Thanks Bruce, it's way beyond shiny, its heavily striated - circumferencial grooves in both sides of the blade plate, and the center hole in the blade plate has become so enlarged I've had to use a small centering bush. The blade plate is some kind of turbo type - complicated pressing with a major flange around the outside, and recesses for the blades to swing back into. It creates an awesome draft, and really packs the grass into the (unfortunately rather small) catcher. It didn't come loose mowing foot-tall wet kikuyu at 35 lb ft bolt torque a few days ago, and I'm hoping it will now rust a bit and settle in. If it moves again, I will have to take more serious action. Are those turbo blade plates available?
