Weight Restrictions on Public Roadways for Tank Wagons


By Mark Hanna, Extension Ag Engineer, Department of Agricultural and Biosystems Engineering

TankwagonLegislation passed in 2000 established axle weight restrictions on public roadways for tank wagons hauling manure, grain carts with non-steerable axles and fence-line feeder wagons. Beginning July 1, 2005 these implements are restricted to a maximum gross vehicle weight of 96,000 pounds (not including weight of the farm tractor). Maximum weight of any single axle is limited to 24,000 pounds from February through May or 28,000 pounds the rest of the year. In addition to weight restriction on these implements, all agricultural vehicles (including tractors, combines and implements) are required to comply with weight embargoes posted for bridges and culverts.
