Hello, I have just gotten a john deere 410 backhoe. The hoe works slow, doesn't have the power to dig at all and the loader takes a very long time to lift. I mean you can hardly see it move. I have checked the sump/pickup screen and it was a little dirty but didn't change the operation at all. I am leaving toward the hydraulic pump as the problem but was wondering if anyone had any other ideas. Thanks in advance
