Harvest season doesn’t wait. When a combine belt fails in the middle of a wheat field, every hour of downtime costs money — not just in repair costs, but in crop losses if the weather turns. We’ve heard the stories from our agricultural customers: a $30 belt failure that turned into a $10,000 problem because the replacement took three days to arrive.
That’s why we stock common harvester belt sizes and maintain relationships with agricultural distributors who understand that “next week” isn’t an acceptable delivery time during harvest. We’ve been manufacturing agricultural belts since 2005, and we’ve learned that this market has zero tolerance for quality compromises.

A modern combine harvester uses dozens of belts to drive various systems. Here’s where our belts go:
We manufacture replacement belts for all major combine harvester brands:
S-Series (S760, S770, S780, S790), T-Series, W-Series, and older 9000/9500/9600 series. We maintain cross-reference data for John Deere part numbers.
Axial-Flow series (7250, 8250, 9250), legacy 2388/2588 series. Cross-reference available for Case IH and legacy International Harvester part numbers.
CR series, CX series, TC series. Compatible with New Holland and legacy Ford/Versatile equipment.
Lexion series, Tucano series, Dominator series. European specifications available.

Agricultural equipment operates in conditions that would destroy standard industrial belts:
Combines operate in clouds of chaff, dust, and crop residue. Belt surfaces must resist abrasion from particulate contamination. Our agricultural belts use compounds formulated for abrasion resistance, not just power transmission.
Harvest happens in summer heat — ambient temperatures of 35-40°C are common, and belt operating temperatures can exceed 80°C. Our EPDM compounds handle these conditions without degradation.
Crop flow isn’t constant. A slug of heavy material hitting the threshing system creates instantaneous torque spikes. Our belts use Aramid cord reinforcement for heavy-duty applications to handle shock loads without stretching or breaking.
During harvest, combines run 12-16 hours per day for weeks. There’s no time for belt changes mid-season. Our belts are designed for the full harvest season without replacement.
Our standard compound for agricultural V-belts. Natural rubber offers excellent elasticity, tear resistance, and fatigue life — critical for the constant flexing and shock loading in harvester applications.
For applications with high heat exposure or where longer service life justifies the cost premium. Recommended for engine-driven accessories and high-speed drives.
Heavy-duty applications (cylinder drive, main separator drives) benefit from Aramid (Kevlar) cord reinforcement. Higher tensile strength and lower stretch than polyester.
Agricultural belt failures during harvest are catastrophic. Our IATF 16949 certified quality system ensures:
We work with agricultural equipment dealers and parts distributors on supply programs:
Beyond combine harvesters, we manufacture belts for:
Best method: Find the OEM part number in your operator’s manual or on the old belt. Send us the part number, and we’ll identify the correct replacement. If you don’t have the part number, send us the equipment model and which drive system needs the belt.
For critical drives (cylinder, separator, feeder), we recommend replacing belts as a set if they’re the same age. A belt that’s been running for several seasons is likely to fail soon after its partner is replaced. For less critical drives, individual replacement is usually fine.
Common sizes: 5-7 business days (we stock popular specifications). Less common sizes: 15-20 business days. During pre-harvest season (April-June for Northern Hemisphere), we recommend ordering 6-8 weeks ahead.
Standard agricultural belt sizes: 300 pieces. Custom specifications: 500 pieces. For distributors building pre-season inventory, we offer flexible terms. Contact us to discuss.
Yes. We understand that harvest-season failures require immediate response. Air freight is available for urgent orders. Contact us directly for expedited options.
