I have a JD 320 skid loader I have had for about 3 years. When I got it (used) the directional levers where hard to operate. They are extremely stiff and seem more stiff than when I first got it. I also have contol levers for the lift and curl that are also extremely stiff. I have heard a couple of other owners say this is normal but, would like to ask others if they have had the same problem and if anyone knows of a solution. I have Bobcats and Cat skid loaders and they are very easy to operate so I know its not normal for skid loaders in general.
