Fendt 800 Vario makes the working day a pleasure

Large tractors in the power class of up to 350 hp are mainly used by contractors and on large arable farms. The Fendt 800 Vario Gen5 series is a completely newly developed machine and covers a performance range of up to 343 hp with three models and the Fendt DynamicPerformance added power concept. For the first time, the series will receive technologies such as VarioDrive, the low-speed Fendt iD concept and the self-cleaning engine air filter. The new cab and innovative lighting concept increase work comfort throughout the working day.

The fifth generation of the 800 Vario, with three models (Fendt 826, 829 and Fendt 832 Vario), sits at the power range from 260 to 320 hp (191 – 235 kW) in the Power+, Profi and Profi+ versions. The completely new developed series has the Fendt DynamicPerformance (DP) added power concept is available for all models and additionally releases 23 hp (17 kW) each when its required due to secondary consumers such as the cooling fan, oil pump or air-conditioning compressor. Under all operating conditions, the machine will always provides enough power for the main consumers such as the travel drive which increases productivity.

Designed to meet the requirements of contractors and large agricultural farms worldwide, the focus of the new development was on a powerful and manoeuvrable overall package with a high payload, low fuel consumption in various conditions and comfortable operations. The Fendt VarioDrive, the latest generation of the Vario transmission paired with the efficient 6-cylinder CORE80 engine with 8.0 litres cubic capacity, specially developed for Fendt, is pivotal for the low fuel consumption. Exhaust gas after-treatment takes place via a diesel oxidation catalytic converter (DOC), diesel particulate filter (DPF) and with selective catalytic reduction (SCR) without exhaust gas recirculation. It meets all the emission standards required worldwide. In the EU, this is the emission standard Stage V.

The CORE80 engine is already approved for HVO100 and other fuels according to DIN 15940. Operating with HVO can significantly reduce the machine's CO2 footprint. There are also maintenance-free hydraulic tappets built into the engine. The first engine oil service occurs at 500 h, so the initial 50 h interval has been omitted. Technical optimisations increase the replacement interval of the transmission oil from 2,000 to 4,000 operating hours or 4 years. This further reduces maintenance costs.




Manoeuvrable thanks to Fendt VarioDrive
The single-stage Fendt VarioDrive drivetrain with permanent, independent four-wheel drive was first introduced in 2014 with the Fendt 1000 Vario and is now available for the first time in the Fendt 800 Vario series. This enables maximum tractive power with high soil protection on different subsoils. In addition, there is no need for manual shifting when switching between field and road. VarioDrive drives the front and rear axles independently of each other and distributes the power dynamically. Another advantage is the so-called pull-in turn effect. Thanks to the pull-in turn, the independently driven front axle actively pulls the machine into the turn without torsion and the Fendt 800 Vario achieves a particularly small turning circle.

Fendt iD low-speed concept saves fuel
All tractor components such as engine, transmission, hydraulics and cooling were now designed for the so-called “high torque – low engine speed” principle. The Fendt iD low-speed concept allows the Fendt 800 Vario to achieve high torque and saves fuel at low engine speeds. The rated engine speed is only 1,700 rpm. In the main working range, the speed is a quiet 1,100 to 1,400 rpm. The speed of 40 km/h is reached at 950 rpm, 50 km/h at 1,200 rpm, and the top speed of 60 km/h at 1,450 rpm. The maximum torque of 1,680 Nm is available on the top model Fendt 832 Vario from 1,200 rpm and ensures high tractive power and acceleration with minimal specific fuel consumption.

High payload for teams
The payload of a tractor decides which implement combinations are possible with the tractor. The low operating weight of 9.9 t with a permissible overall weight of up to 17.5 t with an approval for 40 and 50 km/h results in a payload of 7.6 t. This enables legal work in the team with a precision seed drill with a front tank or the legal transport of a front-rear mower combination. In addition, there are flexible options for ballasting at the front and on the rear wheels so that the machine runs optimally in field or road use.

Brings light into the darkness with up to 114,700 lumens
The tractor cab is central to driving comfort: the seat, air-conditioning, lighting and viewing angles influence the working comfort and the result of the work. With the Fendt 800 Vario series, Fendt is presenting the new tractor cab with exclusively developed lighting concept for the first time. Work such as sowing, harvesting, pesticides or winter service are highly dependent on the weather. For example, if the work lasts until night due to a threatening weather swing, the tractor's lighting can decide whether the work can continue.

Easy and fast operation
Up to four individual profiles can be stored for convenient and quick operation of the work lights. For example, if the tractor is driving to the left of the field chopper, the driver can dim the light on the side of the chopper, while brightly illuminating the rest of the environment so as not to glare the chopper. The configuration can also be mirrored with one click. This function is helpful when the chopper driver is driving along side the forage harvester. Also new is the independent control of the individual spotlights. If the weather changes due to fog or rain, the light intensity can be adjusted quickly.




