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
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
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
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
Power-Packed Engines Emission-compliant, biodiesel-approved engines provide muscle to handle heavy loads, wet conditions and hillsides without slowdown.
Other features include:
Computer-aided-design parent bore block with contoured outer surface for increased overall block strength and reduced noise and vibration
WD1504: Four-cylinder, 4.5L (274-CID) with mechanical fuel injection
WD2104 & WD2504: Six-cylinder, 6.75-L (411-CID) with electronic fuel injection
WD4 Windrower Enhancements Whether you are cutting hay or swathing canola, extra horsepower to muscle through the tough spots is a welcome addition, especially when that power doesn’t come at the cost of efficiency. Enhancements include:
Our patented Selective Catalytic Reduction (SCR)- only exhaust aftertreatment technology to meet Tier 4 B/Final emissions requirements
Road speeds up to 24 mph
Updated hydraulic steering system
Improved field drivability
Dual-circuit hydraulic system
Integrated AFS Pro 700 control center
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.
