Hello.
Quite a lucky find. If you can find the extra blades you'd be on to a winner.
I am looking to build a groomer out of a spare SB45 17" that I have.
I'd rather not pay $3.5k for a Protea 25" Groomer. 37 Blades at a guess of $25 for each blade would get me $925 Groomer plus the satisfaction of doing the modification.
I have been looking for those blades everywhere. Any information where I could purchase these blades would be useful and much appreciated.
