The laws are designed to ensure safety on the roads for farm machines as well as other vehicles. Byrnes reviews some basic information in Minnesota's laws regarding implements of husbandry. License plates and vehicle registration are not required for implements of husbandry. However, a truck towing an implement must have a license plate. A farm trailer with a gross weight of 10,000 pounds or more pulled by a car, pickup or truck must have a registration plate.
Surge brakes capable of holding, stopping and controlling a vehicle are acceptable.
The emblem must be visible 600 feet from the rear of the vehicle. Towed implements that obscure the towing vehicle's SMV must have an emblem of their own. Chains, ropes or cables used for towing farm implements must be marked with a flag. Other lights are required from sunset to sunrise, during rain or anytime visibility is impaired. Self-propelled implements must have two amber flashing hazard lights visible to the front and rear, one white light headlight visible to the front, one rear taillight visible to the rear, and two red reflectors visible to the rear.
