LAMMA preview McCormick unleashes more powerful

cCormick’s new range of more powerful step- less transmission trac-
tors will be represented by the top model in a new-look line-up on the Argo Tractors stand at LAMMA. Boasting up to 240hp, the Mc-
Cormick X7.624 VT-Drive is the most powerful model in the lat- est X7 Series – which also features lower running costs thanks to en- gine service intervals extended to 1200 hours, a more comprehen- sive LED lighting package and new control features. To emphasise their new lev- els of performance potential, the X7 range of tractors have a more purposeful chiselled-jaw appear- ance in the same style as the larg- er 264-310hp X8 VT-Drive fl agship models.
Argo UK managing director
Adrian Winnett says: “The push for more performance is relentless so Argo Tractors has taken the op- portunity when switching to Stage V emissions-compliant engines to introduce more powerful VT-Drive models to the McCormick range. “Our previous CVT models in the X7 Series peaked a 195hp; with the X7.624 VT-Drive they go to 240hp, giving farmers and contractors a very powerful but versatile package with all the per- formance and driver-comfort at- tributes of a stepless transmis- sion.”
Power options
The complete line-up comprises the X7.620 VT-Drive with 180hp draft power and 190hp for trans- port and pto-driven implements such as power harrows and till- ers. The X7.621 VT-Drive serves up 200hp and 210hp, while the X7.623 VT-Drive has 215hp and 225hp.
McCormick Betapower 6.7-li- tre engines by FPT are support- ed stress-free in a cast iron front chassis that also provides front- end weight for optimum traction. Stage V emissions compliance is achieved through a revised Ad-

Blue injection system in combi- nation with a diesel oxidation cat- alyst.
The latest-spec engines also feature optimised fuel fi lters and a more comprehensive oil fi ltra- tion system, which together with a new engine oil specifi cation has al- lowed service intervals to be dou- bled from 600 hours to 1200 hours, making a signifi cant contribution to reduced running costs. Running cost savings can also be made by using the engine brak- ing system, says Argo. This ma- nipulates an electronic motorised valve on the turbocharger and is operated by a button on the cab fl oor.
Dynamic engine braking can be used to ease reliance on the service brakes and so extend the working life of the friction mate-

It’s a powerful package with all the performance and driver-comfort attributes of stepless transmission
Transmission Power and torque from the Mc- Cormick X7.6 VT-Drive tractor’s higher output engines are chan- nelled through the new ZF Terra- matic TMT20 transmission. This uses four planetary gear
sets, wet clutches and hydrau- lic speed variation to provide the fi nest possible seamless ground speed adjustment, with high lev- els of mechanical effi ciency across the zero to 50kph envelope. Control software developed by
Argo Tractors makes the system easy to use by inexperienced and experienced CVT tractor drivers alike, with a choice of manage- ment modes providing optimum engine and transmission control strategies for different fi eldwork and transport situations. Four working speed bands can be set by the operator through the 12in Data Screen Manager dis- play in the cab, and manual con- trol is available through the ac- celerator pedal and Easy Pilot proportional controller. Heavier duty rear axle and power take-off assemblies han- dle the higher power and torque outputs, and a four-speed pto
package, with ‘power’ and ‘econ- omy’ 540rpm and 1000rpm gear- ing, contributes to the tractor’s impressive performance and fu- el-economy credentials.
Control upgrades The neat, simple and uncluttered design of the Premiere cab interior continues with these latest models but with control enhancements to further improve ease of use – in- cluding electric steering wheel tilt adjustment.
On the seat-mounted control console of these Premium speci- fi cation tractors, the MySwitch concept of a single button on the Easy Pilot hand controller that can operate fi ve different tasks has been extended with a further four to which operators can allo- cate various functions. For easy use, the supplemen- tary MySwitch buttons are posi- tioned around the roller thumb switch used to rapidly lift and lower the 9300kg rear imple- ment hitch. Similarly, each of the electric double-acting spool valves – three are standard, up to seven optional – can be allocated to the armrest console paddle switches or to the mini joystick, which is typically used for operating a loader or the 3500kg front hitch.
The new more powerful McCormick X7.6 VT-Drive tractor range will make its UK debut at LAMMA
