If I were to just mulch cottonwood leaves into my lawn with my Mini-Fastrak, would it kill my lawn? If so, why? If it was because of acidity, couldn't I just Lime the lawn to correct the pH? I wasted $450 on the top-o-the-line Stihl backpack blower, and found that the leaves don't just follow the airstream, they blow every which way-360 degrees! I gave up on that after 6 straight hours. Sold the blower 1 week later. The only rear bagger for the Mini-fastrack 36 costs $500.00 and it's 2 bags are so small, they would have to be dumped 40 to 50 times each...I won't be doing that either! I've heard of something called a "lawn vac" that you can rent, but if all it does is vacuum them up and spit them into a garbage bag, I might as well just buy the above rear bagger; it would take just as long In short, the fastest, easiest, and cheapest solution would be to just mulch 'em....unless it would kill the lawn. Your thoughts????
