New L5740HSTC3 loader question

[daugen]

Still having problem with the curl. Now it seems even weaker, particularly when I try to pick up something at the end of the teeth. The bucket of firewood pic curled slowly, but did curl, likely because the weight was "in close". Almost feels like one cylinder isn't working. The tractor is going into the shop next week and I'll get the pressure checked, as suggested. Several people have told me the curl should be the most powerful part, but it sure isn't on my tractor. I can pick things straight up, say grabbing it with the grapple, but it won't curl, even when cranked out to 2500 rpm. Lot of storm damage cleaned up, and I've made myself a nice pile to work on the next month. Our township doesn't allow burn piles, which sucks, so I guess I have to push the unwanted mess somewhere where it will be seen the least. I grew up with burn piles but now apparently the smell of leaves and wood burning is considered "noxious" or whatever.

Boy did I do a number on my trailer. The front wheels of the Kubota are hidden by the loader, and several times I nudged the tail lights. Doesn't take much to make lots of little pretty red plastic on the ground...might see if I can get a light with a frame around it. No sense putting nice LED replacements in if I just crunch them again as I clearly have a ways to go on the learning curve. Just a little further....crack.

Have one more hundred foot tree to work on, but it fell into the field, and not on the road, as the others did, so I'm going to take my time with it. The barn has a large wood room and looks like I'll have it filled by the time I'm done. There's something about looking at those big piles of wood that is very satisfying.

Your tractor may be going into "relief",because its new to you,you are probably not familiar with the sound.Try lowering your three point hitch a little(from full up).I have the same loader and they are very powerfull.My loader(and third function) doesn't act right if the three point is all the way up.I believe there are adjustments that can be made but haven't been back to the dealer for service.Mine is due in the spring for service and will be addressed then.

interesting idea, but my hitch has a full ballast box attached to it, which currently is set about 8 inches off the ground. Not going any lower...
The lift is fine, it's the curl that's weak.
thanks

If your 3PH is not in the fully raised position as nybirdman pointed out, you don't need to lower it any further. Some have reported that in the fully raised position if it's not adjusted properly it will be robbing some flow from the FEL controls.

Pick up the 3PH then turn the knob under the seat to lock it then push the 3PH lever to the down position. I don't know if it will help but it is worth a try.

 

[daugen]

I'll try it, thanks.
When I press the FEL control to the left to curl up, nothing happens. No noise, no hiss, just nothing, with a heavy load. But vertical lifts are plenty powerful which is what confuses me.

I have never had any complaints about the loader strength on mine. I can pull in to a pile of dirt on curl a big bucket. Shouldn't the curl be stronger than the lifting?

 

[kuboman]

Sounds like the loader valve is out of adjustment or your quick couplers may not be full engaged for the curl cylinders. Try disconnecting them and reconnect after all the pressure is relieved.

 

[daugen]

great idea, maybe something simple. To get all the pressure out, drop the bucket, turn off the tractor, and then push the lever in all four directions, right? (I have a whopping 19.2 hours of FEL experience...)
Will try that tomorrow. I'm picking up heavy wood rounds and with a couple in the bucket, the curl either goes super slow or not at all.

dealer said hydraulic pressure was increased but still not to spec. But he was missing a particular test device and could not complete what he wanted to, but he will, a good guy. Seems to work a little better, but pushing into a gravel pile, I still could not curl at all today. I think this gets back to the problems with an 850 pound bucket/grapple way out on the end of a quick connect one ton capacity FEL. Two sets of wheel weights added which could be felt, but not a huge improvement. And I added the hydraulic top link for convenience, will consider the "tilt" function. Nice to get my tractor back and with nice weather ahead, I expect to keep it busy.

daugen,

Any news on the fix?

 

[daugen]

No. I got the tractor back with some improvement, but not much. The dealer was a little embarrassed to admit that they could not find the right test gauge..., but would get another one and do so. Their first impressions were that overall pressure was low but I think they are guessing without the right test equipment. They did add the wheel weights, which helped, but only a little. As has been discussed over and over, this bucket is just too big, almost half the capacity of the FEL but that in itself does not explain low curl capability. I used the tractor for hours yesterday moving lighter brush and it worked great, just not with heavy logs or gravel. The dealer did apologize for spec'ing the bucket too large for me and I think will try to get his next M customer to consider a nice lightly used grapple, and get me the lighter weight 66 as I should have had all along. The dealer is a friend and has provided me with outstanding service otherwise, so I'm treading lightly here.

I will follow up with the dealer regarding his pressure tester and I know they will make sure the tractor meets specs. They aren't trying to run away or around the problem, so I'm giving them a chance, or two..., to get it right. So still inconclusive at this point. I am likely to order the "tilt" to go along with the "top" he just installed, so when that comes in, he will pick up the tractor for free and go over everything again.

Besides curiosity, my (10 month old L5740HSTC3) LA854 has been less powerful than my previous GL5030/LA853. I discovered about 250 psi below spec on the 853, and adjusted that back to spec with shims.

I tested the 854 this AM and it measures just about 2400 psi, which is 370 psi below the rated maximum of 2770 psi (see attached).

I crawled under to find the relief valve to shim it, (I have the Kubota shim set) and after 10 minutes of "examine the photo, look at tractor, orient photo, look at tractor", I still could not find the relief valve as indicated in the photo .

Going to have to call my dealer.

I had the same problem with my 5030...best I can recall, photo is similar...underneath there is something that looks like a drain plug but when you take it loose...be very careful....slowly let it drop and also down will come the valve, spring and some washers (shims)....

That's my memory,....don't know if your 5740 is same as the 5030...good luck! I've found that a call to the dealer and talk with service manager is very useful and helpful. Good luck! I know that you will see a HUGE difference when you get the pressure brought up to spec!!

 

[RFB]

Hi John, glad to hear from you.

Yes, the 5030 was pretty straightforward when I did it, and I used a screen covered container as a shortstop to catch any parts.

The 5740 relif valve is in a different location...so far I have not been able to find it regardless of how I compare the photo to the underside. I am probably staring right at it and not seeing it.

I will try again this week.

RFB, you've been there, done it, you'll do it again
