Agree with the rest: what you need are goats. Not sheep. Ever see a golf course? They are designed after sheep pastures. That's what a sheep pasture looks like: perfectly trimmed grass. GRASS. Goats on the other hand adore eating things with stickers and thorns and will eat things with total gusto that would actually kill a cow. If they can stand on their hind legs to eat it, so much the better which means junk trees will go too and you will need to protect good trees as the goats will peel the bark off them. They will NOT trim everything down perfectly. For that you need a mower, brush hog, what have you. But thickets of pasture rose, blackberries, thistle, black locust etc. they will eat that. Amazingly enough.
And yes, goats do not smell. Buck goats, **while they are in rut**, do have quite the odor. This is to entice females and warn away other bucks. To their way of thinking, the stronger the smell the better. But your normal average goat does not smell. Come to that, rams (male sheep) ALSO can smell when they are in rut although it's not as common as with goats. Having sheep does not solve the odor issue.
Now, there ARE breeds of sheep that are very primitive and will eat at least a little brush. Nothing like a goat, but close. I used to have Jacob sheep and they were fairly good at this. I still think what you want are goats, though. Most goats don't need to be sheared, but there are sheep breeds like this too... not the Shetland, though, they need to be shorn once a year. Do you have a local Ag extension office? Ask them. They will know what will work in your area.
