Report Objective

Evaluate Razors Edge Concaves against the John Deere OEM concaves in green mung beans, measuring grain-loss reduction, mechanical damage, fuel savings, operational performance, and the resulting financial impact.

Evaluation Methodology

Loss was verified physically using the ScherGain Drop Pan System. Samples were collected over 0.5 m² areas, converted to kg/ha and per-hectare losses, and averaged across multiple drops for each concave set. Both sets were run back-to-back in the same field and conditions.

Technical Results

MetricOEM ConcavesRazors Edge
Area evaluated93.9 ac64.25 ac
Average loss1.21 bu/ac0.11 bu/ac
Average fuel6.74 gal/ac5.89 gal/ac
Average speed3.4 km/h4.4 km/h
1.10 bu/ac less loss

Loss dropped from 1.21 to 0.11 bu/ac — about 1,508 bushels recovered across the area, worth $22,621.50 at $15/bu in the mung-bean area alone.

Economic Impact

  • Loss recovery — 1.10 bu/ac improvement × area = ~1,508 bu recovered = $22,621.50 (at $15/bu).
  • Fuel savings — 0.85 gal/ac less (6.74 → 5.89) = ~1,166 gal saved = $1,200.66 (at $1.309/gal).
  • Throughput — +1 km/h harvest speed with lower engine load, without sacrificing sample quality.

Operational Efficiency

The evaluation noted a significant reduction in the engine load required, which let the operator increase harvest speed from 3.4 to 4.4 km/h while maintaining clean sample quality — more acres per day from the same machine.

Test conditions

Start 11:00 am · cloudy, 91°F · crop moisture above 19% · ~4-hour run · spreaders off for sampling.

Conclusion

Razors Edge Concaves delivered relevant technical and economic gains over the OEM alternative — averaging 1.10 bu/ac less loss (from 1.21 to 0.11 bu/ac), representing $22,621.50 in the mung-bean area alone, alongside fuel savings and increased operating speed. The product is technically proven and economically viable for this operation.
