McCormick has launched simpler-spec Efficient versions of the two most powerful models in the X7 series – the 177/192hp X7.670 and 188/212hp X7.680. Joining the 143-166hp 4cyl X7 and 6cyl 160hp X7.650 and 165/175hp X7.660 Efficient models launched last year, the two new models are aimed at operators wanting a high-performance, high-power tractor with a reasonable amount of automation but without the ‘bells and whistles’ from the top-spec Premium models. Standard specification for the two X7 Efficient models includes three mechanical spool valves plus one electric valve; 123l/min load-sensing hydraulics plus a 44l/min pump dedicated to steering and ancillaries.
The cab has manual instead of climate control air conditioning, and in place of the seat-mounted armrest console found on full-spec Premium versions, the layout of main controls is located to the driver’s right. On either side of the dials used for setting up and adjusting the electronic rear hitch are levers for the mechanical spool valves, pto speed selection and the optional creep gearbox, which takes the total complement of ratios to 40 forward and reverse. Ahead of them is the multi-function joystick, which carries a roller switch for linkage lift/lower and buttons for the engine speed memory and manual or auto road/field transmission shifting.
Although the X7.670 and X7.680 use the same 6.7-litre BetaPower engine and cast chassis as other six-cylinder models in the range, these are bigger, beefier tractors. They have a longer wheelbase, more weight and the ability to run on taller tyres. They also have the same semi-powershift transmission as their Premium counterparts. A 50kph option, packaged with hydraulic cab and multi-link front axle suspension can be added to the final specification, together with air trailer braking.
