T5 & T6 DYNAMIC COMMAND TRANSMISSION ew Holland first took to the centre stage with advanced transmission design back in 2009 with the pioneering solutions introduced in its Auto Command constantly variable gearbox, this in-house design and built transmission was the first step into dual clutch technology. Today, the company has changed up a gear, it now uses the same dual clutch idea in its new concept within the 110 to 180 horsepower sector.

the T6 family. The Dynamic Command is simple and efficient to use. Combining a simple semi-power shift with automotive style gear changes and user-friendly operation, the operator can choose manual or automatic modes to maximise both comfort and efficiency. Dual Clutch technology is made up of two separate clutches on two separate drive shafts within the transmission, ‘It has been carefully designed to make a Synchromesh gearbox act and feel like a full line variable transmission in the field” says David Redman High Horsepower Tractor Product Specialist, “It works by utilizing the 2 clutches in synchronization, one clutch controls the odd gears 1,3,5,7 and the second the even gears 2,4,6,8. This means the transmission can change gear without any torque and power interruption to the wheels in a
very seamless way.” The power is transferred between the two clutches in a seamless and straightforward way; when an odd gear is disengaged by one clutch, the even gear is engaged by the second clutch within milliseconds, ensuring smooth shifting and no loss of power says David. One feature is Smooth Shift, this can be likened to racing motorcycles, it blips the engine throttle a few RPM to perfectly align the synchronizers in the transmission for an uninterrupted shift. Link this to the Kick Down feature, where the tractor will downshift and increase the engine revs when under load, and the operator has the ideal transmission for road haulage.
