I did something like this once but kept the regular grass cutting blade. It did cut down tall grass BUT also sent the clippings right back at my face. NOT good.
I worked for a small company for a bit, 29 people. They had gone public shortly before I joined. They had a dispute with the president and some how ended up ousting him and replacing him with another. The first president had some iron clad contract so he was still being paid. No idea how that worked. They bought a limousine for the company and also had 5 VP level people as well as a marketing manager. They weren’t doing very well so they hired a consultant to tell them what was wrong, (duh). He said the biggest problem was 15% of the TOP line was going to their two president’s salary. What did they do? They fired their 4 sales people. True story. They were gone shortly, bought out by their main competitor.
