I'm curious. Do the current line of flail mowers drive the cutter drum at PTO speed or does the gear box over-drive it? I've noticed that most have only one drive belt. My flail has three drive belts but I suspect that's because the larger drive pulley over-drives the drum pulley about 2:1 or there about.
In fact, its upper pulley outer diameter is 170mm, its lower pulley outer diameter is 120mm, so its ratio is 17:12. This mower is called EFGC flail mower in China Alibaba, you can find many of them, but it is difficult for you to identify if good or bad.
