Hot on the heels of its flagship twin-rotor CR11 combine launch, New Holland has introduced a lower-powered CR10.

Specs are almost identical to that of its bigger sibling, apart from the fact that it has a lower-capacity 16,000-litre grain tank and a smaller 12.9-litre FPT six-cylinder engine that develops 635hp.

In comparison, the CR11 can hold 20,000 litres of grain and its 15.9-litre engine – also a six-cylinder – is good for 775hp.

Key features on both models include the option of 10.6 to 15m (30 to 50ft) headers and 600mm rotors to do the threshing and separating.

These are longer and larger in diameter than those used on the firm’s CR10.90, which the CR10 will supersede.

Cages surrounding these are also updated, with a broader, stepped design that has higher vanes in the separation area.

The idea being that this provides more effective crop movement, improves separation and reduces the load put on the engine.

The cleaning shoe has been designed to boost throughput and minimise losses, with a neat system for evening out crop distribution.

This uses pressure sensors on the grain pan and upper sieve to monitor the distribution of the crop, before signalling a shaking mechanism to level any lumps.

Residue management has also been addressed, with option of either a standard integrated chopper or a high hood-mounted fine-chop unit.

Both the CR10 and CR11 will be demoed this harvest, with deliveries of production-spec machines scheduled for 2025.
