McCormick: Most powerful X7 Series tractors now available in Efficient spec

By WniF editors

Simpler-spec versions of the two most powerful models in the McCormick X7 series have been introduced, joining the Efficient versions of other models in the line-up that were added to the range last year.

“These additional Efficient models are being introduced at the request of operators wanting a high-performance, high-power tractor with a reasonable amount of automation but without the ‘bells and whistles’ features of the top-spec Premium models,” the sales director and general manager of AgriArgo UK, the McCormick distributor in Great Britain and Ireland, Ray Spinks, said.

The Efficient specification was introduced last year on 143hp to 166hp four-cylinder models in the McCormick X7 Series, and on a pair of six-cylinder tractors – the 160hp X7.650, which itself was a new addition to the range, and the 165/175hp X7.660.

Now, it’s also available on the X7.670, which has 177hp for draft work boosting to 192hp for PTO implements and towing trailers, tankers and spreaders, and on the X7.680, with 188hp rising to 212hp.

Standard specification for the new models includes three mechanical spool valves plus one electric valve; 123 lit/min load-sensing hydraulics plus a 44-lit/min pump dedicated to steering and ancillaries; the 24×24-speed Pro Drive transmission; four-speed PTO with “economy” as well as “power” gearing; and 9,300kg rear lift capacity.

Inside the spacious Premiere cab, which has manual instead of climate control air conditioning, there’s a swivelling air suspension driver’s seat and a hide-away passenger seat. Outside, 10 work lights illuminate the tractor’s surroundings.

Efficient spec tractors have controls for the transmission, PTO and hydraulics located on the side console.

In place of the seat-mounted armrest console found on full-spec Premium versions is a neat layout of main controls 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 comfortable multi-function joystick that carries a roller switch for easy linkage lift/lower and buttons for the engine speed memory and manual or auto road/field transmission shifting.

Another two buttons regulate the single electric spool valve fitted; the optional mid-mounted electric valves for operating a 3,500kg front linkage or a McCormick MPower loader are handled by a small, fully integrated joystick.

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 (2,820mm versus 2,750mm), more weight (3,055kg versus 2,920kg before ballast) and the ability to run on taller tyres (42-inch versus 38-inch) – all of which helps exploit the greater power and torque available.

They also have the same highly effective semi-powershift transmission as their Premium counterparts, with its smooth, adjustable power shuttle, four-speed powershift and electronic manual or auto range shifting.

“The transmission is constantly highlighted by operators as an attractive feature of the McCormick X7 tractors because of its progressive gearing, silky smooth powershifts and effective road and field auto functions,” Mr Spinks added.

A 50km/hr option, packaged with hydraulic cab and multi-link front axle suspension, can be added to the final specification, together with air trailer braking.
