I don't really want to enter debate on this issue as we've all been through it before, but here is my two-bobs worth.
I have discussed this issue with many greenskeepers, and none of them advocate 'relief grinding'. However, their machines have the capability of being able to reverse the reel by turning it over 180 degrees and re-installing; whereas the 'back' edge now becomes the front edge.
With a Scotty Model 45, this is impossible, because of the reel design.
Any procedure that removes a lot of metal from a Scotty reel in my opinion is to be avoided at all costs.....at almost $400+ for a replacement, it is more than the cost of a second hand mower in most cases.
I rest my case.
