Purchased a 52" Great Dane Surfer this spring and have really enjoyed the time I've saved. This thing is built like a tank. The problem is that I'm getting all kinds of stragglers, for the lack of a better name. Tall shoots that just don't seem to cut unless I'm mowing slower than my old snapper mower. Did a search and its seems maybe I should go to solid foil blades but haven't been able to locate any for my mower. Looking for any other suggestions which will eliminate double cutting. Oh yea, blades are sharpened once a month and I only cut an acre & half once a week, thats about 6 hours. Thx!!!
