The innovative technology of New Holland's CR Revolution

the combine segment, one of New Holland's flagships is undoubtedly the CR Revelation range. This is a line of machines that, as the manufacturer itself points out, has been designed with the aim of offering a high harvesting capacity (+10% according to the Modenese company) while improving grain quality and residue management.

A great strength of the CR Revelation models is the innovative rotor design (TwinPitch type with 3" shelling elements). The crop flow is remotely adjustable directly from the cab via inclined flaps - the position can be infinitesimally varied between slow and fast - which not only rationalises fuel consumption but also optimises the grain flow. The concave reset function helps to increase the combine's productivity and considerably reduce downtime in the event of an overload on one of the concaves.

To reset them, the operator only has to stop the combine's forward motion, have the rotors unloaded and engage the automatic reactivation function.

Compared to the manual procedure, the solution adopted by New Holland allows a gain of 20 to 30 minutes.

The residue management system is also innovative, designed for finer chopping of the crop, wider spreading and better distribution.

The implementation of the straw chopper with a reinforced rotor, with larger counter-blades and an even higher operating speed, allows for finer chopping, as well as a 50% reduction in long straw.

The straw spreader, on the other hand, has been equipped with a pneumatic product flow system that has replaced the traditional impact model and has allowed the spreading width to be increased to 45 feet (13.7 m). Another plus of these machines is the straw management system, called Opti-Spread, which features more vigorous hydraulic motors (+25%), 'V' shaped vanes and cleaning scrapers.

This has enabled the manufacturer to extend the spreading profile, optimising it while reducing component wear. Important technological content is offered by the IntelliSense system for the automatic management of machine functions.

With IntelliSense - reads a New Holland technical note - the sensors in the sieve box provide very precise measurements of the sieve load. Based on this data, the combine constantly adjusts the vane angle and speed of the Twin Pitch rotors, the speed of the OptiFan™ and the opening of the pre-sieve, top and bottom sieves to achieve the desired result.

Adjusting the rotor vanes improves rotor energy efficiency without affecting threshing and separation settings, and produces higher yields with reduced fuel consumption. Four operating modes can be selected by the operator: limited loss, grain quality, maximum productivity, fixed yield. On the other hand, the crop feeding system, called IntelliCruise, automatically adapts the forward speed to the load with a choice of three different harvesting options.

The 'maximum productivity' mode increases the combine's forward speed using maximum engine power or maximum forward speed; the 'fixed yield' mode changes the forward speed to maintain the pre-set crop flow and achieve constant productivity as yields vary; the 'limited loss' mode changes the forward speed to maintain the defined crop flow (if losses exceed 50% of the pre-set value, the flow is reduced to limit them).

Three control configurations of the IntelliCruise system are therefore available: maximum motor load, maximum feed speed and feed speed sensitivity, which allows the operator to define the system's responsiveness.
