The three-range, eight-speed transmission is available in both 40km/h and 50km/h on the T6 range and 40km/h on the T5.
Dynamic Command is designed and built in-house by New Holland, specifically to meet customer demands for a wide range of gears that perfectly combine the tractor speed with the task at hand.
“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,” said high horsepower tractor product specialist David Redman.
“It works by utiliing the two clutches in synchronization; one clutch controls the odd gears 1,3,5 andv7 and the second the even gears 2,4,6 and 8. this means the transmission can change gear without any torque and power interruption to the wheels.
Power transfer
“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.
A specific feature of note when operating the tractor is 'smooth shift', which can be likened to the technology employed on racing motorcycles.
It blips the engine throttle a few RPM to perfectly align the synchronizers in the transmission for a uninterrupted gear shift.
When further complemented by the 'kick down' feature, where the tractor will downshift and increase the engine revs when under load, this makes this transmission the ideal partner for road haulage.
Ground speed management 2 (GSM2) is an optional feature of Dynamic Command. This feature is available in three different modes: field mode, road mode and PTO mode.
Target speed
The operator is able to set a target speed for a selected task. For example, during cultivations, setting a required speed at 8km/h, and the tractor will maintain this speed by utilising the transmission gears, seamlessly changing while maximising engine torque with lower engine revs for optimum fuel consumption.
The targeted speed can be altered by moving the CommandGrip multi-controller proportional handle backwards and forwards or simply by pressing the cruise/auto function button.
GSM2 can be ordered from the factory at the time of build or hardware allowing can be unlocked via software.
An additional feature allowed by the design of the transmission is named 'dynamic start stop'.
This offers the operator the ability to control the tractor on the brakes without depressing the clutch pedal, just like driving an automatic car.
This feature is especially when entering up to a stack or edging up to a feed barrier with a front loader. Once the task is dealt with, the operator can simply release the brake pedal and drive will be resumed.
David said: “Our Dynamic Command transmission can be described as like a Swiss army knife. The transmission has all the tools for any application around the yard, on the road or in the field.
"Ideally suited to the most experienced operator and equally intuitive to the new starter, the overlapping speed ranges in each gear ensure maximum efficiency and operator comfort.
"The extra benefit is to the customer’s pocket - with the Dynamic Command transmission giving low cost of ownership due to proven fuel efficiency through independent DLG testing.”
New Holland marketing manager UK/ROI Mark Crosby confirmed that the first T5 Dynamic Command units are now arriving at dealerships for demonstrations this autumn.
“To celebrate the 125th anniversary of New Holland, we have a special €1,250 customer bonus on a limited number of T5.140 and T6.180 Dynamic Commands available for sale within 2020.
"There has never been a better time to upgrade, with deferred payment on our retail finance available until May 2021, ideally suited to reduce winter cashflow demands.”
