ken3q,
How much actual experience do you have with moldboard plows?

The reason I ask is your "time saving" comment. Is it better to spend 15 minutes cleaning up the moldboard before one begins, or get off the tractor every five minutes for the first half hour to scrape accumulated soil off?

Also, although there are many extremely dangerous jobs on the farm, plowing, unless one falls off of the tractor, is notamong them.

Although I use moldboard plows less and less as the years have worn on, and there are untold numbers of things I don't know much about, moldboard plows/plowing is not one of them.
