How to rid your lawnmower of evil
Premise #1: Consumer lawnmower blade speeds have been limited to 1000 RPM for many years due to lawyers and insurance companies.
Premise #2: Lawyers and insurance companies are evil.
Goal: To rid my lawnmower of evil.
I decided to simultaneously clean off all the crud that was caked on the bottom of the deck. There was a lot there.
Then I sandblasted the deck to get all the rust off.
I used POR-15 to paint it. It's kind of like a brush on epoxy paint.
Now for the smaller sheaves.
I decreased the diameter by 30%, which increased the speed by 30%. It took a lot of trial and error to get the right belt, but it worked. It takes a little longer for the blades to get up to speed, and the engine bogs a little in the thick stuff. I guess the engine will need some tweaking this Winter. : )
