I've got a Zero turn mower that I tweaked the engine a bit, and I replaced the turf tires with ATV tires. Typically I can mow fast enough to avoid wearing the lawn- depending on the wind direction that is! You should see the bald spots around trees and stuff- I don't slow down at all, so it's starting to build up a small burm from the pushing through the curves!! LOL
Buckle up- I wanna try something!!
