Thanks for the advice. Maybe I'll look into making a box. Do I need a drawbar and stabilizer bar?
You won't need a stabiizer, but it is a nice thing to have. Sadly, the best I've seen is no longer in regular production.
You could either use a cross drawbar,
available at your
TractorSupply
NOT this kind shown in the MX attachment.
Or you could just use the Cat 1 pins
available at your
TractorSupply
One more thing you will need is a Top Link
It, too, is available at your
TractorSupply
Lots of folks just cast the cross drawbar or pins, and the "ears" to which the Top Link would connect into a strong concrete cube. If you're adept at welding, or handyman construction, you could follow some of the other suggestions of building a box, then putting stuff like chains, tools, or even (what I intend to do) pavers in it. The advantage is you've made a multi-use ballast rather than a single-use cube.
Whichever you do, please keep us updated on the progress, and keep in mine Skeets' and other's incessant demand: "Pictures! We want PICTURES!"
