Problem Back Blading With The 200CX loader On My JD 2520

coollx · Jul 22, 2023

Need help determining why all of a sudden there is no hydraulic pressure when I try to back blade with the 200CX loader mounted on my JD 2520 tractor.

Bought the tractor new about 12 years ago and it has always worked fine. The hydraulic fluid is full and has been changed as recommended. The loader works fine when lifting, carrying, lowering and dumping the bucket with heavy weight in it.

With the tractor running and the bucket raised and tilted downward as if to lower it to back blade material, when the leading edge of the bucket touches the ground the bucket simply returns to the level position on the ground with no resistance.

I would appreciate input and your thoughts on what might be the problem and how to fix it.

Thank you.

@kennyd would this be a symptom of the JD droopy bucket?

Yes, but these models never really had that issue. I'd suspect the piston seals in the cylinders are bad, not an uncommon issue with them.

Try reconnecting the quick couplers, see if one is not fully seated.

That's exactly what I found to be the problem with one of the bucket quick couplers.

Problem solved!

Thank you

I agree, just disconnect and reconnect all the quick couplers. Might not fix the problem but an easy thing to check, otherwise I’d say the seals are going bad.
