About Harvest Equipment
Harvesting a crop is one thing. Getting the crop out of the field is another. That’s where the machines in the Harvest Equipment category come in. These machines are organised into four subcategories, including chaser bins, gravity wagons, silage wagons, and other harvest equipment (boll buggies, defoliators, etc.). Whether transporting alfalfa, corn, cotton, soybeans, or grain, harvest equipment allows for the temporary storage and hauling of several hundred to a thousand or more bushels of crop to a final destination, such as a grain bin on the farm, a local grain elevator, or a feedlot.

Common Features
Although they serve a function as old as farming itself, machines in the harvest equipment category often come loaded with new and innovative features. Grain carts, for example, are now available in both wheel and track models; tracks provide better flotation, especially in soft soil conditions, and cause less compaction. You’ll also find harvest equipment decked out with sensors, cameras, monitors, and other advanced features that make them safer to operate and easier to load and unload.
Chaser Bins
Chaser bins, also referred to as “grain carts” or "grain auger wagons," are tractor-pulled machines that travel alongside or behind harvesters so combines or forage harvesters can offload their payload without stopping or leaving the field. They often then transport harvested crop to a waiting grain truck and use an auger system to unload the grain. They can include such features as directional downspouts, electric tarp systems, front-located augers that provide enhanced visibility, hydraulic doors, integrated weighing systems, dual augers, and remote downspout control.
Gravity Wagons
Gravity wagons, on the other hand, use gravity and their sloped side walls in concert with side- and bottom-located doors to offload material quickly, which is why you’ll sometimes see them referred to as “slant” or “gravity flow” wagons. Some models also feature specially coated interiors for faster unloading. Unlike grain carts that typically remain in the field, gravity wagons generally transport the crop to where it will permanently be stored. In addition to access ladders and viewing windows, grain wagons may include small doors for drawing crop samples, side extensions to increase capacity, dual interior compartments, centre dump chutes for pit unloading, and tarp covers.
Silage Wagons
Silage wagons are sometimes called "forage boxes" or "forage wagons." They typically offer front or rear unloading (or both) and can either be attached to a forage harvester or be pulled behind or next to one. Beaters or augers and a floor apron help move the crop. You'll find self-contained wagons, truck-mounted boxes, and semi-trailer options on the market. There are even specialized forage wagons with integrated trap doors and a windrow pickup mechanism that can grab, cut, and transfer the crop into the wagon.
