I need a measurement please.

I'm having difficulty with the breakout force on the bucket on my Kubota L3540 with a LA724 loader with the QD bucket system.

Just got the tractor back from the dealer, they went through the whole hydraulic system and also turned the pressure to max specs.. the problem is still there.

The Kubota tech noticed the bucket I have is not a Kubota bucket but an old bucket made up by the previous owner to work on the QD system. It did not go with the tractor to the dealer, it had the grapple on it.

Anyway, he's thinking that the bucket is to long giving up its proper leverage, so what I'm needing is the distance from the hydraulic cylinder pin to the leading edge of the bucket for comparison to the one I have now. He did not have this model loader/bucket on his lot to measure nor could we find measured drawings showing this distance.. your help would be much apreciated.

This is a side picture of my current bucket, distance from that pin to leading edge of my bucket is right at 35 inches.

Thanks.

I have a LA724 loader. I would be glad to measure for you. I don't quite understand stand what you need measured. Is the bucket curled all the way back for the measurement?

24" on my LA 525 if this helps.

Thanks, probably just flat on the ground, thats the position I measured mine in.

Thanks, does yours have the quick detach bucket?

Yes I have a QA loader. I have a friend with a LA524 loader. The bucket on my LA724 is considerably bigger.

Any way, with the bucket flat on the ground, measure from the pin on the end of the curl piston to the front edge of the bucket..

Maybe even from the front edge of the bucket to the bottom slot on the QD mount

thanks

The tractor is at my grandpa's place now. We have been loading dirt with it. I will try to measure it today, but it might be a few days.

Ok, thanks. I just went out looking at this thing and thinking about whats happening. I think what I need is a measurement from the bottom pivot pin to the leading edge of the bucket. The tech was talking about the geometry being wrong, so that pivot point would make the most sense as to where to measure from, also.. that measurement would be the same regardless of what position the bucket was in.

Thanks again.

And it looks to me like we both like the same caliber!

27" on my LA724, for comparison.
It's a pin-on, so probably a little shorter than your distance would measure.
It's the HD "round-back" bucket with a bolt-on cutting edge.

Sorry for the long wait, I forgot about it. I had already taken the bucket off and put on the grapple before I remembered. The bucket is 21 inches from the cutting edge to the back of the bucket. It is probably 6 more inches from the back of the bucket to the pin.

Thanks, already bought a new bucket and it was worth every penny.. working well now..

What was the size difference?

What was the size difference?

About 9 inches or 30%.

The new bucket is right at 20 inches straight line from the leading edge to the flat where the loader attaches, the old one was 29"
