NAA Hydraulic Lift

Michael Lacey Hooked up some weight for the first time on the hydraulics (vane pump). I noticed that when i lifted the hydraulics, it would "step" up versus one smooth lift. It was somewhat choppy. Is that normal? I read elsewhere on the N series that you may need the PTO engaged for the hydraulics to lift any weight properly - is this true?

thanks guys.

mark sr My NAA has a piston pump but I don't have to engage the PTO for the rear lift to work. I usually have a 6' scraper blade on the back so it has some weight. My hydraulics aren't choppy, have you checked the fluid level with cylinders extended? What does the oil look like? might benefit from changing it.
Michael Lacey Changed the fluids last year per the spec. I get some dripping out of the pressure line from the vane pump, buts its very little.

I'll have to verify the fluid levels again, but it is good to know that i do not need to do anythign special in order to lift weight. When its empty, it goes up smoothly.
