Cox 12HP 09M7 rode on - cutter brake, mystery part

[GungHo]

I have a wonderful one owner (before me) example of these, which ran perfectly until I hit some bricks hidden in long grass. The deck came up rapidly with the handle whacking my right leg just below my right knee.
It did some damage, with the brake arm now fouling the side of the cutter pulley when the deck is down, and when up, the brake pad arm is a long way from the lower face of the pulley - and the brake pad has gone.

Of greater concern is the piece of metal found on top of the deck - 8.75: long, holes 7" apart, with witness marks each end. I cannot see where it has come from.
Can anyone please point me in the right direction for fixing this, and identifying the mystery part and where it might have come from?
Many thanks,
Doug (Brisbane)

I'm pleased to advise i have been able to answer my own 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 through the engine deck and screw into the plate. 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. So lucky it fell into the enclosed area on top of the cutter deck which has 4 metal sides.
Cheers
Doug
