Exmark, I am new to this forum and new to Exmark. I bought this old Exmark Lazer and it does need some work. My biggest issue with it is that when I am mowing thicker or taller grass, the blades slow down to where the grass is not being cut and I have to go to an area of the yard that is already cut and let the blades get back up to speed and make another pass. I'm just a homeowner & I don't have a dealer close by that could look at it. Any suggestions are greatly appreciated.
