Key_features
| The front axle, produced at the Argo Tractors plant facilities, features a standard limited slip differential lock with electro-hydraulic four-wheel drive. Furthermore, it guarantees high efficiency when using front coupling equipment, which can be directly installed on the support element or, as an option, be moved using the front coupling lifting device fully built-in with the chassis and the front PTO. The extensive axle oscillation, combined with the 55-degree steering angle, makes the models exceptionally easy to handle. The availability of a chassis custom designed for mid-mounted applications further enhances the versatility of the REX4 range. Thanks to suitable maintenance and the use of quality oils, it has been possible to extend the engine maintenance intervals, doubling service hours from 500 to 1,000, with a marked reduction in maintenance costs and machine downtimes. A new panel has been developed for the platform version to make accessing the clutch and adjusting the reverse shuttle control even easier. |

 New generation Deutz engines
The line-up includes REX 4-080, 4-090, 4-100, 4-110, 4-120 models with outputs ranging from a minimum of 75 Hp to a maximum of 112 Hp. This is thanks to the new generation Deutz engines featuring 4 cylinders and 16 valves, 2.9 litres, Common Rail electronic injection Turbo Intercooler, which guarantee a boost in performance in terms of torque reserve, increased power and lower fuel consumption. As seen on the previous models, the Engine Memo Switch, which stores and swiftly recalls the most suitable engine speed, is also fitted on these versions to accelerate one’s work.

 Two possible configurations for transmission
The transmission options range from the 12 Forward + 12 Reverse Speed Four gears with mechanical reverse shuttle, to the 48 Forward + 16 Reverse Robo-Shift version with electro-hydraulic reverse shuttle and with fully robotised HML. This is easily controllable by means of an ergonomic and user-friendly joystick that manages all the controls required during operations.

 Hydraulic circuit
The versatility of the REX4 models is guaranteed by the open centre hydraulic circuit, equipped with a 30 litre per minute steering pump for easy manoeuvring (even during processing operations), plus a 58 litre per minute service management pump. A third tandem pump connected to the services pump is also available, which makes it possible to achieve a flow rate of 55 litres per minute at just 1,500 rpm. A total of 4 rear and 3 mid-mounted spool valves can be added to the standard equipment, where a fully electro-hydraulic configuration is also available. The platform models (GE, GB, F and GT) feature an electronic rear lifting device with a maximum capacity of 2,700 Kg, which can be further increased to 3,200 Kg for the GT version, making it the highest performing tractor in its segment. |
