70 Series Combines Residue Management
70 Series Combines Residue Management
The Power to Spread...up to 50 Feet.
Chop, drop, size and spread: all with 70 Series residue handling Chopped, dropped, fine-cut or rough-cut…the 70 Series STS Combines feature residue handling systems and options that are designed to address your residue management needs without sacrificing valuable engine horsepower. For starters, the 9670 STS, 9770 STS, and 9870 STS all feature our 12-vane widespread tailboard. Perfect for spreading residue in widths to 30 feet, this simple, economical design is easy to adjust, and easy to swing up and out of the way for windrowing.
The optional PowerCast™ tailboard uses two powerful hydraulic motors to drive the variable-speed impellers. The impellers engage the residue coming out of the chopper, and give a powerful spreading ‘boost’ to the residue stream. With PowerCast, you can achieve a controlled spread of up to 50 feet wide! A twin-rotor straw spreader is driven by two hydraulic motors for uniform distribution of both straw residue and chaff. There are no belts to adjust, no belt-slippage. A 150- to 500-rpm disk speed lets you vary the spread width to match the width of your header. The straw spreader can be quickly raised out of the way to windrow straw for baling.
Growers who need a fine chop will appreciate the finecut chopper. The chopper blades, along with unique air shrouds in the chopper housing, give an ultra-fine cut while generating a strong blast of air for more even residue distribution. For growers who need an ultra-wide, fine-tuneable spread, there’s the PowerCast™ tailboard. Its deep, rotating impeller blades provide better engagement of the residue for a more even spread, even at widths up to 50 feet! Spread width is easily controlled from the CommandCenter armrest display.
Chopper blades feature large surface wings with long lasting, wearresistant material. The wings are positioned to generate maximum airflow to the outer edges of the chopper, giving you a more consistent spread pattern. Fewer blades make for reduced power requirements and lower replacement costs.
