B2601 FEL Capabilities

[msmcknight]

Hi guys,

I'm still trying to understand what the capacity numbers on a LA434/B2601 loader mean...

If the breakout force is 1521 lbs at the pivot pin, does that mean it should be able to curl 1521 lbs?

If lift capacity is 948 lbs at the bucket pivot pin (max height), should I be able to pick up a pallet loaded with 948 lbs of material? What if I just want to lift the pallet off the ground about 6" ... should I be able to lift more than 948 lbs? Capacity goes down the higher the load is lifted, right? So if the limit is 948 lbs 7' in the air, what is the capacity at 6"?

What's the heaviest load any of you may have lifted with a B2601 and a set of forks? At what heights were you lifting?

Thank you,
-Michael

Pivot pin is where the bucket rotates or pivots. A lot manufacturers use pivot pin as a spec?

You don't typically use that as a lifting point. I tell every customer the real number is 500 MM forward spec. or 659 pounds

When I was having hooks welded on my bucket, I had one welded on backwards.

In that way, if I have to lift a load at the limit of my FEL, I run the chain over the top of the bucket and down between the FEL and front of the tractor securing it to the backwards hook.

Sometimes it gives me just that little extra lifting power as the lifting point is now very close to the bucket pivot pins.

I have the B2620 (basically the same as the newer B2601 capacity wise) and I unloaded a 534 pound crate (wood splitter) off my flat bed trailer with these bucket forks.

They take a lot off your capacity because they add so much leverage out front of the bucket, but it could lift and curl that 534 pounds effortlessly. I was pretty suprised and impressed.

That's the only thing I had an actual documented weight on. And I know it will lift more than that now.

Thanks guys. Can anyone explain what it means in the B2601 brochure when it says "...breakout force is 1521 lbs at the pivot pin..." -- and the number jumps to over 2000lbs at 19" out. It sounds like that would be a curl. I mean what else would be the "break-out?"

 

[ItBmine]

Yes, that is the curl power when you engage the bank.....the power it has to curl and break in to the pile.

These are all great questions, and exactly the thoughts that went through my head when reading the specs for the first time. How do I know what this thing can or can't lift?!?

A "rule of thumb" (and that's just what it is, a "generality") with Kubota loaders is that the number on the side of the loader, e.g. LA1353, LA525, etc multiplied by TWO is roughly your lifting capacity at the bucket pin. So an LA525 would be 1050 lbs, or an LA434 would be roughly 868 lbs at the pin. Again just a generality as there is some variance, but this gets you real close.

....And...the lifting capacity is based on a certain hydraulic pressure, and may (will) change depending on whether the rear of the tractor is counterweighted by, say, a finish mower or bush hog, weight box, etc. I know that an L2501 won't pick up 1050 lbs (LA525) without lifting the rear tires without a counterweight of some sorts. And fluid filled tires only help marginally; need the weight BEHIND the tires.

Great point, lugbolt.

I have a friend with a Mahindra.

His selling point was the FEL lifting capacity nearly doubled a similar Kubota. Think it's an equivalent to a Kubota B, with almost a 2,000 lb lift capacity.

I said good luck....you'll never see it......except on your nose, if your front axle can handle it for long!!

This just blew my mind! I love tools like this!

Is there any rough rule of thumb to calculate lift capacity as you move further from the pins, like subtract X amount of pounds for every inch away from the pins?

Thanks for sharing.

No. Your answer depends on your geometry.

I was literally just looking at this as I am moving to a larger farm and may need to move round bales

 

[anavidi]

No. Your answer depends on your geometry.

I should have specified that I only would want that rule of thumb for my specific loader not all kubota loaders.

I just learned that the number on the side of the FEL is the lift capacity at the bucket pins in kilograms! And there’s about 2.2 lbs in 1kg hence the rule of thumb!

I have a question. The other day I used my friends L3400 tractor with a la465 loader and a heavy duty clamshell bucket to load sand into my dumptruck.
My B2650 has a La534 loader with a 54" bucket. The L3400 is differently a bigger tractor and the loader and bucket look bigger than mine. It lifted full scoops with no problem. It took a minute to get used to it but was fun to drive a bigger machine! Question is: Why the smaller Number on the L3400 loader. I am guessing it is 6 or 7 years old at least.

Thanks in advance for your responce(s)! I really appreciate all the knowledge on this site!
