My Cub 124 is all original except for the battery and although it can pull 10 times it's own weight with just turf tires, it is starting to show it's age. I was backing up a trailer uphill that was over 2 tons and the shifter kept slipping out of reverse. It only did this in reverse and never in 1st. So I know I need to remove the shifter cover and inspect the shifter fork but I was wondering if anyone knows the exact procedure to fix this problem, has a link to detailed instructions, or better yet, has a link to a video showing the removal of the shifter? I know there is google and youtube but surfing those sites for the exact info I need often takes the better part of an afternoon and I really can't stand sitting infront of a computer if it can be avoided. I'm not very fond of computers and sitting for long periods of time just upsets my disc problems. I just don't want to create more work for myself by removing anything I don't need to to access the damaged parts. Any insight would be appreciated.
