Steiger Series
Steiger is Case IH's articulated and tracked 4WD high-horsepower platform for large-acreage tillage, seeding, and heavy-drawbar operations. The series includes wheeled, Rowtrac, and Quadtrac configurations with top-end output and high-flow hydraulics.
Peak Power at Scale
Case IH publishes Steiger with peak horsepower from 467 to 853 HP, including the 785 Quadtrac at 853 peak HP. Engine architecture spans 12.9 L and 15.9 L FPT platforms for sustained heavy-load duty. Model highlights include Steiger 645 with peak horsepower listed at 699 and Steiger 715 at 778 peak. This output range positions Steiger for high-acreage primary tillage, large air-seeding systems, and long pass operations where consistent draft power and traction are critical.
- •Published peak horsepower range: 467–853 HP
- •Steiger 785 peak horsepower: 853
- •Steiger 645 peak horsepower: 699
- •Steiger 715 peak horsepower: 778
- •Engine families: 12.9 L and 15.9 L
Transmission Options for Heavy Draft
Steiger offers two transmission strategies to match operation style: a proven full powershift and CVXDrive continuously variable option. Case IH specifies a 16-speed full powershift architecture and positions CVXDrive for tough operations needing exact speed control. This gives producers flexibility between familiar stepped-shift behavior and continuously variable driveline management. Both are built for high-load field conditions where maintaining momentum, reducing wheel or track slip, and preserving efficiency under changing soil resistance directly affect acres covered per day.
- •Transmission options: powershift or CVXDrive
- •Powershift configuration: 16-speed full powershift
- •CVXDrive offered for exact-speed heavy operations
- •Designed for field or road high-load transitions
Hydraulic and Axle Capacity
Steiger hydraulic systems are engineered for very large implements and high continuous flow demand. Case IH lists up to 113 gpm hydraulic flow with up to 8 remote valves available. Axle and chassis details include heavy-duty axle capability up to 72,000 gross vehicle operating weight and a 50/50 front-rear weight split target for traction with lower compaction risk. This makes the platform suitable for broad-acre drills, large tillage tools, and high-hydraulic-flow attachments across long daily operating windows.
- •Maximum hydraulic flow: up to 113 gpm
- •Remote valves: up to 8 available
- •Gross vehicle operating weight handling: up to 72,000
- •Published 50/50 front-rear weight split design
Track Performance and Uptime
Quadtrac configurations in Steiger prioritize traction, flotation, and ride consistency across variable field conditions. Case IH notes optional heavy-duty suspended undercarriage with increased roading speed up to 26.5 mph on compatible Quadtrac setups. Service and ownership support include a published 3-year, 2,000-hour factory warranty and integrated connectivity tools for monitoring and support. This combination helps large operations keep primary tillage and seeding units moving with fewer interruptions during compressed seasonal work windows.
- •Quadtrac optional suspended undercarriage available
- •Published roading speed with HD suspended undercarriage: up to 26.5 mph
- •Factory warranty: 3 years / 2,000 hours
- •Integrated connectivity and FieldOps support highlighted
