"I've got a lot of private data on these old disks," the man says. "I better get rid of them to make sure no one sees what I do on my computer."
The man uses four Chronos high speed cameras to record as he sets off the mechanism that dumps the disks one at a time into the lawn mower's blades.
The video offers multiple views and speeds of the disk destruction.
It soon becomes clear why the man wanted the disks destroyed -- they bear labels including "Windows 7 disc 1 of 2794," "Porn.jpg," and "Furry_Porn.gif."
The YouTuber reveals at the end of the video "why no one is allowed in the room" -- a piece of floppy disk was launched by the mower at a speed fast enough to embed it in a wooden board.
