Don't leave your profits in the dirt this season. Every bushel saved at the header is pure profit in the bin. Upgrade your combine header with Raptor Draper Belts today and experience smoother feeding, less maintenance, and maximum yield recovery.
Raptor® Draper Belting—originally developed by WCCO Belting and now part of Continental—increases field yields by directly targeting shatter loss, crop flow mechanics, and machine uptime.
While a standard belt simply moves material, Raptor belting uses advanced material science to fundamentally alter how gently and consistently a crop is handled from the cutter bar to the feeder house.
1. Controlling "Shatter Loss" with the Edge Defender®
Shatter loss occurs when mature, brittle seed heads (like wheat or soybeans) slam violently into standard header components, shelling grain before it ever reaches the threshing drum.
- The Problem: Traditional straight cleats allow pods and seed heads to roll sideways or backward, often getting pinched or trapped against the rigid metal cutter bar, where they are crushed.
- The Raptor Solution: Raptor belts utilize a patented Edge Defender® angled cleat design. These unique, sculpted cleats act as a directional guide. They actively funnel and sweep loose grain away from the abrasive cutter bar and immediately keep it toward the center of the belt canvas. This keeps the most fragile pods moving gently inward rather than dropping to the soil.
2. Eliminating Crop "Bunching" & Slugging
A combine harvester's threshing and cleaning shoes operate at peak efficiency only when they receive a smooth, uniform mat of material.
- The Problem: Lower-grade belts slip under heavy loads. This causes the crop to temporarily pile up on the sides of the header. When the belt finally catches, it forces a massive "slug" of tangled material into the feeder house all at once. This causes a sudden RPM drop, poor grain-to-chaff separation, and significant grain being blown right out the back of the combine.
- The Raptor Solution: Raptor draper belts are engineered with a specialized filament fabric weave that resists stretching and pulling under maximum load. By eliminating belt lag, the crop feeds into the combine as a highly consistent, uniform mat. The internal threshing mechanism stays perfectly loaded, optimizing separation and heavily dropping your tail-loss percentage.
3. Structural Mechanics: Stiffness and Tracking
How a belt behaves structurally on its rollers dictates how much grain escapes through the header's gaps.
- Teardrop Fiber Reinforcement: Raptor belts incorporate an innovative, teardrop-shaped fiberglass rod vulcanized directly inside the center of each cleat. This gives the belt immense cross-directional rigidity, preventing the edges from curling up or folding down under heavy, wet crop weights.
- Zero-Gap Tracking: By pairing a stiff fabric base with precise, molded V-guides on the underside, the belt tracks flawlessly straight on its rollers without walking. Flawless tracking means the gap between the belt edge and the header seals remains completely closed, entirely blocking small grains like wheat or canola from slipping beneath the machine.
4. Compounding Your Yield: Starting Earlier, Stopping Later
Yield isn't just measured in bushels per acre; it's measured in capturing the maximum crop volume during the absolute best weather window.
- Friction vs. Skim Coatings: Raptor features a highly specialized dual-rubber design—a durable skim coat on top to fight stubble abrasion, and a low-friction coat on the bottom. This reduces mechanical drag and hydraulic pressure requirements.
- Field Reliance: Because the belt pulls smoothly without bogging down the combine's hydraulics, harvesters can head into the field earlier in the morning when dew is still on the plant, and cut later into the damp evening without worrying about the belt stalling out or plugging. Expanding your operating window means harvesting more of your crop at its peak nutritional value.
