McCormick X4 and Landini 4 were updated in the autumn of 2017. The model range was still divided into two segments. The smaller models had a 2.9-liter engine and a 210 cm wheelbase. The larger ones had a 3.6-liter engine and a 223 cm wheelbase. The engines were now Tier 4 Final compliant Deutz engines. The engines featured common rail injection, exhaust gas recirculation, and an intercooler.

The transmission, developed from the previous version, had 12+12 gears and, when equipped with a creeper gear, 24+24 gears. Power Shuttle versions had a hydraulic direction reverser with potentiometer control. The same package included a push-button clutch and a hydraulic PTO engagement. An Eco transmission (40 km/h at 1900 rpm) was also available. The larger models had a locked front axle and front wheel brakes as an optional extra. The cab was four-post. The roof structure was very low-profile. The model range was also available without a cab.
