Please help: Removing Reverser Lever on 6441

Can anyone direct me to a parts diagram for the reverser lever connections? I have an 05 6441 and the reverser lever just sheared off today ??? It has been unusually cold (-20 or lower) but I'm surprised since I've never had to force the lever I can't understand how it weakened. I'd like to see a diagram so I can better understand how to disassemble and what part(s) to order

You must take out the panel between the floor and the seat platform. the panel of wich the garlever comes out of. then you will have to take of the lump wich all the gearlevers og into wich sits ontop of the gearbox. when youve done that you wil see the rest of the piece you broke off.
