I'm working on an X758 that has an autoconnect deck. When I got the tractor, the mower drive shaft was missing, and the auto-connect bearing housing was busted and dangling. I installed a new shaft, bearing, and bearing housing, and that all went well. However, when the lift arms are in the lowered position to mount the deck, the drive shaft maxes out on length, and the female coupler ends up pointing upwards, rather than being parallel to the ground as needed to align with the mower deck shaft. I'm new to this arrangement, but I'm pretty sure it cannot work like it is. Ideas?
