I have a Frontier GM2060 attached to my 1996 JD 955. Due to having multiple implements I purchased a Titan Quick Hitch. I had to purchase the JD/Frontier Quick Hitch adaptor for the GM2060. On level ground I lower the mower so there is clearance between the mower driveshaft and the Quick Hitch, it works fine. When I am mowing on a hill where the ground has humps and hollows, I have to keep moving my rocker lever to maintain the clearance between the driveshaft and Quick Hitch. If I am not paying close attention the Driveshaft and Quick Hitch rub against each other and I need to adjust before any damage is done. Any ideas on how to fix this problem. I am about ready to remove the Quick Hitch whenever I need to use the Grooming Mower. This is the attachment that I use most often so this will be a pain.
