ENGINE

The perfect fusion of performance and economy.

Agrotron M tractors are equipped with turbocharged, intercooled engines with DCR (Deutz Common Rail) electronic fuel injection. Completing the class topping technology of these engines is a dual water/oil cooling system and a fuel radiator.

The two injection pumps of the DCR system, which are embedded in the cylinder block and lubricated with engine oil, and a new combustion chamber configuration in the piston contribute the extraordinary productivity of these engines even in the most demanding applications. Together with the electronic engine governor, injection pressures of up to 1 600 bar, attained irrespective of engine speed, ensure outstanding torque even at low engine speeds. The results of all this are: quieter operation at both idle and rated speed, less vibration and improved fuel economy.
For maximum eco-compatibility, DEUTZ-FAHR are B100 compatible, meaning that they can use mixtures of standard diesel and biodiesel in any proportion or even 100% biodiesel.

PTO

A PTO has never been so versatile.

Agrotron M tractors offer all four standardised PTO speed modes – specifically the two normalised speeds 540 and 1 000rpm, plus ECO modes for both. All modes are selected and engaged electrohydraulically with an automatic load sensing function to ensure that the implement connected is always started progressively and smoothly.

An automatic PTO activation function is also available, to engage or disengage the PTO in relation to the position of the implement hitched to the rear 3-point linkage. A remote PTO start button is also included as standard on the rear mudguards.

The optional 1 000rpm front PTO is driven directly by the engine via a multiplate wet clutch and is electrohydraulically engaged for progressive, smooth implement starts. The front PTO makes it possible to perform high power demand operations requiring the simultaneous use of front and rear mounted implements, saving both time and fuel.

For unparalleled PTO versatility, the output shaft is interchangeable, making potentially dangerous adaptors unnecessary.

CAB

Outstanding comfort and stability.

Agrotron M tractors are equipped with a superlative cab with an innovative suspension system offered in a choice of three configurations. The standard configuration is a cab mounted on silentblock. Otherwise is available a mechanical cab suspension system, with mechanical springs considerably reducing vibration and shock when working or driving on rough terrain, while an automatically adjusting air-sprung cab suspension system is available as an option. In the air-sprung version, compressed air is fed automatically to the pneumatic springs to keep the suspension perfectly level in relation to cab load and make full use of the suspension travel available. Larger amplitude oscillations are cancelled out quickly by two hydraulic dampers, while a Panhard bar eliminates pitch and roll of the cab module.

The compact and environmentally friendly air conditioning system includes a recirculation function and a powerful four speed fan capable of delivering an air flow of 580m3/h. The thermally insulated ducts distribute air intelligently through fourteen adjustable vents with filters located in the left and right-hand A-pillars.

Specific slits direct air towards the cab screen and windows for rapid demisting or defrosting. The controls and instrumentation are simple and intuitively laid out. All the control levers and switches are colour-coded by function.

TRANSMISSION

The ideal transmission for optimised productivity.

Agrotron M tractors are equipped with highly efficient and reliable ZF transmissions. Setting these transmissions apart are a six-speed synchromesh gearbox, a Powershift unit with four ratios per speed selectable under drive, a supercreeper gear for very low operating speeds and a hydraulic reverse shuttle. Oversized multiplate wet clutches are used to significantly reduce the clamp loads involved for each ratio, for superlative transmission reliability and durability.

The range Powershift allows rapid shifts performed under drive without stopping to eliminate time wastage. This system is enabled from a button on the transmission or from a dedicated control on the multifunction armrest.

Forty forward and reverse speeds are available, throughout an operating range at nominal engine speed from 380m/h to 50km/h (or an electronically limited top speed of 40km/h, where required by law). For maximum fuel savings, top speed is also achievable at a lower engine speed of 1 800rpm.

Ten different and intelligently spaced ratios are available in the speed range used for field applications (between approximately 3 and 10km/h), letting the driver maintain the ideal speed for any application. The powershift hydraulic shuttle lets the driver invert direction by simply using the relative lever, without pressing the brake or clutch pedals.

Direction inversions are performed rapidly and smoothly, even when manoeuvring on gradients.

HYDRAULIC SYSTEM

True efficiency means always having the right power for the job.

The hydraulic system equipping Agrotron M tractors is a permanent open centre system with an 83 litres/min gear pump feeding external applications via eight-way distributors with detent, kick-out, float and flow regulator functions.

A closed centre load sensing system is offered as an option with a 120 litres/min variable displacement pump and electrohydraulic distributors (two of which with timer function) with flow regulation.

Load sensing technology continuously alters the hydraulic power delivered in relation to effective demand to minimise energy wastage.

The load sensing system is also equipped with the Power-Beyond connection as standard, which may be used to feed implements directly with the entire delivery of the pump, without the flow passing through the auxiliary distributors of the tractor, minimising hydraulic power losses and reducing oil heating. “Push-pull” hydraulic connectors are used, for trouble-free connection of hydraulic lines even when pressurised. A specific container collects any oil which may escape when coupling the hydraulic lines of the implement.

Agrotron tractors are equipped with an efficient electronically controlled lift (with a remarkable 9 200kg load capacity) which, when connected to a radar system, may be used to operate implements with extreme precision in relation to parameters set by the operator.

The functions implemented by the electronic control system are: draft, position and mixed mode control, quick soil engagement and slippage control. The EHR system also offers quick soil engagement and slippage control functionalities.

When driving at speed on the road while carrying heavy implements, large amplitude oscillations may be produced compromising comfort and safety. To correct this phenomenon, the electronic lift of Agrotron M tractors includes an antidumping function which significantly reduces oscillation at speeds above 8km/h.

As an option, a front lift is also available, combined with a completely independent front hydraulic distributor.

BRAKES

Optimised control for every function.

The ASM system engages and disengages front wheel drive and the differential locks completely automatically, eliminating the need for repetitive manual operations which could distract the driver’s attention.

The system automatically engages and disengages front wheel drive and the differential locks under load in relation to steering angle and vehicle speed for maximum traction in all conditions.

An independent pump with a maximum capacity of 55 litres/min dedicated to the hydrostatic steering system ensures smooth, effortless steering action even in particularly challenging conditions when other hydraulic utilities are in use.

The front axle is equipped with electronically controlled suspension with two hydraulic rams. On Agrotron M tractors, the front suspension may be locked in a rigid configuration at any time for maximum precision when ploughing or using front loaders.
