On monday the 2nd the cam broke on my walker so while i was waiting for parts i demo a John Deer mid-mount . It had the mulching kit in it and oh boy was i impressed. When you turned on the blades it was ready to eat up some grass. I couldn't tell that the lawns were mulched with only single passes. The next day demo a 44" Toro walk behind with mulch kit installed. I was disappointed in it. Didn't sound like it had any blade tip speed, left a trail of grass on the right side and had to double cut some lawns.
