Where is a good place to get blades for a victa 550 and for a greenfield I.P.D. Slasher. I am also getting a 560 hoping its here this week is it the same blades as the 550 and where do you think i could get a 4 blade blade plate i got one off the dealer here when i brought the 550 but i have since decided i dont really want to deal with him any more i think i have been over charged on a few things and last repair i belive should have been under warranty and it wasn't.
