Thanks Max.
I spent some time on it this morning and have answered both of my questions, as follows:
1. The reason for the odd configuration of the cutter brake bell crank was that the threaded rod that goes to the front of the mower and back into the U piece that attaches to the top of the bell crank had been pulled so hard the spring had bound and the end of the rod had been pulled out of its hole and was jammed against the cross piece. Easily fixed once it was out.
2. The plate with the threaded holes is an Engine Mounting Bolt Plate. The engine mount bolts go down beneath the engine deck and screw into it. Need some Loctite for next time. If there is enough clearance I'm going to get longer bolts so I can put Nyloc nuts on so it can never vibrate loose again.
Cheers
Doug
