oh my god. THANK YOU. i didn't even know what I didn't know. Super helpful.

You know, I agree with all of this. And you’re right about the different types of grasses. We lived in Florida many years back when mulching was being pushed. I smothered my front lawn by mulching and had to resod. A lawn man came over to help and told me not to try mulching. He always used a side discharge (he told me that the grasses along the freeways always grow and they discharge!) but to not cut too much off at a time. Now we live in Tennessee and I have an acre. My John Deere 54” does a terrific job of dispersing the clippings. But again, I cut often. Thank you for the video

The best lecture ever Mower PhD

I have the same problem with giant piles of guacamole flopping everywhere!

Thank you for the good advise :)

Discharge!!!

GENUIS !!

Nostalgia with the opening music! Original need for speed PS1 soundtrack! Edit: finished watching the video. I've commercialy cut for a decade. #1 rule. No matter if you mulch. NEVER use 3 in 1 blades. Poor design poor airflow. Even for mulching we used high lifts. High lifts are a game changer even for residential mowers. The vacuum is much more intense and will suspend clippings longer dicing them even more. If you live by the "⅓" law, mulching will be the best. Anything higher than the ⅓, side discharge if not too thick. The taller the grass, the less stress you want to induce, so bagging would be the way to go if it clumps on side discharge. You want that grass to exit the deck quickly when it's thick. Less mower stress, less bogging down. You are absolutely right on the vacuum theory if we can call it that since it was proven by a KZfaqr in slow mo. Even this advice may be enough for some, but it really help to know your grass type and dirt type. That will also impact how you mow specific types. You're on fire with this. Keep it coming! Most landscapers won't tell people about airflow, blades and secrets. It's science, but it's easy. Anyone who uses 3 in 1 blades, swap for high lifts. Your mower will be on par with a $7,000 exmark!!!
