Who makes a flail for an ATV?
Alamo -- the same people who make the ones seen along roads and in parks, except with a gas engine mounted on top. They had stopped making them just before I bought mine (2001) but I found two at a warehouse in Bradford, PA.
Before buying I had exchanged info at ATVing.com with guys who use ATVs in landscaping businesses. They all said the Swisher-types just tear themselves apart so I went looking further. A neighbor in the country had a flail mower and liked it (but lost it in a divorce) so I thought it might work for me.
But as noted above, it just hasn't worked well in my situation. I put a ball hitch on it, got bigger tires, and installed anti-scalp rollers but it still is not the right tool for the job.
Also, I think I can safely say that an ATV makes a poor tractor. The main problem is keeping it at a steady pace -- its either surging ahead or bogging down, plus your thumb gets tired, the engine gets hot, your back hurts, your neck gets sore from looking behind, and so on.
I rest my case.
Thanks,
Rod
