J Mech: Thanks for your help and schematics. I spent the day reassembling and attaching the lift handle and its push rods to the 3 point hitch and the tractor. As I stated before, I was in the process of removing the drive shaft / clutch apparatus from below being erroneously informed that it was a simple operation(wrong). In order to get to the parts I had to remove the cross bar holding the lift handle and the foot pedals. I didn't take enough step by step pictures and I kept blindly removing nuts and bolts to loosen the apparatus out of my way, then some of it fell out and I didn't record their arrangements/ order.
This info is for anyone who might be ensnared as i was. I had to trial and error several times till I got the reassembly right. The #s refer to the schematics you provided above.
1. The #9 (u shaped bracket) has to be placed first outside or lateral to the lift handle.
2. The #8 (ratchet tooth semi circular) bar has to fit into the narrow clef of the lower part of the lift handle above the handle locking pin.
3. Secure the lift handle/cross bar to the rt and lt of the frame using the triangle pieces #10. Especially if you are doing this alone, without extra set of hands.
4. Then bolt the bracket #8 and #9 to the frame.
5. Then slide #3 (rotatory section of the long #4 shaft) into the bottom of the lift handle just above the cross bar and secure it with 2 bolts.
I found this step by step sequence was necessary because the individual parts did not allow manipulation to gain their needed position.
First 3 photos denote #8 #9 sections.
Next 2 denote #3 #4 attached to bottom of lift handle base.
Hope this helps someone in the future doing what i did.
