This weekend I ran into a huge problem with our 8300. The 3 point would not lower. My uncle told me that he has had to pull it down to use it before but now it will not move down. While running it this weekend I see that the AC condensate drips in the left side of the lower three point arm. My uncle told me that when he sprayed that area with WD-40 it would work. We assume it must be a rust issue? I sprayed all the areas down with pensol but I have not make it back to test anything out. Any ideas?
