REX4 F-S-V-GT,benchmark for specialist tractors around the world

The REX4 is equipped with the state-of-the-art generation of Deutz-AG TCD Stage V, 2.9-litre, 4-cylinder engines from 75 to 112 HP, Turbo intercooler and Common Rail electronic injection. With a maximum power of between 1,500 and 2,000 rpm, these engines are outstandingly efficient: they deliver higher power, cut fuel consumption and offer greater versatility in use. The fuel tank capacity is 65 or 85 l, depending on the version. The fuel consumption is reduced to a minimum thanks to the passive generation of exhaust gas and the presence of the Engine Memo Switch, a device which allows the operator to store and recall the engine speed most suited to the implement used.

The REX4 is equipped with a Speed Four transmission: 4 synchro nised gears and 3 mechanical speed ranges, for a total of 12 FW + 12 RV. With the Creeper it reaches 16 FW + 16 RV. The Speed Four transmission is modular, so it can be customised with the following options:

- Power Four: 2 gears under High-Low load, 24 FW + 24 RV; with the Creeper: 32 FW + 32 RV.

- T-Tronic: 3 gears under High-Medium-Low load, 36 FW + 12 RV; with the Creeper: 48 FW + 16 RV.

- RoboShift: robotised gearbox, 36 FW + 12 RV; with the Creeper: 48 FW + 16 RV, for maximum comfort.

The RoboShift transmission has a power-assisted gearbox on both the 3-gear H-M-L load and the Speed Four driving 4-gear versions. RoboShift is the transmission with the most advantages:

More Comfort: the RoboShift robotised gearbox is managed by the simple and practical multi-function joystick, providing extra Comfort.

More productivity: the RoboShift electronic gearbox allows the operators to choose between the extreme simplicity of working in manual mode, which allows them to manage the gearbox with two buttons, and the extreme comfort of working in automatic mode, which automatically identifies the best gear speed, leaving the operators free to concentrate on the work, to the advantage of productivity.

The Lounge Cab is a true mobile office where working becomes fun. Its 4-post structure guarantees 360° all-round visibility. In addition, easy access thanks to the hinged doors at the rear, the clear flat-deck platform, adjustable operator driving seat, ergonomic controls, automotive inspired materials and air condi tioning make this cab a perfect working environment whatever the season. On the F and GT models, the outer cab width is 1,205 mm, whilst on the S and V models it is 1,000 mm.
The interior of the REX4 Lounge Cab is inspired by the automotive industry to offer the operator a more comfortable driving and working environment. Here you have everything under control and within reach. The digital instrument panel keeps you constantly informed on the tractor performance; the telescopic tilt-adjustable steering column is designed to tilt with the dashboard; the driver’s air suspension seat provides maximum seating comfort; the joystick and all control levers and pedals are ergonomically posi tioned for maximum ease of operation. These qualities guarantee greater comfort for the operator and better control of the work, resulting in increased productivity.

The REX4 Lounge Cab is suspended on Hydro-Silent Blocks. The F and GT models can be equipped with mechanical spring-loaded shock absorbers, with a vertical travel of up to 60 mm. On the F, S and GT models, the front axle can be suspended: vibration-proof solutions for a more comfortable working environment. Because Landini is well aware that more comfort means more productivity.

The new REX4 hydraulic system is more flexible than ever before, to guarantee each and every farmer tailored solutions that meet their individual requirements. The standard hydraulic system features a double pump that sup plies 58 + 30 l/min to the rear hitch and the spool valves, and 30 l/min to the steering system. An optional 30 + 58 + 36 l/min triple pump is also available on request: the first two pumps are dedicated to the rear hitch and the rear and mid-mount spool valves and, by combining the flow rates, they reach a maximum capacity of 88 l/min, of which 54 l/min are already available at an engine speed of just 1,500 rpm; the third pump is independent and serves the steering circuit. The hydraulic circuit configuration allows the use of up to 7 spool valves, 4 of which are mechanical or electro-hydraulic rear valves and 3 electro-hydraulic mid-mount valves. The REX4 can also be equipped with either a flow selector, with a diverter with 4 or 6 outputs, to control multiple elements with a single control system, or a flow diverter valve, to regulate the oil flow in the spool valves. In addition, it can also be equipped with hydraulic stabilisers, top link and right rod: 2 simple but tons manage their movements, for attaching implements or for adjustments during row-crop work.
