ga spares bnc3242 will fit both perfectly. Bruce should have them, as will and mower shop
Tyler, Thanks for that. Rang up the local mower shop, they sell GA spares blades for victa.
I was quoted $16 for the bnc 3242 over the phone, not sure if the bolt set was included.
Bunnings do sell victa blades for the 18", at $29.64. pretty pricey though.
Good to know that 1 blade size fits both of my mowers, thanks again.
