User and maintenance manual Drago Gold 9. OPERATION OF THE MACHINE In the field the sunflower head is positioned with the points between the rows of sunflower plants; the points open and line up the row with the gathering system. The harvesting chains firmly capture the plants in the compartments between the rubber pads and carry them towards the cutting disks present under the groups. Once the position of the cutting disks has been surpassed, the plant is separated from the root, but the grip of the pads ensures that it is transported to the auger which conveys the product flows of the various rows towards the conveyor duct of the combine harvester. 9.1 GENERAL INFORMATION The gathering section of the Gold Dragon consists of 3 mechanisms that work together to lead, collect, regroup and process the sunflower plant and flowers. This section of the manual gives an overall description ...
Page 42
User and maintenance manual Drago Gold Take care to limit the extension of the cutter lifting cylinders when working with the head on the ground (H) to prevent the lever (E) from coming into contact with the ground or the blades (F). The stalk chopper can work by following the contour of the ground (minimum cutting height) from a minimum height “H” of 0.15 m to a maximum “I” of 1.5 m. Rev. 00 Original instructions ...
User and maintenance manual Drago Gold INDIVIDUAL COMPONENT PROTECTIONS The Drago Gold heads are equipped with individual protections on the main components to prevent damage caused by possible foreign objects. The protection consists of a radial pin clutch installed inside the rotating gears in sealed housings. These clutches do not require maintenance as long as they operate in an oil bath environment. Furthermore, the frictions are already properly set by the parent company and cannot be adjusted. Gathering chains and cutting disks Both the gathering chains on each row of the Gold Dragon have their own radial pin clutch (B) inside the gears (A), which protects both the chain and the disk connected to it. This allows each chain to work independently of the other in case a foreign object is encountered. If one of the two chains snaps, this brings the pads of the first one into contact with the pads of the second one, thus also causing the latter to snap and restoring the phase between the pads. ...

BEFORE ENTERING THE FIELD Always switch off the engine, adjust the parking brake, remove the key and attach the power supply safety lock on the lift cylinder before working under the machine or under the duct. Failure to attach the safety lock of the power supply can cause injury or death. Checks to be performed before entering the field: 1) Check that all attachment parts between the combine harvester and the sunflower head and its supports are NOT worn, damaged or corroded; 2) Verify that all safety guards are in place and that they are properly secured. 3) Clean the coupling parts; 4) Perform lubrication operations (see lubricants table); 5) Carry out the checks on the main machine (combine harvester‐forage harvester) required by the manufacturer; ...
User and maintenance manual Drago Gold 10.1 STARTING WORK IN THE FIELDS Start the duct at a low speed to verify that the sunflower head functions as required. Operate the combine harvester and proceed at low speed until you are familiar with the head. After making several sweeps, stop the head and switch off the combine harvester. After securing it, examine all the bearings to check for excessive heating. All bolts must be tightened and the gathering chains must be tensioned. Make all necessary adjustments. See Section 11. Danger: switch off the combine harvester, activate the brake, remove the key and lower the duct safety stop supports before approaching the head. Failure to do so could result in serious injury or death. Drive and operate carefully Drive carefully to keep the sunflower head in rows. Never exceed the flow capacity of the sunflower head or combine harvester. Excessive loading can cause breakage. Start at a low speed and gradually increase until locating the correct working speed. Listen in order to identify the presence of jerky movements, friction or unusual noises. The correct working speed depends on the conditions of the crop and the knowledge and experience of the operator. Important: combining the speed of the sunflower head with ground speed is very important for a good harvest and to minimise losses. Ideally, in sunflower standing conditions, the chains should slide slightly faster than the stalks that enter the row. For best results, the drive shaft of the sunflower head should operate between 630 and 700 RPM. Note that this RPM range is not the duct speed. ...

User and maintenance manual Drago Gold 11.2 ADJUSTMENT OF GATHERING POINTS Danger: before repairing or adjusting any part of the sunflower head, activate the duct safety stop supports, the parking brake, turn off the combine harvester, remove the key and hang a warning sign on the operator's platform. Failure to do so could result in serious injury or death. Important: the working angle of the sunflower head must be set correctly before adjusting the points. See Section 11. 11.2.1 POINT ADJUSTMENT The head (A) must be adjusted with the points (B) that touch the ground (C) when the slides (E) are 4‐5 cm (D) away from it. In this way, it is ensured that, under finned product conditions, travelling with the slides (E) that touch the ground, the points (B) can still drop by the amount needed to compensate for head lifting due to the movement of the slides over ground elevations or obstacles. At the same time, the points can rise in front of obstacles due to the front end of the point that guarantees sliding of the point over the obstacle. An excessively low setting of the point can result in the front end becoming stuck in the ground with damage to the casing, while conversely too high an adjustment can be harmful in case of finned product as it does not allow the point to fit under the product and to lift it to carry it to the gathering chains.
