Model T9390 - Tractors


T9 engines make use of Selective Catalytic Reduction (SCR) technology and DEF/AdBlue® after treatment to convert the nitrogen oxides in exhaust gas into harmless water and nitrogen. This treatment is separate from the air intake which means an SCR engine “breathes” only clean fresh air, ensuring optimal combustion conditions. New Holland has the advantage of working with an experienced engine development partner, Fiat Powertrain Technologies (FPT).Since FPT has already produced over 100,000 SCR engines during the past five years for trucking and agricultural use, you can be assured of T9 engine reliability.


The Cursor 13 engines used in the two largest models, the T9.615 and T9.670, use a two-stage turbocharger. The first turbo feeds the second, delivering higher torque and higher sustained power to cope with the most demanding tasks and conditions.


The T9 cooling system features improvements compared to previous models to handle the heat generated by the new, more powerful engines. The new, improved flow of cooling air travels through venting in the new grill, over the new radiators and over the engine.


Engine braking is activated automatically when you release the throttle when transporting. It uses the compression of exhaust gas to slow the T9 tractor down, saving wear on the brake pads. Just step on the convenient floor pedal and the exhaust is restricted from leaving the valve and is compressed by the piston moving upwards. This compression of exhaust gas slows the tractor down.
