I went with the 48 inch Lazer HP and the 20 hp Kohler, this thing scoots! Couldnt wait so I went out this afternoon and mowed my 3 acre field. I did jump the belt off of the right side though, I engaged the blades at full speed, is this what caused that? I know it says to engage them at 1/2 but I wasnt thinking. Love that gas gauge and 11 gallon tanks capacity! I never knew these things could cut high grass so good. Now I know why everyone raves about these mowers!
