i bought the 850 john deere i posted about a week or so ago, it pretty much works as it should, but has been run hard and put up wet, some cosmetic damage which isnt a big deal, some day i may fix that, several minor hydraulic leaks, most on the loader cylinders, but one curious thing is it seems to take a lot of rpm to run the loader and backhoe, by a lot i mean mid range on the tach, is this normal? it has a adjustment under the seat which im assuming is hydraulic flow, i have it wide open now, most of these little tractors ive run [ kubota, and ih 284] seem to have very quick hydraulics, im ordering manuals for this one, but need to use the tractor now, any advice or help, or is this normal operation for the tractor, hour meter shoes 24oo hours so it shouldn't be worn out
