Yeah, Stevens, that was me in your link, back in 2013. My 2310's now on it 13th winter; think I've been through 4 or 5 blades for the 2360 now, currently experimenting with some UHMWPE.
For those who prefer to use the OEM steel blade, here's a tip: buy one from a Kubota dealer -- quite a bit less expensive, I've found, at least around here. RAD Technologies (in Canada) makes the blowers for Massey, Kubota and I think New Holland; I have a Kubota dealer about 1/2 hr away but the nearest Massey dealer is 1-1/2 hrs away. Not sure what the current Massey price is, but I was quoted less than $50 last week at my "local" Kubota dealer for what they call the "Cutting Edge" -- Kubota part #70060-03528. Same thing.
One thing in favor of the OEM edge -- it must be hardened steel; I've used locally-made mild steel blades and found they didn't last nearly as long (but at least they were 1/2 the price).
