The plugs for the plug-in couplings can be found on the right-side mounting part for the tractor. They are connected to the hydraulic valve either directly or with hose lines.
FUNCTIONS Functions Implement locking mechanism 4.1.1 Mechanical implement locking mechanism Skid-steer and Euro change frames ⚠ WARNING Risk of injury due to implements falling down! The implement may fall down if the implement locking mechanism is open or not locked correctly. This can cause serious injury to persons standing in the surrounding area.
Page 34
FUNCTIONS Skid-steer change frame The mechanical implement locking mechanism on skid-steer change frames is actuated manually. To attach implements, the edge of the mounting surfaces is pushed into the mounting on the implement. As soon as the implement is resting on the change frame, the locking mechanism is closed with the lever.
FUNCTIONS Euro change frame The mechanical implement locking mechanism on Euro change frames is actuated manually. The implement is hinged with its hooks on the hook catch on the change frame. At the bottom, the implement is resting on the stop of the change frame.
Page 36
FUNCTIONS Lifting The 2 lifting cylinders are extended and thus raise the lifting arm and the implement. Without parallel motion, the angle between the lifting arm and the implement remains constant so that the implement changes its orientation. With parallel motion, the angle between the lifting arm and the implement changes so that the implement maintains its original orientation.
Page 37
FUNCTIONS Scooping The 2 implement cylinders are retracted and thus swivel the implement upwards. The implement scoops. B0AE Fig. 21 Scooping function Legend Implement cylinders on the left and right Implement Dumping The 2 implement cylinders are extended and thus swivel the implement downwards.
FUNCTIONS Float position ⚠ WARNING Possible risk of injury due to unexpected movement! If the front loader is not completely lowered, a vacuum may form in the hydraulic cylinders during the float position. This causes uncontrolled lowering of the front loader at a later time. This can cause persons to be injured or crushed.
FUNCTIONS Indicator for implement position (only H and P) The indicator for the implement position is located on the right implement cylinder. It allows the horizontal position of the implement to be read from the driver's seat. The rod is attached on the lower bearing pin and runs through the lug that is attached to the deflection triangle or the lifting arm.
FUNCTIONS Anti-lowering guard ⚠ WARNING Risk of injury and accident due to implement tipping off! The anti-lowering guard only prevents the front loader from lowering, however, it does not prevent accidental dumping of the implement. Persons whose presence is required near the load can be injured by the load falling down.
