I was trying to run doubles this weekend I had to catch up after 2 days of rain and no mowing. So I put high lifts on the bottom and Gators on the top. When I took off on my first yard ( Commercial) And started the blades and went at it. So after mowing I noticed these blades left grass standing in most areas of the lawn as if I went over it at full speed when I was going over it at a slower pace than normal. What gives ??? The blades are sharp and I had stacked the blades like this + It just landed up cutting much worse than normal. It was actually quite embarrasing.
