Corn Growers Announce 60 Day Harvest Weight Limit Waiver

September 25, 2015

To help haul in this year’s harvest, Governor Terry Branstad signed into effect today a proclamation granting a temporary weight limit exemption for trucks on Iowa roads. The proclamation specifically increases the weight allowable for shipment of corn, soybeans, hay, straw and stover, by 12.5 percent per axle (up to a maximum of 90,000 pounds) without the need for an oversize/overweight permit.

The 2015 proclamation again applies to loads transported on all highways within Iowa, excluding the interstate system. Trucks cannot exceed the truck’s regular maximum by more than 12.5 percent per axle and must obey the posted limits on all roads and bridges.

“We as farmers understand the harvest weight proclamation is not a right by law, but a petition to the Governor,” said Bob Hemesath, a farmer from Decorah and President of the Iowa Corn Growers Association (ICGA). “On behalf of Iowa farmers, we sincerely thank Governor Branstad for the proclamation, which will significantly improve farmers’ efficiency during harvest.”

ICGA provided Governor Branstad the information required for a proclamation, as well as information on the estimated harvest predictions. The proclamation directs the Iowa Department of Transportation to monitor the operation of the proclamation, assure the public’s safety and facilitate the movement of the trucks involved. Farmers who are transporting grain are also required to follow their vehicle safety standards on axle weights.

The exemption will be granted for 60 days beginning, September 25, 2015.


The Iowa Corn Growers Association (ICGA) is a membership organization lobbying on agricultural issues on behalf of its 8,000 farmer members.
