Spacey, trust me I like to see the Darwin award given, just doesn't happen often enough without innocents also copping it.
Mowers, is yours self propelled? They often have the dead mans lever. You can always strap into the on position and add a switch if you want to stop it etc.
Yes I hate the dumb mower switches, my brush cutter safety switch is constantly turning off as it is too close to the throttle. On the damn mower it gets turned off if you go under a low tree or brush.
Biggest piss off is ones with a see through pump bulb on the carb, they rarely last a year. Then spew fuel everywhere. Had a Stihl once that caught fire whilst in use from damn cheap bulb and non tygon fuel lines. Burnt my arm, all for a few cents saved making it.
I was once a small engine mechanic, some where so shit they died on first use and we just threw them away as cheaper to replace than repair..
For hedges get a smallish portable trestle under $200 and walk along in safety, falling from ladders six. Once fell two stories, it really .......hurts.
