My sheep ate them as far up as they could reach, but the briars went to the tree tops. We machete chopped the bottoms and dragged them out of the trees. Once on the ground, the sheep swarmed all over them. The young sprouts are actually quite good, I used to snack on them, but there aren't many left here now. LOL I have even gathered the shoots and saute'd them in butter, taste like asparagus. But I don't like them enough to keep green briars around for snacking on. Overall, I HATE THEM!i think sheep will eat that too? but you know for sure that goats will.
I am certain the full day's work will be rather expensive-not $100. But you are definitely correct about the cost of the machine. That was just a rich woman's dream. And I not a rich woman. hahai think i have the best of it here @catjac1975 as the neighbors have one and he said he'd come back anytime we need it done. we don't have enough property to justify owning such a machine. renting one for $100 every five years is perfectly acceptable to me. at first he only wanted $50 but i gave him $100 because i was so happy with how much work he did and how much work it saved me. when he was done brushhogging what he could get at with the deck he had another neighbor go over to his place to get the backhoe and then came back and knocked down and removed some of the large honey suckle bushes that were growing in and along the banks of the ditch. that saved me a ton more difficult work (working the on banks of a clay slope). we waited 20yrs to have it done the first time. i was surprised by what he was able to do with just running over things with the tractor and brush hog.
the gadget that @baymule had those people run over her brush covered areas is even more impressive. pretty much instant mulch...
in a meandering mood...I think it has to do with it getting lubricated regularly. Seals tend to dry out. Fuel can dry out and leave a residue behind. That's why I own some electric stuff, not gas powered. I don't use it enough to keep it working correctly.
