    Swing is not designed to move objects or level out piles. How long does the upper structure continue to turn after you release the controller?, 1/4 turn? 1/2 turn? You may have low swing pressure. Typically swing is set lower than dig pressures. You also may have a weak swing motor.

    JD 310A won't pull forward

    yes, what melben says is correct. The 310C uses a borg warner reverser unit. No need to split the tractor for removal of these units.
