I am trying to be open minded...But....... A friend has a Tiger Cat II 52" cut. He just discovered that his yardman has been putting the mulching blades on upside down. I saw him take the blades off and all three had grass clogged up in the slots of the mulching part of the blades. The yardman told him the blades cut better this way. Has anyone ever heard of this? Thanks for any responses.:confused2:
