A new range of powerful stepless transmission tractors will be represented by the top model in a new-look line-up making its UK debut on the Argo Tractors stand at the LAMMA show in January.
The McCormick X7.624 VT-Drive with up to 230hp for work draft and 240hp for pto-driven implements and road transport is the most powerful model in the latest X7 Series, which also features lower running hours, at more comprehensive 360deg LED lighting packages set in a new cab roof panel, and new control features in the Premiere cab.
The X7.6 VT-Drive tractors have highlighted their new levels of performance potential, the X6 VT-Drive flagship models.
Adrian Winnett, managing director of Argo Tractors operations in the UK and Ireland, said: the McCormick range.
“Our previous CVT models in the X7 Series peaked at 195hp; with the X7.624 VT-Drive they go to 240hp, giving farmers and contractors a very powerful and versatile package with all the performance and driver-comfort attributes of a stepless transmission. “
McCormick X7.6 VT-Drive series
The complete line-up of new McCormick X7.6 VT-Drive tractors includes the X7.620 VT-Drive with 185hp draft power and 195hp for transport and pto-driven implements such as power harrows and tillers.
The X7.621 VT-Drive serves up 200hp and 201hp, while the X7.623 VT-Drive puts 215hp and 225hp at the operator’s disposal.
McCormick Betapower 6.7-liter engines by FPT are supported stress-free in a cast iron front chassis which provides front-end weight for optimum traction, and V emissions-compliant is achieved through a revised SCR AdBlue oxidation catalyst (DOC) – no DPF is required.
The latest-spec engines also feature optimized fuel filters and a comprehensive filtration system, which allowed a significant contribution to reduced running costs.
Running cost savings can be made by using the engine braking system, which is an electronic motorized valve on the turbocharger and is operated by a button on the cab floor.
Dynamic engine braking can be used to improve the safety of the car.
McCormick X7.6 VT-Drive transmission
Power and torque from the McCormick X7.6 VT-Drive tractor’s higher output engines are channeled through the new ZF Terramatic TMT20 transmission.
This uses four planetary gear sets, wet clutches and hydraulic speed variation to provide the finest possible ground speed adjustment.
Control software developed by Argo Tractors makes the system easy to use by experienced and experienced CVT tractor drivers alike, with a choice of management modes providing optimum engine and transmission control strategies for different fieldwork and transport situations.
Four working speed bands can be set by the operator through the 12in Data Screen Manager display in the cab, and manual control is available through the accelerator pedal and Easy Pilot proportional controller.
Heavier duty rear axle and power take-off assemblies handle the higher power and torque outputs, and a four-speed package with ‘power’ and ‘economy’ 540rpm and 1000rpm gearing, contributes to the tractor’s impressive performance and fuel-economy credentials.
Control and DSM display upgrades
The neat, simple and uncluttered design of the premier cab interior with the latest models but with control enhancements to further improve the ease of use
On the seat-mounted control console of These premium specification tractors, the unique ‘mySwitch’ concept of a single button on the Easy Pilot hand controller That can operate four different tasks Has Been extended with a Further four to Which operators can allocate various hydraulic and other functions as they see fit.
For easy use, the supplementary MySwitch buttons are positioned around the roller thumbs switch to rapidly lift and lower the 9300kg rear implement hitch.
Like, the double-acting spool valves – three are standard, up to seven options – can be allocated to the armrest or to the mini joystick, which is typically used for operating the loader or the 3500kg front hitch.
New headland management features include dedicated command buttons on the armrest for quick and easy access to record, edit or engage previously recorded drivers and implement control sequences for different implements.
The headland management system is designed to minimize the operator’s workload during headland turns; and so is McCormick Easy Steer, which reduced by number of steering wheel turned to lock to lock.
Easy Steer is available with factory-installed satellite Precision Management Steering, which offers a number of Topcon Agriculture display terminals, precision farming app and accuracy options through McCormick dealers.
The Premiere cab can be upgraded to the semi-active hydraulic system with damper settings.
Both systems complement the smooth-riding and field-traction-enhancing characteristics of the front axle with its parallel link
