Harvest uptime
when windows
are tight.
The Raptor is a stripper header engineered for the hours that matter most. When a breakdown costs thousands and the weather won't wait, you need a header built around serviceability, parts access, and consistent high-speed performance — not just capacity.
Why operators switch to the Raptor
Five areas where the Raptor was engineered differently from headers that prioritize capacity over reliability.
Better balance. Cooler operation.
Headers with unbalanced rotor assemblies create vibration, stress, and heat at the combine connection — leading to premature wear, fatigue, and downtime when the header should be running.
The Raptor's rotor assembly is balanced for smoother operation and reduced heat at the combine header mount. Less vibration means less wear on the combine, less fatigue on the operator, and more hours between interruptions. The balanced design also contributes to cooler operation during high-speed harvesting, reducing the thermal load that contributes to premature component failure.
- Balanced rotor assembly for reduced vibration
- Cooler operation at the combine connection
- Reduced wear on combine components
- Less operator fatigue during long harvest days
Simplified maintenance. Faster repairs.
When a header needs service in the middle of harvest, most designs require the machine to be pulled apart, special tools, and hours of downtime while the crop sits in the field.
The Raptor is designed around serviceability. Components are laid out for access, not tucked away where they can't be reached. Wear parts are positioned where they can be inspected and replaced without major disassembly. The stainless steel keyhole fingers are designed for durability and straightforward replacement when the season eventually demands it.
Faster repairs in the field mean fewer hours lost during tight harvest windows. A header that's easy to service is a header that keeps you moving when the weather window is closing.

- Stainless steel keyhole fingers for durability
- Reduced disassembly for routine service
- Designed for real-world repair conditions
Low grain loss. High throughput.
Many headers sacrifice grain loss for speed. Push the RPM and the losses climb. Slow down to protect yield and the acres per hour drop. The trade-off feels unavoidable.
The Raptor's variable rotor speed (400-800 RPM) lets operators dial in the right performance for the crop condition — not a fixed speed that works in some conditions and wastes grain in others. The stainless steel keyhole fingers are designed to maintain consistent threshing and stripping quality across varying crop densities and moisture levels. The result is the ability to maintain higher ground speeds without the grain losses that show up on the yield monitor at the end of the day.
- Variable rotor speed: 400-800 RPM
- Stainless steel keyhole fingers
- Consistent performance across crop conditions
- Higher speed without increased grain loss
Minimal straw breakup. Better residue.
Aggressive threshing and high-speed rotor action pulverize straw into fragments that don't protect the soil surface, don't hold moisture, and create challenges for the next seeding pass.
The Raptor's rotor and finger design is tuned for stripping — not pulverizing. The stainless steel keyhole fingers work the crop head with minimal straw breakup, leaving intact residue that covers the soil, preserves moisture, and sets up the next season's seeding conditions. For operators who think in systems across multiple seasons, the quality of the residue left behind matters as much as the grain in the tank.
Intact residue means better moisture retention, less soil erosion, and cleaner conditions for low-disturbance seeding. The residue the Raptor leaves behind helps next year's crop from the day this year's harvest is finished.
- Stripping action designed for minimal straw breakup
- Intact residue for soil coverage and moisture retention
- Sets up better conditions for next-season seeding
- System-level thinking across multiple seasons
Parts access. Support that knows harvest.
When a header component fails during harvest, the difference between a quick fix and a season-derailing delay is often parts availability. Some headers require parts from overseas or proprietary systems that can't be sourced quickly.
The Raptor is designed and supported by K-Hart — an independent manufacturer in Manitoba with a dealer network across Western Canada and the Northern Plains. Parts are available through the same dealer network that supports the Spyder disc drill. The design philosophy prioritizes common, replaceable components over proprietary systems that create dependency. When a part is needed, it's available. When support is needed, the dealer knows the machine and the harvest conditions you're running in.

- Common, replaceable components — not proprietary systems
- Parts available through the same network as the Spyder

Performance
Built for high-speed harvesting with consistent results across varying conditions.
Speed that matches the crop, not the spec sheet.
The Raptor's variable rotor speed (400-800 RPM) gives operators the control to adjust for crop density, moisture, and field conditions on the fly. A fixed-speed rotor is optimized for one condition. The Raptor is optimized for the real conditions you face during harvest — which change from field to field and hour to hour.
The stainless steel keyhole fingers maintain consistent stripping quality across the full RPM range, so the performance doesn't fall off when the speed goes up. The result is the ability to maintain ground speed without the grain losses that cost yield at the end of the season.
Variable Rotor Speed
400-800 RPM range for dialing in performance across crop density, moisture, and field conditions.
Stainless Steel Fingers
Keyhole fingers designed for durability and consistent stripping quality across the full RPM range.
Low Grain Loss
Maintain higher ground speeds without the grain losses that show up on the yield monitor.
Minimal Straw Breakup
Intact residue preserves soil moisture and sets up better conditions for next-season seeding.
Design
Engineered for serviceability, balance, and compatibility with the combines you already run.
Engineered for the hours that matter most.
The Raptor's balanced rotor assembly is designed to reduce vibration and heat at the combine connection — two of the biggest causes of premature wear and unplanned downtime during harvest. The balanced design contributes to smoother operation, less operator fatigue, and more consistent performance across long harvest days.
The header's serviceability is built into the architecture, not added as an afterthought. Wear parts are positioned for access. Components are designed for straightforward replacement. The stainless steel keyhole fingers are engineered for durability and easy service when the time comes.
A header that runs cooler, vibrates less, and can be serviced quickly is a header that keeps you in the field when the crop is ready and the weather is closing in.
