G'day folks,
Picked up a blade plate with new thrower blades on it which will be fitted onto my nice painted one. I was surprised at how bent over the blade is to enable enough air to move the grass into the catcher.
Paul, what you have picked up there is a pair of P/No 9-152 thrower blades intended for
side discharge use. Pretty rare item these days!
The rear discharge thrower blades [P/No 9-174] were a more conventional 45 degree flute, and have only recently been discontinued, though a few online/eBay sellers still list them. Search for P/No CA09174S to find those.
The cutter blades, P/No CA09150S, are still available, as are bolt/nut/washer sets.
