DK4510 2485 Backhoe Lacking power

[Grant1]

I have a DK4510 with a 2485 backhoe attached which seems to lack power on breakout force. I have also owned a ck30 with a 2375 that actually seemed to have more power with the backhoe. I really noticed this yesterday trying to remove palmettos running at 1800 rpms. . I also could not pick up the corner of a 4" concrete slab driveway. The backhoe digs dirt fine but really seems to lack the power on other uses. Thanks in advance for any advice

If your loader works fine, I would assume the tractor hydraulics and its pressure relief valve are set right. The bh itself does have its own pressure relief valve. You'd have to attach a gauge to a hyd line, like the dipper or bucket curl cylinder on the bh, and see what you get.

I have a similar issue. Had a CK 25 w/2475 backhoe. It seemed to work fine. In 2012, I traded for a DK 40SE w/cab and a 2485 Backhoe. I find that the boom seems "weaker" than the smaller hoe was. I had the dealer come out and he put a guage on the cylinder. Pressure was almost 3,000 lb, so we put the return line directly into the filler tube. (there's a kit for that) It is better, but it's still just doesn't "feel" right.
