I recently purchased a used 20 in McClane reel mower and I tried it out for the first time today in my back yard. When I bought the mower I knew that I was going to have to get the reel sharpened, but I think I may have another problem. I was cutting on a very level part of my yard and it seems that the mower cuts to high on the right leaving an unlevel cut. Is this a normal problem with reels? This is my first reel mower so I am kind of a rookie. Any help would be awesome.
