Greens units

Here I checking to see if unit is cutting paper this is single piece of paper place into between bed-knife & cylinder, I turn the cylinder making sure it turns easy and there is no contact with the bed knife, which means less friction, less effort on engine saving fuel, but to maintain this requires regular backlaping little but often is how I like to do it which would maintain cutting edge, disadvantage it's wears the bed-knife out requiring replace through the season.
