According to today's USDA Grain Transportation Report, the Iowa governor has extended through February 19 the harvest-time proclamation that suspends weight limits for vehicles transporting grain, fertilizer, and manure.
The harvest proclamation allows vehicles to be overweight without a permit (not exceeding 90,000 pounds gross weight) when they are transporting corn, soybeans, hay, straw, silage, stover, fertilizer (dry, liquid, and gas), and manure (dry and liquid).
