New Holland improves productivity with Agritechnica award winners  

New Holland has once again proven its reputation for technical ingenuity with three awards, one Gold and two Silver, presented to the company by the judges at the next Agritechnica machinery show. The awards, which recognise technical innovation with practical benefits on production, have been bestowed on the FR9000 forage harvester’s IntelliFill™ system, the CSX7000 combine’s Opti-Fan™ system and the ABS SuperSteer™ for the T7000 series tractors.

Automatic Trailer Tracking gets Gold 

Receiving a Gold medal, Agritechnica’s highest award, the FR9000’s IntelliFill™ system allows the operator to fill a trailer accurately and with minimal losses, even when visibility is limited. Following a front-to-rear or rear-to-front pattern, the automatic trailer tracking system uses a specialised 3D camera mounted under the spout to guide the crop flow into the trailer. The system ensures a uniform fill whether the trailer is alongside the forage harvester, or following, in the case of starting new fields. The system can accurately control the crop flow trajectory even when operating at night.

The spout-mounted sensor creates a distance image of the trailer and its surroundings, based on NIR (near infra red) technology. Unlike conventional mono or stereo camera systems, which have poor depth perception, the New Holland tracking system can accurately position the crop flow to a distance of 20 metres.

The system can operate in conjunction with any trailer without need to calibrate or adjust to recognise any new trailer. This allows the operator to automatically control the position of the spout and to consistently fill any type of trailer.

The driver benefits from improved operating comfort and safety and is able to concentrate on the front of the machine and increasing work rate. During long working days, and even in the dark, the automatic spout guidance will consistently reduce spoilage of crop, thus increasing the overall quality of work of the forage harvester.

Opti-Fan™ system takes Silver 

New Holland’s CSX7000 combine offers large combine capacity in a more compact combine frame. Advanced features, such as SmartSieve, enable the CSX7000 to maintain high productivity levels with low grain loss when working across slopes. Sensors monitor the inclination of the combine and adjust the throw of sieves to ensure that crop flows evenly through the combine and does not gather on the down-slope side.

The silver-medal winning Opti-Fan™ system takes combine performance on slopes to the next stage, with automatic compensation for continuous uphill or downhill gradients.

When driving downhill, material moves against gravity and therefore more slowly over the grainpan and top sieve, causing it to remain longer in the cleaning shoe and the layer thickness to increase. More ‘material other than grain' (MOG) remains in the cleaning shoe as the set cleaning fan speed is insufficient to clear the crop. Driving uphill causes the material layer to decrease as it moves more quickly out of the shoe under gravity. The air flow from the fan is too high for the thin layer of material which results in the material travelling too quickly over the top causing increased grain losses.

The fan speed control system senses the combine’s angle of ascent or descent and automatically adjusts the cleaning fan speed to compensate. The operator sets the level-field fan speed and the system reduces the speed when travelling uphill and increases it downhill to optimise the material layer thickness on the cleaning shoe. No extra work is required from the driver and losses are reduced and the grain sample is improved. 

Silver medal for ABS SuperSteer™

Anti-lock braking systems for cars and lorries are now commonplace. But the added complications of heavy mounted articulated equipments, uneven terrain and a huge amount of variation in traction conditions, even from wheel to wheel, means that an effective antilock braking system for tractors requires more advanced development. New Holland has won a silver award for its ABS SuperSteer™ - a smart application of ABS technology to tractors, which not only offers confident stopping power with increased safety, but also increases tractor manoeuvrability and improves safety when operating on steep hills.

ABS SuperSteer™ uses ABS technology to manage each wheel’s brake individually. This new feature will be available on current and future New Holland high power, high speed tractors like the T7000 Auto Command. ABS SuperSteer™ will enable a new generation of 60kph-capable, front-axle suspension tractors achieve an outstanding level of field agility and comfortable ride control.

New Holland’s pioneering SuperSteer™ axle remains available on New Holland’s range of tractors from 40 to 325hp but is limited to a top speed of 40 kph.

Using a single foot pedal, the ABS SuperSteer™ allows the tractor to be steered by the brakes. Two orange pedal extensions either side of a single pedal replace the conventional, independent two-pedal arrangement. At low speed, this provides the driver with the same single-wheel steering as a conventional tractor, but automatically disables at higher speeds to prevent accidental application.

The ABS SuperSteer™ function includes tyre slip control and automatic coupling with the steering angle. This allows the tractor to perform tight turning manoeuvres without driver intervention on brakes by pivoting on a braked rear wheel, reducing the turning circle to that of a tractor fitted with a SuperSteer™ front axle. A driver-selectable amount of slip on the pivoting wheel is allowed to prevent soil damage.

The hill holder function improves tractor control on slopes, automatically engaging the brakes to prevent the machine rolling back during hill starts and easing clutch engagement.
