I mowed a neighbour's lawn which had grown to two foot tall throughout, and my 1980s Mustang with thumb latch catcher did it all slow and steady. His green waste bin couldn't take all the clippings, so I brought mine over!
This mower ran on straight petrol once, thanks to silly old me mixing up the fuel cans, and seized up mid mow. I just let it rest a while and fed it the right fuel and away it went continuing to muscle though thick growth as needed.
It probably has some awful scoring on the poor piston and bore!
