155 is a pretty stout little utility tractor

Incorrect about breakout.

Breakout force is how much the loader will lift at ground level. Curl/rollback force is something different

Some loaders list capacities at ground level (breakout).....capacity at 1.5m (59") and at max height.

I'll post this anecdote, re- just because you can lift something near the capacity of your tractor doesn't mean that you should.

Neighbor asked me to move a full pallet of cement blocks to the other end of his yard. Forks on loader, medium heavy box blade for ballast. Tractor wouldn't lift it so we removed some blocks until it would. So we were within maybe 100 lbs of actual* lift capacity. Even though the yard was flat and smooth(for a yard), that trip across the yard was SQUIRRELLY. Wouldn't want to do it repeatedly, or across a pasture, or on the slightest slope.

*I don't know but rated lift capacity might be lower than actual lift capacity for stability reasons.

Can you get an extra pallet and split the load?

I assume the 4wd version has the HD loader, which has half a chance of lifting a ton rock. If you are doing dozens of these and 8' high I think a good size excavator would be a good idea. Or if you have a sloped working area. I think it would be hard to eye ball a 3000lb rock vs a 2000lb one as well.

A dozen rocks and only 2 layers tall?, sure give the tractor a try, keep the load low and go slow, with a ton of something on 3pt. Leaving the tractor in 2wd also lets you know if one side getting light, and be ready to drop the loader arms if you feel a bit tippy.
