How much does that log weigh?

[LD1]

The ONLY thing I'm doubting is, "ANY" tractor/loader rated to pick up less than 3,000 pounds, picking up and walking away with 3500 plus pounds!

It's just NOT going to happen!

I know there have been several threads on this very topic. But you have to take the "rating" with a grain of salt, as the "rating" is max height. Loaders are WAY stronger at ground level.

Kubota actually publishes a force/lift height curve that illustrates this very well.

My loader is rated for 390kg (860lbs) to max height at the cutting edge. And 500kg (1100lbs) at the pins to max height.

In reality, at ground level, its rated for about 800kg (1760lbs) at the bucket edge and 1200kg (2650lbs) at the pins. But these are not published specs, and only shown in the manual.

So yes, MY loader "rated" at 860lbs at the cutting edge, can lift double that down low. And thats with no assist from curl, Which at the bucket edge is even stronger.

How far off the ground is the tractor in question holding that log??? Ground level??

At 18" off the ground, I am still at ~1000kg(2200lbs) at the pins and ~750kg (1650) at the bucket edge.

But its a moot point. Loaders are alot stronger than their "rating" suggests.

And the fact that the log calculator that calculated that log to weigh 4800# is just plain wrong.

His loader is rated at 2761# at the pins to max height, and 3700# breakout force.

Do I believe his loader will lift a 4800# log......probably not. But the fact that the log is probably around 3500#.....that I absolutely believe he can lift.

My loader is rated for 3650 full height, it will NOT lift a 3500 log/pallet forks/grapple to full height and I would NOT lift a 3500 pound log and drive around with it... My neighbor has a CIH JX 95 and my loader will pick anything his will, and it's no wimpy loader on his either...

NOW, you expect me to believe that little 35hp tractor will out lift my tractor or my neighbors JX95??

You have been drinking too much CUT koolaide! lol

If your loader is rated for 3650 to full height, I would be seriously disappointed if I couldnt lift 3500# at ground level.

I lifted 1500# I-beams off my 40" high trailer deck with my loader. Would only lift ~1" off the deck, and then I needed to use curl. And this was with CLAMP ON pallet forks.

I have also lifted logs that were in the 2500# range. No I didnt drive around with them, but just enough to get them off the ground for cutting up.

His loader is rated for nearly 3x's what mine is, So yes, I believe it can lift a 3500# log with the attachment he has. I know there is no way to confirm the measurements, but heck, there is a picture of the thing. And its an impressive lift for a small tractor.

Certainly not drinking any koolaide. But look at specs across various MFG's. It seems most of the good 40-50HP tractors have 2500-3000# loaders. Just about double what a 20-30HP tractor is rated for. But jump to your size class, 90-100HP, and the loader numbers certainly dont double again. It seems they kinda fall off. IE: 30HP - 1200# loader, 50HP - 3000# loader , 70hp- (maybe 3500# loader) 90-100HP...maybe a 4000# loader.....120+hp....maybe 4500# loader. Just the way it is.

Read my post again, I said 3500 log, "pallet forks and grapple"... Do you think the log is the only weigh up there...

Now we are talking 4K +, it isn't going to happen...

Tractors are not made for lifting. A 90 hp tractor doesn't have the front axel to lift 6000 pounds. If you want to lift heavy loads get forklift, tehelandler, or wheel loader. Also the loader in discussion is rated to lift 2600 pounds NOT 3,600 pounds. Tractors put the loader on the wrong end for serious lifting.

With a loader, the lift capacities are rated with the standard weight bucket.

Sure, if your attachment is heavier or shifts the load further forward, that diminishes the capacity. But just because you dont "think" your loader will lift a 3500# log, doesnt mean another tractor configured differently cannot.

The fact that your loader is rated for 3650# at max height, means it can probably lift 5000+ down low. Again, I would be disappointed if I had a 95hp tractor and couldnt lift a 3500# log on forks or in a grapple.

The loader in question is rated @ 2761# TO MAX HEIGHT. That is what is missing here.

the Breakout rating is what is listed at 3700#, which is a much closer indication as to what it can actually lift near the ground.

How many threads have we seen over the years on here where a loader is rated for xxxx lbs and we see pictures and claims of lifting 1.5x's to 2x's what its rated for. The key is the lift height. The angle the cylinders are on is such that the lifting force diminishes the higher it is lifted. So the rating to the max high is the LOWEST rating for the loader.

Look at deere, they list a lift spec to max height, and a lift spec to a height of 59". the spec to the height of 59" is always significantly more. Its just that other MFG's dont list that spec to a lesser height. But that dont mean the loader isnt rated to do it

I'd love to stay and spar with you, but I'm off to go trade my tractor off for a 35hp compact so I can lift 3500 logs!! No sense in burning all the extra fuel I burn to get the SAME job done!! NOW I get it, i've been buying too big of tractors, all these years! lol

oooohhh, I better stop and buy some CUT Kool-aid too, or I'm thinking it won't happen...
