PALMERSTON NORTH – (5th June 2018) – New Holland Agriculture is introducing a major upgrade to the T7 Long Wheel Base (LWB) range in the shape of a new suspended front axle.
New front axle and steering control, precision at high speed
The new axle is targeted to ease the operator’s life whilst driving at high speed. The combination of new axle geometry, low friction hub bearings and a new hydraulic steering unit delivers superb feedback and control to the driver. The self-centring characteristic designed into the axle reduces steering corrections to a minimum, especially at high speed, reducing operator fatigue.
Upgraded TerraGlideTM front axle suspension featuring ‘Skyhook’ logic delivers stability and improved comfort
In combination, the tractor’s front suspension has also undergone a major update. To provide improved performance over the wide variation of front axle loads encountered on a tractor, a new control valve with dual accumulators had been added. In situations where the tractor is carrying a heavy rear implement the new suspension mechanism delivers an 11% improvement compared to the existing design, when measuring chassis vibration.
The T7 LWB utilises a suspension concept known as ‘Skyhook’. This active system, normally found on sports cars, aims at maintaining the tractor in a level condition irrespective of external forces. These forces typically would be an implement being raised or lowered, or the tractor braking or accelerating; actions where weight can be transferred on and off the front axle causing instability. The logic of the T7 is to momentarily stiffen the suspension if the operator brakes, accelerates or operates the three point linkage. The upgraded T7 goes as far as weighing the rear implement to determine how stiff to make the suspension to reduce the risk of excessive suspension travel at high speed. An accelerometer unit within the nose of the tractor monitors any chassis movement caused from uneven surfaces and continually adjusts the suspension damping. This advanced control results in a very stable vehicle, for the driver this means improved safety and comfort.
Depending on operator preference the suspension can be operated in Soft, Normal or Hard modes with a greater difference being introduced between the settings when compared to the current suspension.
New CustomSteerTM variable ratio steering, effortless manoeuvring
For model year 2018 CustomSteer brings a unique variable ratio steering concept to T7 range. The driver is able to vary the number of rotations of the steering wheel it takes to turn the axle hubs from lock to lock. There are three selectable settings ranging from a single rotation of the steering wheel, 1:1, to 2:1 to 3:1. On tractors with the IntelliViewTM IV monitor the driver can select their own ratio and even a different ratio for forward than reverse.
Operators will see the benefits of the CustomSteer in a wide range of tasks, such as manoeuvring during front end loader work or turning faster with less effort on short headlands whilst ploughing or drilling. Meanwhile, an aggressive 1:1 setting in reverse makes easy work of the steering when reversing with a trailer. For the ultimate control over the steering the ratios can be changed automatically within the headland turn program, HTS II. One ratio for working, one for turning at the headland, one for reversing and all switched automatically.
For safety at high speeds any chosen custom ratio is gradually dialled out as speed increases, up to 26kph, slow the tractor down and CustomSteer will automatically reengage.
Upgraded vehicle capacities for higher payloads
In addition to these key updates comes a higher vehicle capacity for the T7 LWB with regards to Gross Vehicle Weight, now as high as 14,000 kg resulting in higher payloads for customers.
Updated instruments providing clearer information
An updated front instrument cluster, featuring white backlighting and blue needles for the gauges, refreshes the front console. While for the IntelliView IV monitor a new intuitive graphic illustrates the selectable upper or lower engine values that can be chosen for the Auto Command™ transmission’s working limits.
For drivers wishing to monitor closely an operation, a camera-ready option allows up to three camera feeds to be connected at the rear of the cab and their images displayed on the IntelliView screen.
