Evidently, over the past decade, the energy requirement for performing basic tillage operations has significantly increased. Not only is greater tractive and hydraulic power needed, but also higher transport speeds and a higher level of operator comfort are essential.
Meet the new medium-to-high power class tractors, the Fendt 800 Vario.TMS“.
The new Fendt 800 VarioTMS – a class-leading tractor
„Fendt 819-828 VarioTMS“– the latest series of Fendt tractors, covering a power range from 200 to 290 hp.
In constructing these models, the needs of leading, innovative farms have been taken into account. Thus, tractor structural elements have been adopted (for example, the stepless, split-power transmission „Fendt Vario ML200“ has been used in the previous generation „Fendt 900 Vario").TMS“series tractors) or designed with the requirements of high-power tractors in mind. Based on the overall dimensions, wheelbase, the new „Fendt 800 VarioTMS“series tractors occupy an intermediate niche between the mid-range tractors of the Fendt 818-820 VarioTMS“and its high-power Fendt 922-936 Vario classTMS“tractors. This positively impacts the tractor's manoeuvrability, and its construction features a particularly high load factor of 1.7 (which is the ratio between the overall weight of the tractor, fully loaded with ballast weights and implements, and its structural weight).
When compared with the production Fendt 818-820 VarioTMS“The new tractors are structurally entirely new machines.
The most modern management system in its class
Externally, the new tractors resemble those of the high-power class. 900 VarioTMS. Used a similar, extremely spacious 5.5m cabin designed by the Porsche Design Studio2 A cab with glazing area and a door only on the left side, version X5. It is connected to the tractor chassis via an independent pneumatic suspension system. Optionally, the „Fendt Evolution Active“ driver's seat with active pneumatic suspension can be fitted. This Grammer seat is considered not only the most advanced but also the most effective currently available on the market.
The control devices are also analogous to the company's flagship, with the exception of the new generation Variable Control terminal and considerably expanded control functions. Depending on the equipment Variable The terminals can be 7 or 10.4 inches diagonally. The latter display is the largest on the market. The largest screen allows simultaneous viewing of camera, navigation, and tractor system displays. This screen is particularly effective when working with implements whose control system is connected to the tractor via ISO-Bus line.
The most powerful, fuel-efficient engine in its class
Semi-frame construction tractors are fitted with 6-cylinder, 6.06-litre turbocharged Deutz 2012 series engines with a new generation Bosch EDC 17 control processor. Instead of an external EGR (Exhaust Gas Recirculation) system.Rex), engines are equipped with selective catalytic reduction catalysts SCR, using a 32.5% urea water solution AdBlue. This catalyst allowed for a record reduction in fuel consumption to 192 g/kW.h.
Selective catalytic reduction (SCR) catalyst is one of the most effective means of reducing nitrogen oxide (NOx) emissions from exhaust gases. Therefore, new engines comply with the transitional Stage IIIB/Tier 3 emission requirements. The „Deutz 2012“ can be used with 100% RME fuel without modification.
Engine power system – accumulator system with extremely high pressure, first for tractor engines up to 2000 bar, common rail In new engines, two-stage fuel injection has been implemented. Therefore, the engine runs quietly and economically.
In the engine cooling system, as in the Fendt 900 VarioTMS“in the series, an electrically controlled viscous fan clutch is used Viscotronic. It allows for extremely precise adjustment of the fan speed, depending on the engine load and thermal conditions.
The most efficient stepless gearbox on the market, Vario
New 800 VarioTMS A stepless split power flow gearbox, the Fendt Vario ML200, with overload protection is used in the series. Turboclutch. This protection, much like a hydraulic clutch in the past, not only safeguards the power unit and transmission from overloads, stabilises crankshaft oscillations, and reduces driving wheel slippage, but also extends the lifespan of the engine and transmission by up to twofold. The tractors are equipped with a new design rear axle, the „Fendt HA220“, featuring an efficient pressure lubrication system that results in lower power losses in the transmission. The maximum tractor speed of 60 km/h can be achieved at an economical 1700 rpm.-1 engine revs. 50 km/h speed is reached at 1450 rpm-1 engine revs. The tractor's minimum programmable speed is 20 m/h.
A powerful hydraulic system will fit any equipment
The hydraulic system, as is standard for Fendt tractors, is completely separate from the transmission, allowing the use of bio-oils. The variable displacement, closed-centre load-sensing (CCLS) hydraulic system can be equipped with axial piston pumps of three different capacities: 109, 152 or 193 l/min. The hydraulic system capacity is 80 l. Up to 6 pairs of hydraulic couplings can be fitted at the rear of the tractor, and up to 2 pairs at the front.
The priority steering system is equipped with a separate pump with a flow rate of 48 l/min. Therefore, steering efficiency is not compromised even when engine speeds are significantly reduced.
Traditionally, for Fendt tractors, the front electro-hydraulic linkage is integrated into the chassis structure. The hydraulic cylinders on the rear and front linkages are, depending on the equipment, double-acting. A fully autonomous position control system for the front linkage can also be fitted as an option.
For the first time, Fendt tractors are offered in three equipment levels: Power, Profi, and Profi Plus. The base Power equipment level already includes hydropneumatic front axle suspension, an independent air-sprung cabin suspension system, an air-sprung driver's seat, air conditioning, and a 7„ diagonal Variable terminals, adaptive engine and transmission control system TMS, allowing selection of the most economical operating strategy, 4 pairs of hydraulic couplings at the rear, two-speed (540 E/1000 rpm-1rear GTV, 50 km/h speed.
Profi The equipment also includes a dynamic stability control system FSC (stabilising the front axle's travel) and a command sequence end-of-field program. Variotronic TI, ISO-Bus Aggregate control line, front electro-hydraulic hitch, double-acting rear hitch hydraulic cylinders, 2-circuit hydraulic tractor brake system, 60 km/h speed.
Additionally Profi Plus in the equipment – 10.4″ diagonal Variable Terminals, precision farming, work accounting software VarioDoc on a remote data transmission protocol Bluetooth.
