X7 VT-DRIVE

Each McCormick tractor reflects the passion and dedication of those involved in designing testing and producing this superb range of tractors. The new X7 VT-Drive tractors offer the ultimate in style, technology, operator comfort and productivity. Five models in the range are all powered by the new Betapower Fuel Efficiency four-and six-cylinder turbo engines with multivalve technology and common rail injection system. These engines meet Tier 4 Interim emission regulations using the SCR system, an exhaust gas after-treatment technology that reduces exhaust emission without compromising engine performance. The X7 models with VT-Drive continuously variable transmission feature five engines with power ratings of 136, 150 and 166 hp for the four cylinder and of 172 and 181 hp for the six cylinder. The VT-Drive transmission is a continuously variable transmission (CVT) that provides an infinite number of speed ratios from zero to the maximum speed permitted in the country of use. Both transmissions feature a left-hand steering-column power shuttle and are controlled electronically via pushbuttons located on the multi-function armrest. The electro hydraulically-engaged rear PTO features an exchangeable shaft providing 6 or 21 splines and offers four speeds 540/540E/1000/1000E rpm. The electronic control of the PTO always ensures smooth and modulated implement start-up. The system also incorporates PTO headland management to eliminate implement drive line damage when raising the machine  The X7 VT-Drive models are available with closed-centre hydraulic system with variable-displacement pump. The electronically-controlled rear hitch with draft sensing on the lower links provides a maximum lift capacity of 9300 Kg and allows a precise control of the implement. Also included is a Ride Control system to help protect the implement and reduce shock loadings on the tractor during transport. A radar sensor is also available for operations where true ground speed is required, this can also be used in difficult ground conditions to improve tractive performance and reduce wheel slip. True versatility can be obtained with a front hitch capable of lifting up to 3500 Kg and a front PTO. Lift & Lower switches are provided at the front to assist in connecting or disconnecting front implements. The front axle, either rigid-mounted or with electronicallycontrolled independent suspensions, offers a 55° steering angle, providing excellent manoeuvrability in confined spaces. The Premiere Cab is a true high-tech control centre that allows the operator to work the tractor with maximum ease and comfort. The cab features a Data Screen Manager (DSM), standard on the VT-Drive models, and a 12” touchscreen monitor that allows the driver to control the performance and functions of both tractor and implement (ISOBUS, satellite-based guidance system etc.). The cab interior offers the operator a fully sound-proofed, functional ergonomic environment and a high-quality, automotive-grade fit and finish that further enhance the driving comfort.

BETAPOWER FUEL EFFICIENCY TIER4 INTERIM ENGINES WITH SCR SYSTEM

All models of the X7 series are powered by the new Betapower Tier 4 Interim engines. The X7 models with VT-Drive continuously variable transmission feature five engines with power ratings of 136, 150 and 166 hp for the four cylinder and of 172 and 181 hp for the six cylinder. All engines are equipped with turbocharger and common rail injection system and meet the Tier 4 Interim emission regulations using the SCR system, an exhaust gas after-treatment technology that reduces exhaust emission without compromising the tractor performance. The SCR technology utilizes a second fluid (AdBlue®) that is injected from a separate tank into the exhaust stream via an injector unit. The fluid reaches the SCR catalytic converter where it reacts with the exhaust gas, thus significantly reducing NOx emissions. The optimised electronic fuel injection and the enhanced combustion efficiency, combined with the SCR system, allow these engines to deliver exceptional power with over 40% torque backup and outstanding fuel economy, thereby making for great flexibility of use.

VT-DRIVE CONTINUOUSLY VARIABLE TRANSMISSION

The VT-Drive transmission is a continuously variable transmission (CVT) developed by McCormick that provides an infinite number of speed ratios from zero to the maximum speed permitted in the country of use. This transmission offers four speed ranges to suit different operating requirements:
RANGE 1 CREEPER 0.5 – 3 KM/H
RANGE 2 FIELD 1 0.5 – 12 KM/H
RANGE 3 FIELD 2 0.5 – 21 KM/H
RANGE 4 TRANSPORT 0.5 – 40 or 50 KM/H
The VT-DRIVE transmission features four operating modes:
AUTO MODE
The electronic unit takes control of the engine speed and transmission ratio (in accordance with the settings of the droop potentiometer integrated into the armrest) in order to achieve the required speed.
MANUAL MODE
The operator sets the engine speed using the hand throttle. The electronic unit takes controls of the transmission ratio in order to achieve the required speed.
PTO MODE
The operator sets the engine speed using the hand throttle. The electronic unit takes control of the transmission ratio in order to achieve the required speed with the PTO on.
CRUISE MODE
The operator selects the tractor travel speed and this remains constant.

PREMIERE CAB, A TRUE HIGH-TECH CONTROL CENTRE

Two years after the launch of the X7 series, the Premiere Cab has been updated with cosmetic and ergonomic upgrades to improve operator comfort and ease of operation, making long hours in the field as stress-free and comfortable as possible. The new cab retains the same design as the previous version – a four-post frame with flat-deck platform, rear-hinged doors and one-piece panoramic windscreen that provides ease of access to the driving position and unequalled all-round visibility. The Alcantara upholstered swivel seat with dynamic air suspension system and fully automatic height adjustment features an optional backrest ventilation system and a multi-function righthand armrest that houses the main tractor controls. Also integrated into the armrest is a 12” DSM touchscreen monitor that controls the tractor performance and functions. The telescopic tilt-adjustable steering wheel is designed to tilt with the instrument panel. The new cab also includes several new features as standard including an inside mirror, additional 12V sockets for portable devices, a bottle holder and a roof hatch frame. The cab is pressurized to keep a clean, dust-free environment and has a sound level of only 70 dBa, while a highly-efficient automatic climate control maintains the desired cab temperature whatever the outdoor weather conditions. To further increase operator comfort, an electronically-controlled hydraulic cab suspension system is available as an option.
