Loader Lift Capacity vs Curl Capacity

[Reb954]

So what we have learned from all of this is simple, the angle to the dangle matters so pay attention to it.

At the end of the day, if your tractor won't pickup the load, figure out a way around it.

Easiest solution is to just look up the specifications.

All of this cylinder area discussion is mostly useless. The leverage disadvantage of the curl cylinders is less than the lift cylinders which would offset all or most of the reduction in strength. The lift cylinders are probably working at least 4-1 leverage loss. The curl cylinders are probably like 2-1 loss.

Where I see the curl function seeming weak is when digging into a pile of dirt or gravel. The pile is often deeper over the front edge of the bucket and I can’t curl or lift the bucket until I back up a little. I only have experience with a Kubota and a John Deere but all the end loader features seemed sized well for the tractor. The bucket size wasn’t to big or small, the curl, dump, lift and lower functions seemed the correct size.

I never considered the backward acting bucket cylinder as being an advantage in that respect. I just know, everything seems set to very conservative values. Not like you could ever stall the engine. That would be nice. To get all the digging power possible.

And notice how they are able to achieve better cylinder/link geometry too...it's not on accident.

I've had people complain that they can pick the rear of the tractor up with a heavy load in the bucket.
I've had people complain that their loader is too weak to pick the rear up with a heavy load in the bucket.
I've had people complain their loader can curl more than it will lift.
I've had people complain their loader can lift more than it will curl.
I've had people complain their loader wouldn't lift the front wheels off the ground then lie about having the brake locked when they were trying.
There is a single factor that limits every operation. Sometimes that limiting factor is in the seat.

I guess they achieve self levelling the same way. Compare that to the horrible clunky, and rattling system on our 6200.



Interestingly, both machines as different as they are and the JD having 75% (or so) more HP, have similar lifting and breakout capability.

Our little PT425 has a rollover assembly that reverses the path of the curl function. It pushes to curl and pulls to dump.

And the simplest mechanical self leveling known to man.
