My customer purchased a Toro Super Recycler with all the bells and whistles, I went through the operation with him. A few hours later he called back, seems the lawn didn't look any better after he cut it. I went to the house and looked at the lawn and the underside of the mower which was clean. Hmmm. I started it and
engaged the blade. "Oh", sez he, "I didn't press that lever". He seemed bright enough.
