I read a post from this site suggesting to change the hydraulic oil in the drive pumps from high velocity to low velocity. My John Deere dealer changed the hydraulic oil and filters. It worked to quiet the pumps and made the sticks more manageable. Thank you for the advice. Question: On inclines, the right side of the JD is light on the right side and spins easily. Weights can be purchased from John Deere. Has any one had any success with the weights maintaining the traction on inclines?
