I purchased a used BX2200 and I believe the lever that lifts the 3pt has never worked correctly. When I got the tractor, it would raise and lower the 3pt, but it would snap back into the full up position, I used it by keeping my hand on it to prevent that, but now decided I have to do something, it's somewhat dangerous. I searched all over (I have the WSM manual) and couldn't find any detailed instructions on how to adjust it. I tried to adjust the nuts on the rod to a neutral position, but now it won't go all the way up. Any advice would be greatly appreciated. Thanks.
