goat/miniature horse/pony walk-behind cultivator

I am toying with the idea of getting a drivable animal “helper” for cultivating. Has anyone used a small cultivator like this with goats? A back-of-the-envelope calculation tells me that two large goats would cultivate better than one. Tim’s draft data says a single row horse cultivator takes 85-135 lbf (110 lbf average) to pull. It cultivates both rows, though, so I cut this in half to get an average of 55 lbf for a single row. This is 12% of 450 pounds, which might be the combined weight of two large wethers. Given this, one goat (based on it’s body weight) seems margional for cultivating a single row, but I have seen photos of single goats pulling cultivators… All I know of this is what I have seen in photos, and do not know anyone that does this so do not know if using goats for work like this is really practical. I do like the pasture improvement and weed eating bonus that goats provide. I have also read that because of thier browsing, one can pasture a few goats with cattle and have little or no impact on the amount of cattle the pasture can support. This makes sense to me too and I have really gotten into pasture improvement lately.

Thoughts anyone???

Thanks for thoughts, Jean. What would you guess you mini weighs? Was it an easy job?

PS. I would consider a mini, too, but an kinda enjoying my current horseless lifestyle. The other animals are so much less work. 🙂
