      Resistant Coating

      • Benefit from years of experience with a new generation of strength where it counts:
      • Oil coolers protected with a Heresite coating proven to prevent corrosion.
      • All fasteners will be stainless steel where possible or if structural hardware, they will have a 525E coating. Salt spray results showed standard fasteners lasted 96 hours before rusting and those with the coating lasted 1,000 hours. 
      • All boom cylinders have a Lion1000 Chrome coating to reduce rust and pitting of the rod which will increase cylinder life by 3.5 times, reducing cost of ownership and increasing the useful life of the machine.
      • Internal O-ring seals improve cylinder life by protecting against corrosive materials.
      • Super Tough coating on hydraulic lines provide high resistance to abrasion and UV exposure along with improved O-rings.
      • These hoses are added in high stress areas to prevent failures and improve lifespan and reduce maintenance of the machine.
      • An XTR (Extreme-Resistance) coating on hydraulic fittings withstands corrosion more than 7 times longer than SAE standard of 96 hours. 
      • Used in applications where connections come in contact with nitrogen-based fertilizers and other aggressive chemicals, standard hose and tube fittings become severely corroded

Optimal spinners, optimal spreads

TerraGator® features industry-proven spinners from New Leader—designed to spread accurately and efficiently every time, all year round.

  • Four MultApplier Ready Models: Featuring wide, tapered sides for quick filling and a spread width of up to 90 ft. (27 m.). In just a couple hours, the liquid system can be easily changed out for a spinner, providing year-round usage and improved ROI.

    • Independent spinner speed control for precise and repeatable patterns and the ability to slow one spinner down using the Boundary spread feature to keep product in the field.
    • Feed gate optimizer helps determine achievable rates based on gate height.
    • Automatic belt tension eliminates the guesswork out of setting tension and increases conveyor life.
    • Centrally located front/rear grease banks mean easier access and servicing.
    • Auto-chain oiler system reminds operators of service needs at the end of the day to extend the life of the conveyor.

      40-Gallon/Minute Hydraulic Flow

      Provides the most powerful spinner system available on any high-clearance machine, allowing the TerraGator to function at higher rates and higher speeds.

      • NL5000 G5 Dry Nutrient Applicator: 16-section swath width control saves costs and places product where it’s needed via pinpoint fan-frame positioning, cutting 10–15% of overlap compared to spinner systems without section control.
        •  The G5 applicator provides an excellent return on investment in point rows or tougher conditions (terraces, small fields, rolling ground, point rows).
        • Remote spreading feature increases accuracy for independent left- or right-side spreading by eliminating application to areas where it’s not needed, such as those already covered and headlands.
        •  Last-pass spreading reduces material overlap and allows proper material placement on the last pass across the field.

Challenger® TERRAGATOR® Dry TG 8400C Bins made better

Twin or four bin, you can’t go wrong. The TerraGator® Air Spread makes complex, multi-product application consistently easy.

  • Soilection Four Bin: The ultimate system for accurately blending fertilizers, nutrients and chemicals that lets you variably apply multiple products in a single pass to significantly reduce operating costs.
  • Rates: Each bin can individually vary and dispense product rates of 25 lbs. per acre up to 860 lbs. (390 kg.) per acre* while utilizing independent, hydraulic-controlled metering chains for true variable-rate application.
  • Spread Pattern: 70-foot (21.3 m) with double-overlap coverage delivers multiple products faster and more precisely in one application.
  • Section Control: Shut down sections of the boom to reduce spread pattern by 50% for less waste, better accuracy and improved environmental stewardship.
  • Calibration: Coefficient of variation (COV) of 5% or less ensures the most accurate system from the factory. Adjustable settings can lower the COV even further for sensitive crops.
  • Optional Micro Bins: Dual 25-cubic-foot (0.70 m³) micronutrient bins can be added to the twin- or four-bin system to apply up to six products at once.  Five individual gates per bin provide easy rate adjustment to achieve rates of 5-40 lbs. per acre* for your single-pass prescription application.
  • Coating: All fasteners are stainless steel where possible, or they have a 525E coating if structural hardware. Salt spray results showed standard fasteners lasted 96 hours before rusting, while those with coating lasted 1,000 hours.
