Integration of High-Capacity Harvesting Systems in Seed Production

Fairfield Farms has concluded field evaluations of the New Holland CR11 next-generation combine, leading to a planned fleet transition in 2026. The cooperation focused on assessing the machine’s throughput and reliability within the complex digital infrastructure of modern industrial farming, specifically targeting high-value seed crops in challenging climatic conditions.

Technical Challenge and Operational Context
Large-scale arable operations, such as Fairfield Farms’ 2,200-hectare production area in Canterbury, require high machine availability during narrow harvest windows. The technical challenge involves maintaining low grain loss and sample purity while processing heavy, windrowed crops like grass, brassica, and clover seeds.

The cooperation between the grower, the manufacturer (New Holland), and the regional integrator (Cochranes) was established to test the CR11’s Twin Rotor technology against traditional mechanical limitations. In the 2025 harvest, high moisture levels necessitated a system capable of operating in marginal conditions where conventional belt-driven machines faced torque limitations.

System Architecture and Drivetrain Efficiency
The CR11 introduces a revised architectural approach to power transmission. By replacing several traditional belts and pulleys with a direct-drive system, the machine reduces parasitic power loss. This configuration ensures that maximum engine torque is delivered directly to the threshing and separation components, which is critical for processing dense, high-volume pickup crops.

During technical trials, the following performance ratios were recorded compared to the previous CR10.90 standard:

These metrics allow two CR11 units to replace the operational output of three standard high-capacity machines, streamlining logistics and reducing the required operator count.

Implementation and Small-Seed Validation
Cochranes managed the deployment of the CR11 at Fairfield Farms to gather real-world data on perennial ryegrass and other hybrids. These trials served as a global benchmark for small-seed harvesting, as the Canterbury Plains represent one of the highest-density seed production zones globally.

The implementation focused on the machine’s ability to handle large pickup fronts. The CR11’s increased internal width and processing speed allowed for the simultaneous lifting of two windrows at standard harvesting speeds. This capability, combined with the simplified maintenance profile of the direct-drive system, improves overall process stability.

Impact on Industrial Agriculture
The transition to this high-capacity platform addresses the requirement for increased efficiency in industrial automation and harvesting logistics. By extending the operational window by 30 to 60 minutes in marginal weather, the system mitigates the risk of crop degradation. For professional growers, the deployment signifies a shift toward simplified mechanical designs that prioritize uptime and quantifiable throughput in high-value seed sectors.
