New Front Axle And Custom Steer For New Holland T7 LWB Models.

New Holland’s Basildon-built T7 LWB models have been refreshed with a new dashboard design which features white back-lighting and blue needles. The new look is complemented by a new ISOBUS configurable handgrip, more intuitive operational software and the availability of factory-fitted PLM-Connect telematics. The new T7 models also feature a switch-controlled diverter block for the push-out pick-up hitch, eliminating the need to use a spool valve.

Arguably the biggest news for many New Holland operators will be the introduction of a new upgraded Class-4 front axle, which features a new front suspension control and offers a higher load capacity. This increases the load rating for AutoCommand models to 14,000kg, and a whopping 16,800kg on heavy duty tractors.

The new skyhook front axle suspension system, which now features a double accumulator, integrates a new control logic which New Holland claim keeps the tractor level at all times, whether the tractor is carrying a load on the linkage, accelerating or braking, or traversing uneven terrain.

The system works by constantly measuring the changing operational loads and weights of the tractor, reducing chassis vibration by up to 11% when carrying a heavy load. Additionally, the suspensions programmable ride comfort control can be set at either soft, normal or hard settings depending the load or the terrain.

Another interesting design development with the new axle, is what New Holland describe as improved directional control, thanks to a steering system which now self centres. Ride is also improved thanks to the introduction of ball bearings in the hubs, which replace the bushes used in previous axles. New Holland has also improved the design of the axle seals.

A new option, which has already been introduced on T7 HD models, is custom steer. This is a programmable variable rate steering system, designed to reduce steering inputs from the standard 4.7 turns from lock-to-lock, to ratios of either one-to one, two-to-one or three-to-one at the press of a button. A custom setting also allows the operator to programme his/her own quick-steer ratio, using a slider setting on the tractor’s touchscreen monitor.

When operating in custom steer mode, as forward speed increases the steering ratio gradually reduces up to 20km/h, when it automatically shuts off. Custom steer can be programmed so that forward and reverse shuttling operations have different steering ratios, or to operate automatically in headland turn or auto-steering modes. The cost for the system is just £300 on tractors equipped with factory-fitted autosteer.
