Hi, I purchased a 60" Lazer 5 weeks ago and I'm getting frustrated. It's not cutting all the grass. I have done everything... sharp blades (solid foil/high lift), tire pressure, deck level side to side, deck pitch (from 1/8-1/4), clean under deck, slowing down, and recently increased the RPMs to 3750. I do not believe the grass is overly thick or tall. My 6 year old 50" Gravely that I traded in for this Lazer gave a cleaner cut... I do not want to double cut every lawn all year round! How do I get a rep to come out and look at its performance??? Thanks, Tom Garvey TSG Property Maintenance Co.
