Description:

The Agrotron 720 uses all the latest technological solutions of the 200 hp class, with DEUTZ Common Rail engines, electronic lift with radar control, APS transmission and a hydraulic system with three independent circuits. With a compact construction and essential, eye-catching looks, this tractor is the perfect fusion between design and function. Extraordinary manoeuvrable and remarkably user-friendly, the Agrotron 720 is the definitive state of the art tractor.

Engine:

Powerful, reliable engines packed with high technology. 
The Agrotron 720 is powered by potent 7146 cm³ six cylinder DEUTZ TCD 2013 L06 engines. The four valve per cylinder head ensures perfect combustion chamber filling, and makes it possible to locate the injector vertically and precisely in the centre of the head, for maximised power and fuel efficiency perfect. The Agrotron 720 is bristling with state of the technological solutions: turbocharger and intercooler with dual water/oil cooling circuits; AGRex external exhaust gas recirculation system, which recirculates precisely measured quantities of cooled exhaust gas back into the combustion chamber to minimise nitrogen oxide emissions (NOx); DCR (Deutz Common Rail) electronically controlled high pressure injection system, with two injection pumps embedded in the cylinder block and lubricated with engine oil. All of these features work in concert to ensure extraordinarily high and consistent productivity, even in the most challenging applications. The DCR system delivers injection pressures of up to 1600 bar independently of engine speed which, together with the electronic engine governor, ensures an outstanding torque reserve even at low engine speeds. This system significantly reduces noise at both idle and rated speeds, increases peak torque and minimises vibration, but with no increase in fuel consumption.

Hydraulic System:

Three independent hydraulic circuits for unrivalled productivity.

The hydraulic system of the Agrotron 720 series consists of not one but three different circuits. The first circuit provides lubrication oil to the transmission and hydraulic power for a number of functions and systems such as the Powershift, the hydraulic reverse shuttle, PTO engagement and front wheel drive and differential lock management.
A second, completely independent circuit feeds the hydrostatic power steering system, while a third closed-centre circuit with a 120 l/min load sensing pump feeds the lift and the distributors.
The latter system has four dual action auxiliary distributors (for a total of eight ways) with flow regulator function. The control levers are colour-coded in relation to the respective hydraulic connections and may be locked in “delivery” and “float” modes. 
Agrotron 720 tractors are equipped with a lift controlled by the electronic EHR system, which performs a number of functions: draft force and position control, mixed control mode, slippage control, quick soil engagement, float mode, oscillation damping, transport lock, implement lift height limiter and rate of drop control. The maximum load capacity of the lift at the quick hitches is an impressive 10,500 kg – among the highest in this class.
When driving at speed on the road while carrying very heavy implements, large amplitude oscillations may be produced compromising comfort and safety. To correct this phenomenon, the EHR system includes an antidumping function which minimises oscillation at speeds above 8 km/h. 
The Power-Beyond coupling bypasses the entire pressurised oil flow of the system to a hydraulic motor installed on the mounted implement, for connecting implements with their own hydraulic units. 
The rear lift has its own dedicated external oil tank, to prevent the possibility of gearbox lubrication oil accidentally coming into contact with hydraulic transmission oil. This solution maximises the safety and efficiency of the hydraulic system by reducing oil heating and eliminating entirely the remote risk of emulsification.
