Bucket will not retract .... loss of power

[rk137]

Hi ...

Lamborghini tractor....(Made by SAME. Because it was going to Switzerland it was sold under the Hurlimann name. w/ Koyker 160 FEL

1) Whilst moving some logs on my LARGE compost pile, my tractor w/Koyker 160 FEL and I slid off which made the loader slam quite hard onto a blackto surface. Since then my loader bucket will not retract. It begins but then stops.

I noticed that on the joystick, all of the plungerss move except the suspect.

Perhaps (short of breaking a seal) it intoduced air into the system.

How do I bleed it?

2) Also have a bigger problem. My under 200 hour tractor suddenly (without known event) has about 1/5 power. I just have no power to even pull across level land. The PTO has plenty of power but moving the tractor itself is very belabored.

Any idea .......and I thank all in advance.

I'm not sure about your tractor's power, but the FEL not working may be related to the hydraulic quick-connects. The shock probably caused one to pop loose. Your symptoms sound just like when a quick-connect unseats. I'd disconnect and reconnect to see if the problem goes away.

Hi,
Thanks Jim, I will try it Friday. I guess you are refering to the quick disconnects on the back above my 3-Pt. I do rememebr awhile back my lines shaking which might mean air.

Where would be the best place to bleed my system?

I am also tearing apart 2 Gravely GMT 9000 I used at my house. If you know of anyone that need s parts, wings or engines for those, please let me know.

Thanks again for your help. Do you think that air could cause power to wheels being diminished?

I was actually talking about the quick-connects that go to your loader. If those are in the back, then I'd try them. I believe most compacts have a quick-connect manifold other than the rear remotes, but your tractor might be different. Where do you disconnect the loader when you remove it? That's where I would look.

You may have done some damage to your hydraulic cylinders when you hit the pavement. If the hydraulic rams are only slightly bent, they would be hard to see. This could cause binding and no movement also. The quick connects are an easy check and something to eliminate before looking for something more serious.

Most times you can bleed a FEL's hydraulic system by just cycling the lift and curl though their complete range a few times. That's all I ever do with mine.

I don't see how the power to the rear wheels could be reduced by the hydraulics. If your pump was working harder than normal, it would bog down the engine and you cold tell it all the time, not just when you tried to move. I'm just not familiar with your tractor enough to make any suggestion about that.

I'm guessing that you rolled the tractor off the pile and it landed on the right side (as determined by sitting in the seat). Yes?

If so, you may have bent the linkage to the hydraulic control valve causing your problem. Or it could be a loose quick connect. They are used on some tractors at the control valve or in the system feeding to or from it. Check them all by following each hydraulic line on the tractor and disconnecting / reconnecting every quick connect found.

(It really can't be air causing the issue, by the way. The hydraulic pressure will easily force the air out past the seals or back to the tank.)

On the power. I am assuming that it was good BEFORE the accident and bad AFTER. yes? If so, you may have caused a small crack in the fuel filter, filter housing, clear end, a fitting or line. When needing more power, it draws a vacuum and sucks air in. That will be harder to find! Sucking air in is easier to do that liquid going out by the way. There may be a very small amount of diesel at the site. Check very close. Wipe it and degrease to help spot any new leakage.

Good luck and as we say, "Keep the greasy side down"!

John, your post reminded me that if it is not a stuck linkage for the bucket retract function, perhaps there might be a small crack in that particular hydraulic bucket function line which draws air. Along with something a little out of whack, it could bind and be enough to cause loss of function.

Regarding the the loss of power when moving the tractor, if the PTO has plenty of power then the engine is good and providing adequate power. I assume you checked your PTO power under load to determine it, in fact, does not bog down? If it does, John may be right about his analysis. But if it doesn't bog down under load, I'd be looking for something bent or the brakes stuck or something that prevents the tractor from rolling freely. Just a thought, did you try moving it, pushing or towing it in neutral to see if it's bound up somehow?

I'll bet you bent a cylinder rod.

Don't worry about bleeding cylinders, they self bleed.

BUCKET FIXED SOLELY DUE TO YOU!
YOU ARE THE BEST!
I AM SO GLAD I FOUND YOU GUYS!

1) Bucket: WHILE CUTTING SOME GRASS AND THEN NEEDING TO WAIT BECAUSE OF EXCESSIVE OVER-HEATING (ANOTHER PROBLEM) I GAVE THE QUICK-DISCONNECTS A CHECK AND THERE IT WAS; A QUICK-DISCONNECT DISCONNECTED. I PLUGGED IT BACK IN, BUCKET TILT SOLVED!
THANK YOU: jinman, jinman (again), john bud, 3RRL and Wayne County Hose for all your comments and help.
I mentioned that I have 2 Gravely GMT 9000 plus many parts for them and 2 Continental engines and spares. If anyone needs any parts I shall be happy to give the best deal ever for whatever they need.
2) Power Loss: As stated, the bucket problem is a recent problem but last year, for no obvious reason (no it was not due to the bucket mishap) I have lost about 70% of my power. I have not checked per the suggestions thus far but if any of you have any ideas I could check please let me know.
I was cutting the center (dead flat) moved to the right front yard which has a slight grade. It was then I noticed I can barely make it up this grade. The rear PTO has good power but the tractor can barely move itself.
3) Heat: As stated, the only other problem I have had is the over-heating. Perhaps I need a new thermostat or sensor? Having used one in my car, I am thinking of installing a 4 small fans, 2 on each as there is not much space between the radiator and the back of the fuel tank.
I hate to ask you guys for even more help but if you have an idea, I would love to hear it as the dealer for this tractor is about 70 miles away and is not very generous in helping.
The real killer is its guarantee was 2 years or 1200 hours. I just turned 200 hours but bought it about 4 years ago. It always ran a bit hot.
Other than those problems, I love this tractor.
Again, THANK YOU so much for all of your help!
Rick

What a thrill it is to know that I've been able to help with at least one of your issues. Thanks for posting back.
