When you get up to the 15' wide rotary cutters I have to ask: Why?
It looks like you are cutting a LOT of acreage that way. What is the land use? Are you maintaining low growth for livestock? If not, why not hay the area?
Just curious...not trying to ruffle feathers.
I do ~5 acres with my 6' cutter right now. 1 of those acres will be pasture within the next year or 2 for my goats so I don't want it over growing, but I haven't gotten around to fencing it. The other 5 are areas with trees that I just don't want turning into brambles and low growth woods. Not sure "why" but I just like it better this way.
If I had 10-20 acres or more that needed a 15' mower, I would be looking at hay.
