Efficient Power

The WD4 series windrowers offer engines with Case IH Efficient Power technology. Windrower field tests have demonstrated a minimum of 10 percent operating cost advantage compared to similar Tier 3 windrowers. The 4-cylinder WD1504 and 6-cylinder WD2104 and WD2504 deliver 150, 210 and 250 horsepower, respectively. The windrowers are equipped with our patented Selective Catalytic Reduction (SCR) - only exhaust aftertreatment technology to meet Tier 4 B/Final emissions requirements. Because it does its work outside the engine, in the exhaust system, the engine can be tuned to operate at its peak power and fuel efficiency.

Up To 24mph Road Speeds

WD4 windrowers also boast road speeds of up to 24 mph, so you can be more efficient and get another field cut before calling it a day.

Hydraulic Steering System

The hydraulic steering system reduces the number of mechanical linkages required, creating tighter and more responsive steering. The system makes the machine easier to steer, especially at high road speeds.

Improved Field Drivability

These steering system updates have also improved drivability in the field. WD4 windrowers better follow the AB line when AFS AccuGuide™ autoguidance is activated. Case IH engineers adjusted the machine’s weight balance and developed caster wheels, set at a 3-degree angle.

Dual-Circuit Hydraulic System

The dual-circuit hydraulic system with two 40-gallon-per-minute (gpm) pumps results in faster cutting speeds while maintaining a clean-cut and well-formed windrows. The hydraulic system also runs cooler and more efficiently, maximizing machine performance in draper applications.

Advanced Farming Systems

Case IH windrowers use the integrated AFS Pro 700 control center to not only manage windrower autoguidance functions, but also to control key machine functions and monitor windrower performance.

Straightforward Operation

• Integrated AFS AccuGuide autoguidance simplifies steering
• AFS Pro 700 control center display controls guidance and machine functions and serves as a performance monitor
• Hydraulic steering provides tighter control while retaining light-touch steering
• Simplified flotation system allows adjustments to be made on the fly
• Easy header hook up with wider lift arms

Maximum Uptime

• Redesigned hydraulic steering system provides more stability with fewer mechanical linkages and pivot joints
• Independent rear suspension supplies optimal rear axle stability and flotation, even in rugged terrain
• Redesigned hydraulic system runs cooler and more efficiently, maximizing machine performance

Rear Axle Stability

• Re-designed rear axle for ultimate control and stability
  • Rear wheel forks are three degree cast design for optimal stability
  • Independent rear suspension is now base equipment for all models
  • Larger 16.5L rear tires provide better flotation and better ride

Header Operation

• The flotation system has been simplified by adding sensors to the cut height cylinders which eliminates the header drop rate setting in the cab
• Header installation/removal is easier with power down option and wider lift arms to improve visibility
• Power down feature – Lift arms can be lowered all the way to the ground without making adjustments to flotation

Hydraulic System

• The Dual Circuit Hydraulic System on draper machines have improved hydraulic efficiency and capacity
• Features two 40 GPM pumps for matched capacity to header
• Higher flows through the cooling system and new filtration for cold weather applications
• New couplers for matched capacity flow requirements

Integrated Guidance Option

• Guidance Complete – display, receiver and navigation controller; WAAS or HP/XP
• Auto-guidance ready is standard equipment and includes wiring harness and the bracket to mount the receiver on the roof
• If needed, machines can be ordered without auto guidance

Improved Steering Control

Redesigned steering system that provides tighter control while retaining light touch steering

• Fewer mechanical linkages
• Eliminated wearable pivot joints
• Hydraulic steering system provides quicker response time needed for high speed transport and guidance
• Aggressive maneuver function that slows machine when steering control is minimized

AFS Pro 700

• Operational information is displayed on the right. Coupled with the after-market GPS package, the left side of the display can show GPS information.
• All machine functions and operation information is available in one display.
• Display can perform diagnostics
• Optional rear camera kit can be added and run through the AFS Pro 700 display.
