Ten years of packing mules in the wilderness taught me something about how to raise my triplet boys -- and seems to apply in this case.
There is no way I, at 220 pounds of a bunch muscle (those were the days!), could force a 1200 pound mule to do anything it did not want to do. It was a matter of getting the mule to believe that what I wanted him/her to do was also what the mule wanted to do...and to perhaps adapt what I wanted to do to with what the mule(s) wanted to do.
Good luck in the processing, the results and with the family!
