Power Shift and VT-Drive
All models of the X7 Series are powered by new BETAPOWER diesel engines that are EPA Tier 4 compliant. Engines are equipped with turbocharging and intercooling, and common rail direct fuel injection that maximizes performance and develops massive torque to get work done. To help meet the tough EPA emissions regulations, these BETAPOWER engines use advanced selective catalytic reduction (SCR) technology, an exhaust gas after-treatment technology that reduces harmful exhaust emissions without compromising the tractor's performance. SCR technology utilizes diesel exhasut fluid (DEF) that is injected into the exhaust stream where it reacts with the hot exhaust gas to significantly reducing harmful NOx emissions. SCR technology is simple, reliable, and allows the engine to run at its peak performance without comprimise.
Both models incorporate the PowerPlus feature where the engine can "boost" horsepower when certain operating conditions are met. During heavy PTO operations, such as pulling a large baler or hay mower, or during high speed transport operations, the BETAPOWER engine will generate additional horsepower and greater torque levels to pull through tough spots and keep the machine working.

The VT-Drive is a continuously variable transmission (CVT) that is built by McCormick's partner ZF, a world-renowned manufacturer of transmissions and drive systems. The X7 Series with VT-Drive offers smooth, reliable performance in any application. CVT combines the efficiency and reliability of a mechanical gearbox with the infinite speeds range of a hydrostatic drive. The result is a tractor that can achieve any ground speed, from creeper to maximum transport speed, to match the needs of any job around the farm. Smooth, seamless acceleration offers great comfort while working, and also provides constant power transfer to the ground during speed changes for improved traction and greater productivity.
Along with exceptional performance, X7 VT-Drive tractors are simple to operate. Three operating modes give the operator a choice in how he/she wants to drive the tractor: Automatic Mode, Manual Mode, PTO Mode. There is even a cruise control button to allow for greater control of the tractor with a simple push of a button.
The real beneifts of a CVT are found in its versatility. The engine and transmission work together to find the right engine RPM and travel speed for the job at hand: high RPM with low ground speed for draft or specialty applications, or high ground speed with low engine RPM for efficient transport operations.
LOAD-SENSING HYDRAULIC SYSTEM
The X7 series tractors feature a closed-center load-sensing hydraulic system with a variable-displacement piston pump. This means that the pump always delivers the exact amount of oil that the system requires, instantly and on demand, thereby eliminating unnecessary power waste. The system supplies up to 32.5 gpm (123 l/min) to the hitch and remote valves.
ELECTRONICALLY-OPERATED REAR HITCH
With the raise/lower control conveniently located on the Multi-Function Controller and the main settings integrated into the right-hand console, the rear hitch guarantees precise implement control. Offering a maximum lift capacity of up to 20,500 lbs, the Category 3 rear 3-point hitch is equipped with lower link draft sensing to handle precise tillage work with ease.
The X7 tractors can be fitted with up to six remote valves for controlling implements and attachments on premium configurations. Simple controls make operation convenient and precise. An available mini joystick controls the front lift and front remote valve if equipped. All valves can be set to operate for specific flow rates and flow times to meet specific hydraulic tasks. Hydraulic power beyond is also built in for those implements that require a dedicated oil supply but have their own valve system.
