hi, have a small hobby farm/homestead south of houston

i have a JD990 4x4 and would like to add rear hydraulics ..

in addition, i have a hesitation in my lift that i know is not my cylinders... maybe a dirty or worn pump

does anyone know of a shop that works on tractors and tractor hydraulics in the houston/south of houston area?

would be appreciated

any line on the power beyond kit BM18010 or something they are what they are selling now ..

thanks in advance for your help
