John Deere M 1950

[M Thompson]

hey everyone " I have a JD m 1950with a lift arm problem, just got the tractor at a sale and lift arms didn"t work rebuilt the valve body ( it was really dirty)cleaned everyting and installed all new soft seals, tha lift works fine now except when the handle is pulled back to lift the arms, when the arms get to that height they go up and down a few inches and keep bobing up and down , any ideas would be greatly appreciated Mark
