I was shopping for a new scythe blade when I found this beautiful and incredibly long competition scythe blades.

In the video, they seem to be judged not just on time but also on how well the area is mowed. I find this fascinating.

You could also just get a push mower (non-powered). Takes no skill to use.
A push mower might work if the area is flat and level. I tried one on my bumpy field and it was not a good time. A scythe with a ditch blade is so much easier to use in that scenario.
