DEUTZ-FAHR TRACTORS NEW ZEALAND: GERMAN ENGINEERING AT ITS BEST

5 Series

Mid horsepower perfection

The new DEUTZ FAHR 5 Series sets new standards for the mid-power class in terms of efficiency, productivity, style and comfort. The 5120|5130 models employ innovative technology to cater for any application in all possible conditions. The perfect fusion of high performance mechanical and technical solutions, unparalleled comfort and ergonomics, and eye-catching style.

The TTV version takes a step further by adding the extraordinary versatility of a continuously variable transmission. The models in this new series are more powerful and deliver more performance than their predecessors, and stand apart from their rivals with futuristic, attractive style created in collaboration with Giugiaro Design to give these extraordinary machines the elegance to match their power.

 

Engine

Compact & powerful, the 5 Series is powered by the new Deutz TCD 3.6 L04, a 3,620 cc four cylinder unit which earned the prize as best engine in its class at BAUMA 2010.

By adopting the most advanced engine technology the minimum specific fuel consumption of just 210 g/kWh - an outstanding figure for an engine of this size. To achieve these statistics the new Deutz powertrain utilises electronically controlled CommonRail injection, a turbocharger with intercooler, wastegate valve and a proportional speed viscostatic fan. 

These engines are designed specifically for agricultural applications, as demonstrated by a torque curve which remains close to maximum torque from 1,200 to 1,900 rpm - the engine speed range used in the majority of agricultural applications - and a torque reserve of more than 30%.

The engineering and design solutions adopted to maximise power and efficiency include electronically controlled common rail fuel injection, turbo-intercooler forced induction, a waste-gate valve and a proportional viscostatic fan. The electronically controlled, liquid cooled, exhaust gas recirculation system (EGR) and special diesel oxidation catalyst (DOC) catalytic converter ensure compliance with Tier 4i standards.

DOC is a special catalytic converter which catalyses chemical reactions within the exhaust gases on contact to transform them into harmless substances. DOC eliminates the drawbacks of the FAP system (which produces harmful exhaust back-pressures and necessitates energy-costly active regeneration cycles) and the SCR catalytic converter (which needs an additive such as AdBlue to trigger selective catalytic reduction), is maintenance-free and small enough for installation on compact tractors, offering the ideal solution to protect the environment. Just like its siblings with conventional transmissions, the TTV variant of the 5 Series is the ideal agricultural machine, with a practically flat torque curve offering close to maximum torque throughout a range from 1200 to 1900 rpm - the operating range used in the majority of agricultural applications. At higher engine speeds, power remains constant within the band from 1800 to 2200 rpm, for progressive, smooth operation even during jobs with very high power demands. The fully electronic engine governor delivers only the power effectively needed for the job in hand to eliminate fuel wastage.

Transmission

A modular, efficient transmission.

The configuration, offered in 5120|5130 models, consists of a synchromesh five speed, four range, 3 speed powershift gearbox with hydraulic Power Shuttle. This gives the operator a total of 60 forward and reverse speeds. The four range gearbox reduces the minimum working speed to just 134 m/h, and allowing the tractor to reach 40 km/h with the engine at economy speed. With such a large range of gears and working speeds, the 5 Series Summit is perfect for specialist roles where exact speeds are required.

The new 5 Series is also available with the TTV continuously variable transmission, which splits the power produced by the engine into two units; the majority of the power is transmitted mechanically via a planetary reduction gear unit and wet plate clutches, while the remaining smaller unit transmits power hydraulically by a load sensing pump which feeds a hydraulic motor. By varying the delivery of the hydraulic pump, the speed of the tractor can be increased or decreased smoothly, without the perceptible jerking typical of gear shifts with a conventional transmission. Coupled to a front axle with front suspension this tractor has a 50 km/h road speed.

Cabin

5 Series tractors are equipped with the extraordinary “E-Class” cab, a work environment that takes comfort and ergonomics to unparalleled new heights.
Design in collaboration between the DEUTZ-FAHR engineers and Giugiaro Design, the cab features attractive, elegant looks, employs innovative materials and is, most importantly, extremely functional. The controls are logically organised for unparalleled user-friendliness. The dimensions of the cab are optimised for outstanding all-round visibility, while an extraordinary air conditioning system with ten vents maintains the perfect environment inside the cab.
A lights control panel mounted on the A-pillar lets the driver control all the work lights and running lights installed on the tractor and on trailers and implements.
To limit vibration, the cab may be mounted on optional mechanical suspension (with steel spring and hydraulic damper) or, in the case of “P” versions only, with sophisticated air-sprung suspension.
All the controls are clearly identifiable and colour coded by function, for simple and intuitive operation of the tractor's functions. The optional Comfort-tip lets the driver store repetitive sequences of operations, which may then be recalled and executed automatically when needed. This function is particularly useful for headland manoeuvres.In addition to this information, the Work Display also provides the driver with specific tractor performance information, such as consumption figures and productivity in terms of terrain area processed.

 

 

 

Hydraulics

A complete, innovative hydraulic system.

The 5 Series is equipped with a simply outstanding hydraulic system that is extraordinarily modular and efficient.
A number of different configurations are offered. The first consists of a single pump with a maximum displacement of 60 l/min and six distributors as standard (or up to eight as an option), with mechanical oil flow regulation.
The second configuration ('ECO' option) uses a mechanically controlled dual pump (14 and 25 l/min) with flow regulator. The dual pump can already deliver maximum oil flow at very low engine speeds, for outstanding efficiency even during operations with high delivery demands but only partial engine loads.
An alternative option uses an electrohydraulically controlled dual 90 l/min pump with flow regulator, timer function and Energy Saving system.
All 5 Series models are equipped with “push-pull” hydraulic connectors, for trouble-free connection of hydraulic lines even when pressurised, and with a dedicated container for collecting any oil which may escape during coupling.
The rear lift has an impressive capacity of 4650 kg, which may be further increased to 6600 kg with the addition of two external hydraulic rams.
The EHR electronic control system enables draft force and position control, mixed control and float modes, by using a pair of load cells near the lower arms as draft sensors.
A radar system (offered as one of the optional accessories) may be used to control slippage. This function is invaluable in maximising the efficiency of a tractor in very heavy duty traction applications.
The EHR system also performs an number of other functions: quick soil engagement, oscillation damping for implements mounted on the 3-point linkage, position selectable transport lock, lift height limiter and rate of drop control.
