With the X7.660, McCormick offers a model from the X7 series. The engine delivers 161 hp (118 kW), has 6 cylinders, with a displacement of 6,728 cm³. Rated speed is 2,200 rpm. The machine is 5,260 mm long, 2,430 mm wide and 2,920 mm high. The unladen weight is 7,200 kg. The wheelbase measures 2,820 mm. Ground clearance is 485 mm. Lifting capacity is 6,300 kg. The engine is water-cooled. The fuel is diesel. Rated output across the McCormick range ranges from 8.1 to 230 hp; the X7.660 sits in the upper part of that range with 161 hp. Its immediate neighbours are the MTX150 below it with 152.3 hp and the MTX165 above it with 161.8 hp. Unladen weight across the McCormick range ranges from 594 to 10,040 kg; here the X7.660 sits in the upper part of that range with 7,200 kg. 381 McCormick models across 40 series are on record.

McCormick X7 – the large range from Argo Tractors above the MC Power6 class: X7.660 and X7.670 with 6,728 cm³, 118 to 129 kW (161 to 176 hp), lift capacity 6,300 kg, length with front weight 5,260 mm

The X7 range forms Argo Tractors’ large class above the MC Power6 and is designed for heavy implements and draught work. As with the other McCormick ranges, the number after the dot marks the power step within the range, so the X7.660 and X7.670 differ mainly in the tuning of the shared six-cylinder engine.

The register lists 2 versions with 118 to 129 kW (161 to 176 hp) from six-cylinder engines of 6,728 cm³, an unladen weight of 7,200 kg and a gross weight of 12,000 kg; lift capacity is 6,300 kg, length with front weight fitted is 5,260 mm, width from 2,430 mm and height 2,920 mm, at a rated speed of 2,200 rpm.

With high pulling power and large lift capacity the X7 is built for large arable farms and contractors moving heavy tillage equipment, seed drills or trailers in continuous use, putting it in direct competition with large tractors from other makers in the same power and weight class.

When buying used, check operating hours and the condition of the six-cylinder’s injection system, wear on clutch, gearbox and front linkage, the condition of the front-weight mount, tightness of the hydraulics, tyre and axle condition under heavy loads, and the cab suspension; parts run through the McCormick dealer network owned by Argo Tractors.

What to check before buying

Check the hour meter against the service records — a replaced instrument is the most common gap.
Compare the data plate and chassis number with the papers.
Check the weights in the papers against the figures here — attachments change them.
Load the hydraulics and watch for sag.
Ask about parts availability for this build year — the running costs hang on it.
