So, I'm cutting an account today and I was just finishing up with the mowing, getting the trimmer ready. The customer comes out and asks me to cut it shorter. I told him that I have just finished cutting, but I will do it for an extra charge however I will not scalp the lawn. He says ok so I fire up the mower again, drop the deck down 1 inch and start cutting. I'm cutting the lawn, grass flying everywhere, neighbors looking at me thinking "What the hell are you doing?". I look forward and go as fast as I can. Finish up, lawn looks terrible so I take the blower to spread some clippings out to make it look nicer, clean his driveway and his neighbors driveway since they both have grass clippings on it from me. I'm in and out in 45 minutes, I charged him $75. He accepts and pays me on the spot. Now, my main question is do any of you cut shorter for the last cut? This is the first time Ive done it and was wondering if it benefits the grass at all... Thanks.
