A robust and compact machine
The Mechanical Boxer 4 x 2 comes equipped with an MWM 4.10 TCA engine and features an EGR exhaust gas recirculation system to reduce emissions of nitrous oxides. With 4 cylinders of 4.3 liters, it uses an aftercooler system and 92.6-kW output at 2200 rpm. The configuration of the self-propelled sprayer engine meets MAR-I pollutant emission standards and is approved to work with B10 Biodiesel (up to 10% in the mixture). Among the features of the 10 series are individual cylinder heads, wet cylinder liners, ribbed connecting rods and components such as water and oil pumps, in addition to the oil cooler built into the engine block.
Ultra-resistant frame and axles
Designed in a single structure, the frame of the Mechanical Boxer self-propelled sprayer is formed by tubular steel beams, joined by high-strength welding metals and several reinforcement points to improve safety and durability on uneven terrain. Its low weight also favors less soil compaction. The axles and legs are also reinforced to withstand the most diverse operating conditions, terrain, drive and steering systems, as well as making the connection between the tires and the frame. In addition, the Mechanical Boxer 4 x 2 has a 2.5 meter fixed track width adjustment axis.
Transmission and differential
The Mechanical Boxer has a 4 x 2 mechanical gearbox, with 5 forward speeds and one reverse. The transmission in the rear wheel hub is performed by an oil-bathed tensioned chain. The differential, in turn, offsets the distance travelled between the two wheels of the same axle during a curve, which is a very important characteristic because the inner wheel would otherwise slip on the curve. The differential lock, on the other hand, equalizes the torque for both axles, enabling the wheel in contact with the ground to also turn and move the vehicle. In addition, it is equipped with the “Limited Slip Differential - LSD” system, which allows output shafts to rotate at different speeds while limiting the maximum difference between them.
Boxer M brake systems
The Mechanical Boxer 4 x 2 self-propelled sprayer has disc service brakes on all four wheels. On them, a pair of pads, under hydraulic pressure action, tightens both sides of the disc connected to the wheel, making it stop as friction is applied. It’s a very efficient system. In addition, it has a stationary brake that is actuated by means of a button just behind the gearbox, right next to the operator. Its main purpose is to keep the vehicle stationary when it is already at a standstill, whether the engine is running or not, by braking the rear wheels. When engaged, the service brake is unnecessary.
The Boxer self-propelled sprayer comes equipped with the Isoview display: technology featuring an easy-to-use intuitive interface, which starts a job in just three clicks, bringing intelligence to production without increasing complexity. This onboard controller comes with integrated GPS and autopilot to guide the operator, making it possible to significantly reduce the amount of inputs, avoiding overlap during application. In addition, Isoview controls the spraying and the 7 sections, working with terrain compensation and electronic sensors to prevent deviations due to unevenness, holes or ditches. Another feature that stands out in this system is the Dedo-Duro software, which comes pre-installed in the equipment and allows for maps and work reports on your personal computer, tablet or smartphone!
Spraying boom and frame
The Mechanical Boxer 4 x 2 features 25 or 27 meter booms that ensure great operational capacity. In addition, its central frame has a spring-damping system which, by means of adjustment, ensures minimal oscillation. The preload on the springs must be adjusted: the higher the preload, the more rigid the mechanism will be. The Boxer also has several hydraulic accumulators to cushion the dynamic movements that the spraying booms and frame components undergo. These accumulators are used in the extending and retracting cylinders, in the frame height and geometry cylinders.
Spraying control and pump
The Mechanical Boxer 4 x 2 uses a centrifugal pump with electronic flow control to ensure uniform pressure in the system. In order to optimize its service life, it can be made from cast iron or stainless steel and is driven by a hydraulic motor with 170 L/min at 2 bar capacity at the tip of the nozzle. Also, the mechanical seal on the pump is standard silicon carbide. Spraying in the Boxer M 4 x 2 self-propelled sprayer is controlled by an electronic controller that offers the best performance, maintaining pressure in the nozzles even with speed variations. Electric valves are responsible for actuating spraying in the 7 sections.
Duo React System
Optional on the Mechanical Boxer 4 x 2 self-propelled sprayer, Duo React consists of a double-nozzle pneumatic valve body and a compact control system. This system allows for increasing yield, because the operator can vary the speed range, maintaining the same droplet aspect, automatically alternating nozzles based on pressure and droplet size. It also optimizes operating performance, as the operator doesn’t need to leave the cab to change nozzles when switching the application rate: a simple console performs automatic or manual switching between nozzle A, nozzle B or nozzles A+B.
Premium features built into all machines
Access ladder and chemical inductor
The hydraulically actuated front ladder provides comfort and convenience to the operator: with a simple touch of the pedal, it raises or lowers. The chemical inductor in turn has 34 liter capacity: just place the container inside the mixer, press it against the rotating washer nozzle and operate the side lever to clean the container. Moreover, the tank of the Mechanical Boxer 4 x 2 self-propelled sprayer has an internal cleaning system to remove chemical residues that only works with the sprayer pump activated. Thus, only travel with the mixer locked into its rest position, otherwise it may damage the component and cause damage to the machine.
Pneumatic suspension of the Boxer M self-propelled sprayer
The Mechanical Boxer 4 x 2 self-propelled sprayer is equipped with an active pneumatic suspension system and leveling valves that identify soil unevenness and act to fill or empty the air in the pneumatic cushions. This circuit provides optimal operator comfort and minimal oscillation transfer to the booms. In addition, pneumatic suspension increases tire life, reduces fuel consumption and entails a lower maintenance cost, as there are no spring breaks or lubrication points. Furthermore, replacements are easier, load distribution between axle units is balanced and total dead weight is reduced.
Cab and wheel set
Designed to provide ergonomics and operator safety, the Mechanical Boxer 4 x 2 self-propelled sprayer’s cab has a large window area, offering a privileged view of the work space, including the main tank and spraying booms. It also has cooling and ventilation systems that ensure greater comfort. As for the wheel set, the Boxer comes equipped with 12.4 x 36 diagonal tires, with 12 plies (standard), or IF 320/85 R36 radial tires (optional), ensuring longer service life and flotation, as well as less soil compaction. Furthermore, the farmer has the possibility of purchasing the Boxer with a tubular or rounded row opener to reduce crop crushing during operation.
