A pull-type mower conditioner includes a crop cutting assembly that severs crop material from the ground and a lift mechanism configured to raise and lower the crop cutting assembly to a desired height having at least one lift cylinder and a hydraulic lift circuit supplying hydraulic fluid to the at least one lift cylinder. The mower conditioner also includes a conditioning mechanism receiving the severed crop material from the crop cutting assembly. The conditioning mechanism includes a pair of counter-rotating conditioning rolls to condition the crop material and a tensioning assembly that urges the conditioning rolls relatively toward one another and resists their separation. The tensioning assembly includes a pair of hydraulic tension cylinders and a hydraulic conditioner circuit configured to supply hydraulic fluid to the tension cylinders. The hydraulic tension circuit has a supply line leading to a supply valve, wherein the supply line connects to the lift circuit.

[ABSTRACT] To provide a mower with which a mowing cord can be kept in an appropriate protruding state, in a mower in which a mowing cord 11 of resin is wound on a rotating body 1, the rotating body 1 is provided with a winding member 3 on which the mowing cord 11 is wound, the winding member 3 has a first peripheral concave groove 38 and a second peripheral concave groove 39 on which the mowing cord 11 is wound, and a winding portion 11d of the mowing cord 11 is wound as to be aligned from an inner side in a diameter direction to an outer side within each of the first peripheral concave groove 38 and the second peripheral concave groove 39.
摘要:
A motion driven cooling system configured to operate with one or more transportation devices. The motion driven cooling system includes a moving object in communication with a transportation device. The moving object transfers power from the movement of the transportation device and operates a water pump system and a fan system. The cooling system includes a water housing configured to retain water. The water pump communicates with the moving object and is configured to move water from the water housing to a second location where the water passes through one or more elements and returns to the water housing. The fan communicates with the moving object and is configured to move air across the water at the second location so as to lower the temperature of the air. An outlet port directs the flow of air as desired.

The present invention relates to an agricultural machine comprising an improved device for controlling a shield. Said agricultural machine has at least one working tool (2) which can be driven by a drive means (3) which can have a variable drive speed, at least one movable shield means (4) which can be moved at least between operational and non-operational positions, and a device for moving said at least one shield means (4), comprising at least one adjusting actuator (7) and a device for locking the shield means. The machine (1) is characterised in that the movement device has a circuit for controlling the actuator which includes the locking device, which circuit automatically converts a variable input quantity into a control quantity which can adopt a first control value used for preventing said adjusting actuator from being moved out of a first configuration, the input quantity being a value which is a function of or dependent on the drive speed of the drive means (3) or on the working speed of the at least one tool (2) in question.
摘要:
A corn header (10) for a combine harvester (12) capable of lifting stalks that have fallen sideways in a row is provided. The corn header (10) includes a frame (16), a plurality of row units (18) and a plurality of row dividers (20) for guiding crop plants toward the row units (18). The frame (16) is mounted to a forward end of the combine harvester (12). The plurality of row units (18) extends forward from the frame (16). Each row divider (20) is connected to and extends forward of at least one row unit (18), and includes a conveyor (30) connected to a lateral side (32) of the row divider (20) for the purpose of lifting and propelling crop plants into the corn header (10). In a preferred embodiment, the conveyor (30) is an auger including a helical flight having a non-circular profile or a plurality of notches to increase its ability to lift and propel crop plants into the corn header (10).
