That's nothing. You should see what I've done to my Toro mower.
I left out the grass catcher, cross drilled the wheels to save weight.
Changed solid rubber tires to nitrogen filled pneumatic tires. I have no idea what this does, but all the race guys do it. 100% nitrogen is very expensive, but 70% nitrogen is free.
Added Japanese character stickers for mods were not really installed. Felt like 10 hp stronger.
Added ram air intake 1/2 inch above the grass, took out the air filters because it kept getting clogged.
Added carbon fiber veneer to the handles. Felt noticeable improvement to stiffness. Carbon just looks faster.
Took out the self propel and belt to reduce drag and weight. It goes as fast as I can push. 4.3mph is too pedestrian.
Thinned out the aluminum deck to 1/16" thick.
Got a lightweight flywheel for the motor. It doesn't idle very well, but throttle respose is very quick
Ice chill the fuel tank. Dense fuel makes more power.
End result: Shaved 30 seconds off my lawn mowing task.
The lawn looks really bad, uneven cut with stragglers everywhere.
