One of my neighbors has a set of mules he uses for farmwork. They seem pretty easygoing ocmpared to horses, they got out the other day and wound up in my backyard. I guess they wanted to help trim the grass
Brush clearing goats, that's where the money is. Get 20 or so boar goats, some electric fence, water tank, and a hut for them to sleep in.
Setup your fence/shelter/water tank and let them chow down. They even eat poison ivy
