OVERVIEW

The Demco Steel Hopper-Bottom Grain Trailer is engineered for professional grain harvesters who demand durability, visibility, and consistent performance in real-world field conditions. Designed by and for working grain operators, this trailer is built to handle daily hauling tasks in changing weather, heavy loads, and long transport distances.

Constructed with heavy-gauge steel and reinforced structural components, Demco steel hopper-bottom trailers are designed to minimize frame twisting, improve towing stability, and deliver reliable performance throughout the harvest season. Standard 66-inch sidewalls provide a clear view into the hopper from the combine cab, allowing operators to monitor grain levels efficiently while loading.

A vertical rib wall design helps reduce air drag during transport and minimizes rock chipping, contributing to improved fuel efficiency and a cleaner exterior over time. With multiple available lengths and hopper configurations, the Demco Steel Hopper-Bottom Grain Trailer can be configured to meet the capacity, axle, and clearance requirements of different grain hauling operations.

Built for agricultural transport, farm operations, and commercial grain hauling, this trailer delivers the strength, usability, and long-term reliability Demco is known for.
