Refers to the debate over the benefits and drawbacks of using engine-powered vehicles instead of livestock to pull processing-implements for crop-fields. A protractor is a geometry device used to create/plot charts and graphs showing the various advantages that gas/diesel/electric motive-power has over horses or oxen, while a contractor is a hired professional whose job is to present the negative effects of motorized farm-machinery.
The whole protractor vs. contractor issue is not one that has an easy answer or solution --- on the one hand, modern farm-machinery is easier and simpler to operate, but horses and oxen do not cost nearly so much to purchase or maintain.
