Exmark Viking Hydro 48" Hi-lift blades Newly sharpened Height set to 3 1/4 and tried it at 3 1/2 Having a problem with leaving single blades of grass while mowing thus causing me to have to double cut. I have tried going as slow as possible but it is easier to go faster and then double cut. On a bright sunny day with the wind blowing, you can look over a freshly cut lawn and see the single blades all over the lawn, and they seem to 'wave' at you, kind of laughing at you because they are still sticking around!! I don't recall the deck position but the blades have one spacer on them.... Does anyone have any advice or has anyone seen this problem before? tia, Tim.
