摘要： A lifting device comprising: a backframe (1) equipped at its bottom with a pair of arms (4); lifting element (R) between the pair of arms (4) and the backframe (1), and two forearms (10a) mounted on each side of the pair of arms (4) on an articulation spindle (11), each forearm comprising an attachment bracket (13) and, at the opposite end, an extension (15) beyond the articulation spindle (11). The end of the extension (15) has a recess (16) which is open in the direction away from the attachment bracket. A stop connected to the pair of arms comprises a transverse spindle (20) equipped, over part of its length and of its periphery, with a radial bulge (E). When the bulge (E) is housed in the recess (16), the forearm (10a) is immobilized relative to the pair of arms (4), whereas when the bulge is out of the recess (16), a limited angular excursion of the forearm (10a) relative to the pair of arms (4) is possible.

摘要： The invention provides a locking pin (G) comprising a loop (B) and means (R) for pivoting the loop on the locking pin so that said loop (B) may be brought back to surround the spindle (A) in which the locking pin is engaged so as to oppose removal of said locking pin. The pivoting means (R) comprise a mobile bearing (6) supported by two substantially parallel arms (8, 9), the assembly being such that in a "high" position the arms extend on a side which moves the bearing (6) to a maximum away from the opposite end (e) of the locking pin, whereas in a "low" position, said arms (8, 9) have rotated with respect to the "high" position. The locking pin may pass through the loop when the arms are in the "low" position but cannot pass through the loop when the arms are in the "high" position.

摘要： A mowing arrangement includes a main, mobile frame to which a base or first carrier part or frame is mounted for being pivoted vertically by a remotely operable hydraulic motor. Mounted to the base carrier frame is a second carrier part to which arms supporting opposite side and front mowing units are attached. The front-mounted mowing unit is mounted to the second carrier part through the agency of a fourth carrier part, in the form of a parallelogram linkage that includes the support arm for the front-mounted mowing unit. The second carrier part is mounted for pivoting about a transverse, horizontal axis so that the cutting angles of each of the mowing heads can be remotely adjusted by pivoting the second carrier part. A third carrier part is fixed for movement with the second carrier part and supports a drive transmission having output shafts respectively coupled for supplying power to the three mowing heads.

摘要： A mowing arrangement includes three mowing units with which are associated a drive system including transmissions associated with each unit that are alike to the extent that the mowing units may be easily exchanged with one another. Specifically, one of the mowing units has an angle drive transmission while the transmissions on the other two mowing units are belt or chain drive transmissions. All transmissions are mounted for easy replacement whereby the angle drive transmission may be replaced by a belt or chain drive transmission like the other mowing units if it is desired to use the front mowing unit as a side mowing unit. A drive system variant includes two angle gear boxes used as a power-receiving transmission, with the result that all of the mowing units can be constructed exactly the same.

摘要： Lifting device (D) comprising a frame (4) for fixing to a tractor chassis, the frame being fitted, on its lower part, with lower securing member (A), articulated about a transverse axis and extending towards the front, with its ends capable of being coupled to the two lower fastening points of a tool, and on its higher part, with a median upper securing members (16); lifting members (14) are provided between the frame (4) and lower securing members. The lower securing members (A) comprise, firstly, a lower primary structure (19), articulated at its rear part on a transverse axis (18) carried by the frame (4), and provided on the front with two longitudinal lateral extensions (21) in which a transverse bearing (26) is provided, and secondly, a forearm (29) associated with each longitudinal extension 921) and articulated about an axis (34) carried by the bearing. The forearms are independent; each (29) when in a work position, comes to rest by means of its rear part, under a stop integral with the structure (19), so as to block itself on lifting of the structure or on load raising. When the forearm (29) is free of its load, it can be folded upwards in relation to the frame (4), for a storage position. The forearm is provided, in a high position of the frame (19), with a stationary locking device to prevent both the structure and forearms from dropping, and to prevent the latter from rotating in relation to said structure.
