New Holland's Tier 4 Final Lineup

10/02/2013 @ 2:16pm

New Holland launches T7, T8, and T9 Tier 4 Final compliant tractors with ECOBlue Hi-eSCR technology. “The ECOBlue Hi-eSCR solution delivers consistency, performance, simplicity, and efficiency,” says Abe Hughes, New Holland.

The ECOBlue Hi-eSCR system is an evolution of the existing ECOBlue SCR system, developed by New Holland’s sister company FPT Industrial. The new Engine Control Unit manages the engine and the after treatment system by controlling the supply and dosing modules. Using a dedicated closed loop system, it continuously monitors the NOx levels in the exhaust gases, ensuring that during every cycle the precise amount of DEF is injected to achieve the necessary NOx conversion of 95%.

The key new components of FPT Industrial’s system are:

  • Patented closed loop system. Using additional sensors located at the exhaust outlet of the engine, precise NOx levels are recorded for the exact DEF dosing. This enables the neutralization of even more NOx, without excessive DEF consumption.
  • Engine exhaust flap ensures the engine always operates at its optimum temperature.
  • Diesel Oxidizaiton Catalyst oxidizes the exhaust gas, guaranteeing the optimal mix between nitrogen oxide and nitrogen dioxide, increasing the conversion efficiency in the SCR catalyst.
  • Clean up catalyst removes excess ammonia.

ECOBlue Hi-eSGR technology offers four key benefits:

  • Performance: the productivity increases enjoyed at Tier 4 interim, in terms of power, torque, torque back-up, transient response, and engine power management, will be maintained at Tier 4 Final.
  • Efficient operation: the fluid consumption will be the same or better than Tier 4 interim machines. There will be reduced operating costs, including longer 600-hour service intervals.
  • Simplicity: the simplified engine installation ensures a higher power potential, and the reduced cooling system delivers more efficient operation.
  • Consistency: ECOBlue SCR technology will continue to be used at Tier 4 Final so you won’t experience a change in vehicle operation.

T7 Increases Power and Automation
The 2014 T7 range has three standard wheelbase models between 140 to 165 hp. and four long wheelbase models from 180 to 240 hp. New features include a headland turn sequence function, which allows complex end of row operations to be recorded, edited, and stored. The CommandGrip multifunction handle can be configured to operate any of the electro hydraulic remote valves. Future tractor automation will come with the new ISOBUS Level 3 compatibility; this means that an implement of a similar level will be able to take control of some key functions on the tractor.

T8 Adds Power
The five Tier 4 Final T8 tractors range between 320 to 435 maximum engine power management (EPM) hp. on tap. The tractors benefit from up to an 8% higher EPM band of 56 hp. to further improve performance when working with large implements. Key new product features include a HID lighting package.

T9 Refines Operating Performance
The T9 range tops out with the T9.700 at 699 maximum engine horsepower. Operating performance has been refined with enhanced steering accuracy thanks to improvements to the Terralock automatic differential locking technology. Shuttling times have been reduced to facilitate fast direction changes.
