No matter where the land is, i.e., ten feet away from your patio sliding door or hundreds of yards from the nearest house, there's a pretty important, as well as breakable, item sitting five feet in front of the rotary cutter......YOU! Not to mention the tractor itself.
Last summer I used the toothbar on my FEL to rip out a short forsythia hedge. When all five bushes were ripped out, I had a rather large pile of debris, I backed into the pile with my Woods BB60. Little pieces of forsythia were flung out in all directions. Not a lot, but enough that if I had been chopping up anything thicker, I would have installed a chain guard.
