[TowerTalk] Using riding mower to run radials (2nd Try)

[Dubovsky, George]

Nope, I think Wendell has it right - three-point hitches usually don't have the ability to impart down force. The implements do it, usually by sheer mass or, in the case of plows, by down-vector forces imparted by the shape of the blade(s). If you have some accessory implement, like a three-point-hitch-mounted backhoe, that's a whole 'nother story...
