Grain Auger or Belt Conveyor? Matching Capacity, Reach, and Crop
Share
Truck-to-bin capacity is a system number, not just the rating on the auger or conveyor. The machine still has to reach the bin, fit under the trailer, match the available power, and handle the crop the way the operation requires.
A 10,000-bushel-per-hour rating does not settle the comparison. A longer swing-away auger may provide the reach for a tall bin. A belt conveyor may fit seed, specialty crops, frequent cleanout, or a site where gas or electric power makes more sense than keeping a tractor on the auger.
Start with the whole receiving system
If a trailer holds 1,000 bushels and the target unload time is eight minutes, the grain-handling equipment must average 7,500 bushels per hour for that load.
The rest of the bin site must keep pace. An auger or conveyor rated above 10,000 bushels per hour will not shorten the stop if the leg, dryer, bin inlet, or other receiving equipment can accept only 6,000. The limiting rate may be downstream from the machine beside the truck.
Published capacities also depend on the crop, moisture, intake, drive, and working angle. Use the rated capacity to narrow the field, then confirm the figure for the length, drive, and working position being quoted.
These numbers make the first comparison useful:
- trailer capacity and target unload time;
- rated capacity of the downstream equipment;
- crop and expected moisture range;
- required discharge height and horizontal reach;
- clearance under the trailer;
- available PTO, hydraulic, gas, or electric power; and
- how often the machine will move or change crops.
Where a swing-away auger fits
A swing-away auger remains a strong choice for high-capacity truck-to-bin work. Its hopper reaches under the trailer while the main auger is positioned at the bin. Manufacturers offer a broad range of tube diameters, lengths, lift systems, hopper movers, and controls.
A swing-away auger fits the job when:
- the main work is moving commodity grain into storage;
- a suitable PTO tractor is available;
- the bin requires the reach and discharge height of a longer auger; and
- the complete auger package meets the capacity target at an acceptable cost.
Price the machine as it will work on your farm. A hopper mover, winch, lighting, controls, lift package, and larger PTO requirement can change both the cost and the tractor match.
Brandt's current swing-away families show the capacity range available in augers. Brandt rates its 10-inch HP models at 7,200 bushels per hour, the 13-inch XL+ at 11,000, the 13-inch HP+ at 13,000, and the 16-inch HP at 23,000. Length and capacity are separate specifications: extra length adds reach, not automatically more bushels per hour.
Where a field belt fits
A portable belt conveyor, or field belt, carries grain on a belt rather than through auger flighting. It earns a closer look when gentle handling, lower power demand, or cleanout between crops matters more than maximum auger capacity.
AGI Batco builds belt conveyors for grain, seed, and specialty crops. The current 1500 Series is rated up to 6,000 bushels per hour, and the 2000 Series is rated up to 9,000. Capacity increases as the operating angle decreases, so the rate at the required discharge height matters more than the highest figure in the brochure.
A belt conveyor can be a better fit when:
- seed or another damage-sensitive crop is part of the work;
- several crops will pass through the same machine;
- available horsepower is limited;
- gas or electric drive fits the bin site better than PTO power; or
- the machine will cover truck loading and other transfer work during the year.
The belt still has to meet the required capacity, rise, reach, intake clearance, and transport needs. A conveyor that works well as a field loader may not reach a tall bin, and a long conveyor without the correct drive and lift package is not a complete quote.
Reach and working angle can rule out a machine
Two machines with the same overall length can place the discharge at different heights and distances. Frame design, hopper position, lift, and working angle all affect where the discharge sits.
Measure the receiving height, the horizontal space available, clearance under the trailer, and any width or height limits around the bin site. Compare those measurements with the manufacturer's height-and-reach chart for the exact model.
The useful question is not simply how long the machine is. It is whether that length will reach the inlet at a workable angle while the hopper remains where the truck can unload.
Account for every power function
“Electric” may describe only the hopper mover or winch while the main auger still runs from the tractor PTO. Belt conveyors may be offered with gas, electric, hydraulic, or PTO drive, but the choices vary by model and length.
Separate each power requirement on the quote:
| Item | What to confirm |
|---|---|
| Main drive | Tractor PTO, electric motor, gas engine, or hydraulic drive |
| Hopper or intake drive | Whether it uses the same power source as the main machine |
| Lift, winch, and mover | How each function is powered and controlled |
| Tractor requirement | Horsepower, PTO speed, hydraulic flow, pressure, and remotes |
| Electrical service | Voltage, phase, amperage, cord, and connection at the bin site |
Include tractor time in this comparison. If a tractor stays on a PTO auger, that tractor and operator are not available for another job. If electric drive is being considered, the required service must be available where the conveyor will actually run.

| Main drive and power requirement | ||
| Hopper, mover, winch, and lift equipment | ||
| Transport width, height, and storage space | ||
| Crops and frequency of cleanout | ||

One machine may not need to replace the other. Some farms use a swing-away auger for the main bin-filling work and a shorter belt conveyor for seed, truck loading, or transfers where gentle handling and cleanout matter more.
Auger or belt: the practical difference
A swing-away auger is often the direct, high-capacity choice for moving commodity grain from a truck into a bin. A belt conveyor gains ground when crop quality, cleanout, power flexibility, or several transfer jobs matter more.
