On a farm, belts work in short, intense bursts. A combine may stand idle for months and then run from dawn to late night through the harvest, in dust, chaff and 40 °C sun. A thresher belt that snaps on the busiest day of the season stops everything. Good belts, stored and fitted properly, make that much less likely.
Use belts made for the machine's drive: agricultural (harvester) belts and hexagonal belts where the maker specifies them, and classical A, B or C belts for threshers, chaff cutters and pumps. Before every season, inspect and replace cracked belts, clean and gauge pulleys, align and tension the drives, and keep a set of spares with the codes noted.
| Machine | Usual belt type | Notes |
|---|---|---|
| Combine harvesters | Harvester (agricultural) belts, hexagonal belts, wedge belts | Follow the maker's part codes exactly |
| Tractor-driven threshers | Classical B or C | Heavy shock loads; check alignment with tractor PTO set-ups |
| Chaff cutters | Classical A or B | Keep guards fitted; clean chaff from grooves |
| Reapers and small harvesters | Classical or agricultural belts | Often run on small pulleys |
| Farm pumps and borewell drives | Classical B or C | Long running hours; watch tension |
| Flour mills, oil expellers, rice hullers | Classical B, C or D | Continuous running; matched sets on multi-belt drives |
Hexagonal belts carry power on both faces, which makes them suitable for the serpentine drives found on some harvesters. Agricultural belts are built for flexibility and the side loads of farm drives. We compare profiles in classical vs wedge vs cogged V-belts.
Many agricultural belts look alike but differ in length, section and construction. Order by the code printed on the belt or listed in the machine's parts book. If the code has worn off, follow how to measure a V-belt or send the old belt's measurements.
Harvest demand arrives all at once. Dealers who stock the fast-moving belt codes for the combines and threshers in their area before the season, and keep matched sets for multi-belt drives, win the repeat customers. Banesto makes Beltone classical, hexagonal and harvester combine belts; talk to our team about the codes your market needs.
Which V-belt is used in a thresher?Most tractor-driven threshers use classical B or C section belts. Check the machine's parts book or the code on the old belt.
What is a hexagonal V-belt used for in agriculture?Drives where pulleys sit on both sides of the belt, as on some combine harvesters, so power is transmitted from both faces.
How should V-belts be stored in the off-season?In a cool, dark, dry place, hung on wide pegs, away from sunlight, engines and chemicals. Release tension on idle machines where allowed.
Why do harvester belts fail during the season?Common causes are dust and chaff in the grooves, shock loads, worn pulleys, misalignment and wrong tension, often after belts aged during the off-season.
