How big of a chain harrow can a mule pull?

[warhammer]

When the chain harrow is aggressive side up?

I'm guessing as big as you'd like. They aren't heavy.

Most folks use a 4 ft drag harrow behind a UTV but with the teeth up you could pull 8 ft easy enough

I built a CHAIN LINK drag, 8' wide, double layer chain link fencing for use behind my NH TC-40 but I also do pull it behind my 3010 Trans Mule diesel to gather distant brush piles. Drive up and stop, flip the top chain link over and forward, load the brush and flip the top chain link aft to cover the pile and off I go to the centralized gathering point.
