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

 

5G Series

 

 

The latest addition to the Deutz-Fahr mid HP sector is the 5105.4G Vista and 5115.4G Vista. These two new models complete the current 5 series product offering of 5120, 5130 Summit and TTV specification tractors. Both of these new tractors feature the latest Tier 4, 4.0 litre FarMotion engine. 

The 5 G series are Modern, stylish machines, designed to give maximum working versatility, with flexible specification options to satisfy the requirements of the most demanding customers. In addition, its unique features enables the 5G Series to guarantee an unrivalled level of safety under any work conditions.

Engine

The new FARMotion Tier 4i engine employs the latest technology to ensure performance that is reliable and long-lasting. The FARMotion engine is available as a three or four cylinder variant. The engine is built using many well-known components including a Bosch injection system for its common rail technology. The motor utilises a turbo charger, intercooler and electronic control to develop its fantastic torque characteristics.

This new engine meets emissions compliance through the use of Exhaust gas recirculation (EGR) and a diesel oxidation catalyst (DOC). The major benefit to this emissions system is the lack of Particulate filters and or ad-blue meaning the owner has no ongoing or future operating costs. The FarMotion engine has been designed and developed by SDF for exclusive agricultural use. The core focus in the design and development of this engine was to produce a motor with low noise, better engine performance, lower fuel consumption and less vibration. The FarMotion engine is the successful result of this design.   

The fuel supply system uses new, 7-hole injectors and Common Rail technology with maximum operative pressures of up to 2000 bar. This maximises the immediate response to sudden load variations and at the same time decreases emmissions pollutants. Highly flexible and with torque reserve values of 30-35% depending on the version, the FARMotion engine is well suited to the new 5 series range.

The new, sturdier FARMotion engines use cylinders with thicker, extractable liners (to simultaneously increase resistance to cavitation erosion and reduce noise and vibrations) and a new, forged steel crank shaft to make them more robust and give improved balance. The new engine block has been strengthened for increased reliability and durability; this is appreciated most when the tractor is fitted with a front loader.

Regular maintenance of the FARMotion is now very easy, thanks to the single, multi-purpose belt with automatic tensioner (which requires no manual adjustment).

 

The new engine has been meticulously designed with an electronically cooled and regulated, external EGR linked only to the DOC (Diesel Oxidation Catalyst),i.e. a simple Diesel engine catalyst, to comply with the emissions standards.

This is not a diesel particulate filter, generating potentially high counter-pressures on the exhaust gases, which requires regular time-consuming cleaning cycles. Nor is it a selective catalyst reduction device such as SCR which requires the use of an additional agent AdBlue. This therefore means that the tractor will operate day in day out without additonal ongoing running costs to manage the tractors emmissions system. 

Transmission

5-gear versions, up to 4 work ranges (slow, fast, underdrive and supercreep), 2- or 3-gear Powershift, hydraulic shuttle: the wide variety of options allows almost unlimited variations, capable of fulfilling all your work speed requirements. In practice:from 40 to 60 speed gears for each direction of travel and the possibility of travelling at 40 km/h with the engine in economy drive.

A press of the button on the gear lever and without using the clutch pedal, the Hi-Lo can reduce (or increase) the gear speed when loaded by approximately 16%. This option is particularly useful when working on a very uneven terrain. A 3-speed Powershift uses the same method to further decrease the transmission ratio which helps when transporting heavy loads and encountering road inclines. To facilitate quick, repetitive operations, the shuttle lever is located in an ergonomic position to the left of the steering wheel. 

Shuttle control is hydraulically adjusted with a 5-position modulation control; this option is useful in terms of productivity and safety, especially if the machine frequently operates in a restricted area with a front loader. In addition, the hydraulic shuttle is equipped with two sets of multi-disc, oil-immersed “Long life” clutches to reverse up to 13 km/h, even when loaded. The GS versions also have the Stop&Go, which allows you to stop and restart the tractor without having to use the clutch pedal. The tractors electronic management system allows the brake pedal to in effect become an inching pedal with speed control. This particular feature makes the 5 series an unbelievably user friendly front end loader tractor  

The PTO on the 5G Series has 4 standard speeds (540/540ECO/1000/1000ECO), with electrohydraulic engagement. An optional front PTO which operates at the standard 1000 rpm can be fitted with the front hitch.

The PTO is simple and logical to handle, thanks to the electro-hydraulic controls on the right-hand console and on the rear fenders. The engine revs are shown on the instrument panel which moves with the steering wheel adjustment to ensure clear unobstructed view of the operating speeds.

In the versions with an electronically controlled hitch, the Auto PTO function allows you to automatically stop and start the rear PTO in conjunction with raising or lowering the rear linkage.

Cabin

The 4-post cab provides excellent visibility under all working conditions and guarantees a functional work environment with superior comfort and well laid-out controls. All Deutz-Fahr tractors utilize a colour coded operating system. An array of colours for each button or lever represent their purpose. Ie: blue denotes the auxillary spool valves, green denotes the rear linkage whilst yellow represents any association to the PTO. This method of colour coding streches throughout the entire Deutz-Fahr range making it simple for an operator to come to terms with an operating platform when going from model to model

The carefully designed space, eye-catching contours, innovative materials, passenger seat and ergonomic layout of the controls, divided into a logical “colour-coded” sequence, all put the 5G Series cab at the top of its class.

Up to 8 work lights (6 on the cab roof and 2 mid mounted on the cab corner posts) allow you to illuminate your entire work area at night.

The standard rear LED warning lights ensure maximum on-road visibility. Lastly, the back-lit instrument panel and side console allow the operator to clearly identify each individual control.

Hydraulic System

The 5G Series offers efficient, modular hydraulic systems. The standard open centre system has a 55 l/min pump, with a maximum of 4 (one of which is electronically controlled) rear auxiliary valves.

The SDD, a dual tandem pump is the latest innovative hydraulic feature which you can switch on and off with a button on the steering column. It allows you to turn the wheels completely at slow speed lock to lock with only 2.2 turns of the steering wheel. This increases productivity for manoeuvres on tight headlands or when working with a front loader in a restricted area.

The linkage position and lift of the standard rear hitch is the Electronic Hitch response control (EHR). The hitch not only offers a draft/position mix function, it can also perform rapid soil engagement (float position), dampening of oscillations (ride control)during the transport of the implements carried by the 3-point hitch, lift height limiter and adjustable lowering speed control. It has a maximum rear lift capacity of up to 4800 kg (5400 kg for the 5115.4 G model), with a front lift capacity of 1850 kg
