Turned in my demo on Friday morning. WOW WOW WOW ... This machine outperformed my current mower by leaps and bounds. Yards that were double cut all spring aren't any longer. Yards that were scalping around certain areas are not. One specific spot I did scalp was at the base of a 25 degree hill, around several trees. Fortunately it was in my own yard, and I wanted to test its limits. It went so well, that I pick up my new 48" tomorrow !!!
