Hi Alex, Just a heads-up here, mate, you mention that you will be removing your reel for sharpening in winter time, well that exactly when all the greenkeepers will be doing the same.... Once the engineers set up their lathes for the large reels 30-36" they will not reset the lathe to do a small reel usually, until all the others are complete....and that can take literally ages. Now is the time to sharpen...However, check with your engineer.;)
