Case IH Steiger/Quadtrac 400-600

In 2010, the Case IH Steiger lineup received Tier 4A/Stage 3B-compliant engines that were slightly more powerful than before. At the same time, the lineup was expanded with a new, larger model. All models now featured in-house Cursor engines. The smallest model, the 350, had an 8.7-liter engine, while the others had 12.9-liter engines. Urea injection was used to reduce emissions. The two largest models had common rail injection, while the others used pump nozzles.

QuadTrac models equipped with rubber tracks were available for the four largest models. The transmission was still a 16+2-speed full powershift, featuring APM automation, which automatically adjusted gear shifting and engine speed. There were several hydraulic pump options available, with the Twin Flow version being more efficient than before (428 liters per minute). The user interface was similar to that in the Magnum series: gauges were located on the front pillar, and controls were on the armrest and touchscreen. The noise level was still reported to be 75 dB. Standard equipment in Europe included cab coil suspension, headland automation, automatic climate control, a heated active seat, leather upholstery, and auto-steering readiness. The power take-off and three-point hitch were optional extras.

In autumn 2013, the lineup transitioned to engines compliant with the Tier 4B/Stage 4 standard and model numbers ranging from 370 to 620.
