The new model in the high-end range of Case IH crawler tractors — the Quadtrac 715 AFS Connect — has become the world's most powerful serial tractor with a capacity of 778 hp/572 kW.

This was reported by the press service of Case IH.

The manufacturer notes that the machine combines many design features of Quadtrac, tested for nearly three decades, with completely innovative solutions and key improvements compared to other models in the recently released lineup of updated 525–645 Quadtrac AFS Connect and 475–525 Steiger AFS Connect tractors.

"We aimed to create a machine that meets the demands of the largest farms in our region, operating with implements at optimal speed, ensuring the highest productivity, and enabling operations at the right time, even under the most challenging working conditions, to make the most of short weather windows. We also wanted to protect the soil with a larger contact area and fewer passes, which also means greater processing efficiency and minimal field ruts."

— Franz Josef Silber, Product Marketing Manager for high-power and all-wheel-drive tractors at Case IH.

The 715 AFS model is only available in the Quadtrac track format. According to Case IH, the machine is equipped with the industry's first advanced FPT Cursor 16L TST engine. Its displacement is 23% larger than the Cursor 13L TST model of the Quadtrac 645, providing peak power of 778 hp at 1900 rpm and peak torque of 3255 Nm already at a low 1400 rpm.

High torque is ensured by a two-stage turbocharging system with intercooling, guaranteeing a quick response to load under heavy conditions. Refueling stops are reduced thanks to wider saddle tanks installed on the rear frame, holding a total of 1968 liters of diesel, 11% more than the Quadtrac 645.

The tractor is equipped with the latest 16-speed PowerDrive transmission from Case IH, featuring an automatic performance management (APM) system. PowerDrive was first introduced in the recently launched Quadtrac AFS Connect series and features improved core design components.

The new tracks on the Quadtrac 715 are designed for operation in heavy conditions and differ significantly from the tracks on other Quadtrac models. The track length has been increased by 305 mm, which, according to the manufacturer, ensures better ground contact, improves power transmission, increases traction, and reduces compaction.

The drive wheel diameter is 1008 mm compared to 910 mm on the previous model, with five lugs instead of four, allowing for higher torque and maximizing track lifespan.

Externally, the new Quadtrac 715 differs from its counterparts with a new hood design. The hood can be raised 31% higher (34° versus 26°) for improved service access and opens and closes using an electric drive, controlled by a switch in a lockable box next to the cabin steps.

In addition, the tractor features a new lighting design: new LED road and work lights have a power output of 25,420 lumens, which is 11% more than the previous version. These are complemented by new work lights mounted on top of the cab. These lights are available in three configurations, with the top configuration providing an additional lighting power of 45,600 lumens with 360-degree coverage.

The Category 5 drawbar fully matches the load capacity of the new tractor, and the optional Category 4 three-point hitch, which recently appeared on other new Quadtrac models, can lift up to 10,092 kg and was initially designed with the Quadtrac 715’s capabilities in mind.
