    REMOTE CONTROL AND JOYSTICKS

    
    TC BASIC

    Sigma 4 supplies as standard a supplementary dedicated valve chest which is operated by means of a very handy cable joystick. The hydraulic system is customized for each tractor model and so is the joystick positioning in the cabin to guarantee the best comfort and adaptability. The above equipment keeps free the original tractor valve chests and to control, in an easy and precise way, all functions of the front loader. The lever is also provided with a safety locking system meant to prevent accidental movements.
    
     

    
    TC PROFI

    Optional electric push-buttons allow the operator to control electro-hydraulic selectors for the operation of implements with additional hydraulic services. If compatible with the tractor fitted, 2 supplementary buttons enable the high-low transmission functions to be operated via the joystick.
    
     

    
    TC SPEED

    This is a proportional electronic control conforming to CAN BUS technology. The joystick is fully ergonomic and, thanks to the tiny dimensions, it can dramatically reduce the operator's strain while working, as well as being easily positioned on the armrest of the tractor seat for full accessibility and ease of operation.
    Besides standard loader functions such as lift/lower and tip/crowd, it is possible to select the boom float function (a standard feature with this type of joystick control), to adjust the speed of each single operation and sensitivity, to pilot electro-hydraulic selectors for additional hydraulic services. On top of this, there are push buttons for the Fast/Slow operation and emergency control.

    EURO IMPLEMENT FACEPLATE

    
    EURO SYSTEM

    Designed to allow the easy and quick change of implements. The loader is supplied, on a standard basis, with the EURO system conforming to ISO 23206 standards. This allows the fitting of all implements manufactured by third parties and conforming to these standards.
    Alternatively, a heavy-duty SIGMA 4 implement fitting system can be supplied. The latter can receive only attachments manufactured by ourselves.
    
     

    
    HYDRO SYSTEM

    Designed for extra comfort, the change of implements can be operated from the tractor seat.
    The hitching and un-hitching is performed by simultaneously pressing 2 buttons on the joystick, thus avoiding unintentional operation and granting the highest possible level of safety.
    The HYDRO SYSTEM requires a dedicated supplementary hydraulic line for its functioning.
    
     

    
    DUAL SYSTEM

    Designed to allow the simultaneous use of implements either conforming to the EURO standards or having the MX hitching type. For the latter it is necessary to fit relevant so-called “MX adaptors”.
    
     

    
    COMBI SYSTEM

    Designed to allow the simultaneous use of implements either conforming to the EURO standards or having the ALO/Q3 hitching type. Moreover, by fitting dedicated “MX adaptors”, the same faceplate can also receive implements having the MX hitching type.

    SUBFRAMES

    
    
    

    Subframes are a significant achievement for SIGMA 4 and a reference for everybody in the industry. They are connected to the tractor main frame in 3 points (front axle, bell-housing/gearbox area, rear axle) for an ideal distribution of loads, a solution that offers the best in terms of rigidity and ruggedness of the unit, for unsurpassed performance. Every tractor has a proper mounting subframe. Particular care is also put in the design of mounting solutions for full accessibility to tractor for standard service operations, without having to remove any parts.
    Steering angles are not impaired and full compatibility is assured with mudguards, front linkages, different types of pick-up hitches and cabs.

    HYDRAULIC SYSTEM

    
    FLASH SYSTEM

    The “FLASH” multi-connector device allows the operator to easily and quickly connect/disconnect, with a single operation, all hydraulic lines, thus avoiding possible connection errors.
    The device is fitted as a standard on TITANIUM and PLATINUM models, while it is an option on the GOLD and on the IRON ranges.
    
     

    
    GENIUS SYSTEM

    ANTI-BOUNCE SAFETY SYSTEM
    Two anti-shock accumulators provide enhanced comfort and safety during loading and transport phases. Shocks and stress on all components are significantly reduced when using the GENIUS system and the benefits are more evident as the speed and load increase. The device is a great achievement in terms of safety, operator's comfort and reduced stress for tractor tires and front drive components. It is fitted as standard with a cross cover which protects it from impacts and wearing agents. Standard feature of the GENIUS system is also an exclusion tap which enables its switch-off whenever needed.
    The device is fitted as a standard on GOLD, TITANIUM and PLATINUM models, while it is an option on the IRON range.
     

    
    QRC FLASH

    Convenient tool for connecting the hydraulic pipes of implements fitted with a 3rd hydraulic function. With a single operation, the implement's hydraulics are easily connected, even when pressurized.
    The QRC FLASH can be easily cleaned, thus avoiding any dirt in the loader hydraulic system, and by consequence into the tractor's hydraulic system.
    
     

    
    3SL - 4SL

    They allow the use of implements with additional hydraulic requirements, such as grabs, side-shifts, extra-lifts, etc.
    The electro-valves are supplied as standard with a plastic cover to protect them from impacts and wear.

    IMPLEMENT SELF-LEVELLING

    
    

    
    HYDRAULIC SELF-LEVELLING SYSTEM
    The implement's self-levelling system is performed by the proportionally-sized rams A connected by a closed circuit to the bucket's rams B. When lifting the boom, the compensator rams expel oil that goes into the bucket's rams and determines the automatic implement's self-levelling. The same happens when the boom is  lowered.
    
    The compensator cylinders determine also create an increase of the lifting power: the load Q on
    the implement generates a pressure first in the bucket's rams and then, consequently,  in the compensator rams. The power increase deriving from above is about 10-12% of the load Q.
    The hydraulic self-levelling system is supplied as standard in the front loaders series “H”.
     

    
    

    MANUAL IMPLEMENT LEVELLING
    It is a distinctive feature of our “F” series.
    The operator, by using the joystick, has full control of the angle of the attachment in relation to the boom angle while lifting and lowering the loader.
     

    
    

    MECHANICAL SELF-LEVELLING SYSTEM
    The mechanical self-levelling system is supplied as standard on the front loaders series “M”.
    By means of this system, the load is held in the same position throughout the full travel of the boom, resulting in an increased lift capacity.
    The variable geometry parallel linked system creates large working angles, thus enhancing performances and ease of operation.

    MAINTENANCE AND BENEFITS

    
    

    EASY MAINTENANCE
    We design our subframes as to allow access to tractor parts that need regular servicing.
    
     

    
    

    HYDRAULIC PIPE SUPPORT
    Our front loaders are fitted as standard with a flex pipe support plate that can be adjusted in 2 positions to serve the purpose either with quick couplers or with the FLASH SYSTEM.
    Pipes are securely and safely held when loader is disconnected from the tractor.
    
     

    
    

    BUCKET LEVEL GAUGE
    Standard feature to all of our models, the bucket level gauge allows the operator to easily check the angle of the implement to the ground from the tractor's seat and thus provide a very useful guidance for the operator.
    
     

    
    

    SUPPORT LEGS
    A distinctive feature of our supporting legs is their length, compared to our competitors, and with our fine-adjust-system allow safe loader removal on all ground conditions.
    During operation they are  locked on the inside of the loader boom without interfering in any way with the tractor's front wheels.
