Ag machinery maker John Deere has released details of the new 5M models set to hit the New Zealand market next year.
Equipped with a 7.4 litre “long stroke” engine – the biggest displacement in this market segment – maximum power is available at the low engine speed of 1,850rpm. Meanwhile, maximum torque stays consistent between 1,000 to 1,500rpm.
Valtra’s EcoPower system has been applied to the entire Q Series range, further reducing fuel consumption, with maximum driving speed is achieved at only 1,500rpm.
The Q Series’ AGCO CVT uses electronic transmission management that automatically selects the lowest possible engine revs for the work to maintain the lowest fuel consumption. It also distributes the power accordingly to the hydraulics, PTO, or transmission.
Weighing in at a claimed ideal of 9.2 tonnes, the maximum gross weight is 16 tonnes. This allows a high payload and legal transporting on the highway. Configured with a longer wheelbase and low overall height, the centre of gravity is kept low, making the tractor very stable.
The Aires Suspension works in combination with that long wheelbase to increase the pulling force of the tractor.
This reduces power hop – given that grip to the ground is increased because of the air suspension’s faster reaction times.
At road speeds, power is transmitted almost purely mechanically. This delivers fast and smooth acceleration, with the cab and the front axle air-suspension systems ensuring a smooth ride in any environment.