Efficient ventilation, cooling and filtration
As standard, the Fendt 800 Vario is now also equipped with the exclusive Concentric Air System (CAS) ventilation & cooling concept. The fan can be optionally equipped with a reverse function. In addition, a self-cleaning air filter including automatic control is optionally available for the CORE80 engine. If the engine air filter is cleaned automatically, drivers can carry out their field work without interruption, and regular cleaning increases the longevity of the machine and ensures optimum fuel consumption. This DLG awarded system is already known from the Fendt 1000 Vario. Now this option is always offered together with the automatic dust extraction for the cab air filter. In this system, the cab air filter is continuously and automatically passively cleaned by vacuum and a cyclone separator. This function has been specially developed for use in hot or particularly dusty conditions, such as cultivators in dry weather. It reduces daily maintenance and increases the air quality in the cab.

High hydraulic power for use with complex implements
Complex implements such as precision seed drills with integrated fertiliser tanks and high separation rates place high demands on the hydraulic system of a tractor. The Fendt 800 Vario now has a maximum of six hydraulic control units in the rear and two in the front (6+2). A maximum of 4 control units in the Power+ equipment line are available in the rear and one in the front (4+1) or five control units in the rear (5+0). Customers can also choose between three hydraulic pumps: 165 l/min, 220 l/min and for consumers with varying requirements in terms of oil quantity and pressure, a double pump system with a maximum flow capacity of 385 l/min (165 + 220 l/min) is available. If the implement transfers a particularly high amount of heat into the hydraulic system or if the tractor is used in hot regions, an optional additional hydraulic oil cooler improves the hydraulic oil cooling capacity. In the rear, the optional FFC flat-sealing couplings for control units and the Power Beyond connection prevent the dirt ingress into the system as well as leakage oil and reduce pressure losses. The relieving rear power lift transfers weight from the implement to the tractor for optimum ground hugging, for example when working with milling machines or mulchers. The lift assist for the top link takes over part of the weight from the top link and supports the work ergonomics when mounting implements.

Transportation talent at up to 60 km/h
The Fendt 800 Vario achieves a high overall productivity thanks to its versatility. Features such as VarioDrive, top speed of up to 60 km/h, the high payload, the comprehensive chassis and safety concept, the optional exhaust brake in conjunction with the hydraulic auxiliary brake, the self-centring Fendt Reaction Steering, Fendt Stability Control (FSC) or the Trailer Brake Assistant (TBA) characterise the series in transport. The trailer brake assistant displays its advantages, for example, in the team with an attached sprayer or a pneumatically braked trailer in the chopping chain. Then this keeps the team in line even in curves on the slope and prevents it from jack-knifing or drifting. The optional automatic parking brake and numerous axle and tyre options round out the package.

For large areas in grassland
On large grassland areas, farmers and contractors need powerful technology with a high payload that works in a soil-friendly manner. They use suitable time windows efficiently even in unsafe weather conditions. Complex mowers combinations, such as a Fendt Slicer front mower and Fendt Slicer 1010 RCB PRO rear mower with conveyor belt, require sufficient payload to legally transport the mowers. The low empty weight of the machine, the optionally cooled front PTO, the Fendt VarioGrip tyre pressure regulation system and the full range of FendtONE onboard characterise the Fendt 800 Vario in grassland use. While the independent four-wheel drive from Fendt VarioDrive protects the sward and avoids forage contamination, Fendt VarioGrip reduces ground pressure. In addition, a position control and relief control for the front power lift is optionally available for the Fendt 800 Vario. For an optimal cutting pattern, the cutter bar is guided permanently with a constant pressure, regardless of the ground contour. Options such as GroundVision drawbar lighting or the LSG front window increase safety.

Numerous axle and tyre options
For the Fendt 800 Vario series, there are numerous options for track width, tyres and the Fendt VarioGrip tyre pressure regulation system. Depending on the local requirements, customers can now order the tractor as standard with a flange or a stub axis (3.0 m or 2.50 m). The 2.50 m stub axis is now also approved for 60 km/h and is the basis for the optional dual wheel hub. The dual wheel hub is a coupling system for dual wheels that allows the transfer of higher forces. The dual wheel hub transmits the power safely through the axles instead of the rims as in other systems. The track width of the dual wheels is adjusted in the 2.5 m version via flexible intermediate pieces (spacers).




New: Guidance system at up to 40 km/h
The speed of the team can be a limiting factor in use with implements such as a fertiliser spreader or a pesticide sprayer. Until now, the use of a guidance system was limited to a top speed of 25 km/h. With the Fendt 800 Vario series, Fendt offers a new guidance system option: Fendt HighSpeed Guidance. This is a further development of the classic guidance system, which can be used at up to 40 km/h in agricultural areas. It is particularly interesting for farms with large and predominantly flat structures, such as in North or South America, as well as in Australia, which carry out pesticide and fertilisation measures at high speeds. In Europe, the areas are often structured smaller, and here, too, speeds above 25 km/h can make an important contribution to time-critical field processing in tight time windows.
