Loader LS Loader Performance

[I have no memory]

Short Game,

I think you've done a great job finding the design issues and using practical examples to explain it. Some people on here drink blue cool aide and slam anyone who has any issue with LS constructive or otherwise. I appreciate your analysis and it makes complete sense to me. You might want to ask your dealer if LS will upgrade your cylinders for free since your disappointed with their performance. Larger diameter cylinders will give you more force with the same pressure.

Agreed, you've "done the math" on this and I don't see how anyone can take issue with the fact that you reasonably expected the LS loader to out-perform the one on the Cub Cadet.

Just another 2 centavos...

Thanks, friends.

I would always welcome well thought out and validated complaints. If there is an issue or weakness on one particular tractor or model then there is. It doesn't mean Short Game or anyone else is disloyal. It just means they are working out an issue. I mean read the Kubota forums or the John Deere forums...they have issues too. I also think people jump to conclusions on the other side with the blue kool-aid and choir boy stuff.

That being said it seems like you have played detective and figured out the culprit is the cylinders. Now you just need to figure out how to test that theory and if it is correct you need to get the cylinders replaced.
On my 2011 I am immensely impressed with the loader capability so this also lends to your theory. I am lifting 8 foot big ol logs that pull the back end off the ground (filled tires and box blade attached). I scoop up full buckets of rip rap 6-10" stone and it doesn't blink. I think it would really make you happy to get this resolved so you have the FEL power of which the tractor is capable.

When I got my LS, it seemed the loader was lacking some power so I adjusted the pressure relief a couple of turns. I didnt have a gauge, so I didnt tighten it much but it did make a difference. I finally got around to using my brother in laws Boomer 2030 and the hydraulics on his FEL are very weak. It wont pick up the tractor with curl either. I had been wondering when he would learn to get a full bucket of dirt and now I know why. His seems really week. I am going to try to find a pressure gauge that we can rig up on our tractors and check all of them. My LS dealer said that he has not been checking them prior to sell but said he would from now on. I think NH dealers should also. Hopefully they havent set the pressures so low because of a low strength issue with them.

I bought my U5030C new in May. Does it have the new and improved cylinders? How can I tell? Thanks.

I think you have an all around bigger loader on that model.

You have a LL5102 loader on the U5030

Here are a few pics of the 4101 loader installing a pole with our R4041H

Short Game is probably right in his assessment of the pressure, and the location of the tilt pins/tabs

If the loader was designed this way, then as Short Game said, that is unsatisfactory for his use.

The loader specs should have been stated, as most loaders have specs showing the lift force and the breakout force.

You can fool around with the relief setting if you know the pumps limit on psi.

Another option is to obtain a different loader bucket that better matches the desired capability, or build one to suit .

Larger cyl will help a whole lot . see below.

The mounting pins and distance from the cyl wall has to be just right. May be a problem.

Using 2500 psi, a 2 in cyl 1 in shaft, will develop a force of 7,864 lbs

-------------------3 in cyl, 1.5 in shaft, will develop a force of 17,671 lbs
