摘要： The invention relates to a plough having at least one plough body (13) whereby the plough body (13) includes a mouldboard (36) to which at least one mouldboard portion (37) is fastened with the aid of which the length of the mouldboard (36) is variable without the necessity of removing this mouldboard portion. The plough bodies (13) of the plough are capable of swivelling around an upward extending axis (47), which axis is disposed behind the mouldboard (36) of the plough bodies. The plough bodies (13) further include a supporting member (34A) which during operation is in contact with the furrow walls and comprises a plurality of strips. The plough bodies (13) are connected via coupling means (19) to a spring loaded mechanism (23 - 28) in such a way that on deflection of a plough body (13) one coupling means (19) is made inoperative whilst the other one is put into operation.

摘要： A plough has a frame beam (1) supporting plough bodies (5, 6). The front plough body (5) is pivotable about an upwardly extending axis (10), and part (26) of the mouldboard (23) of each other plough body (6) is pivotable about an upwardly extending axis (27). Adjustment is made through rod systems (12, 14; 34, 36) from a common rod (20). The rod (20) may be displaceable mechanically (by a screwthreaded spindle (37) or hydraulically (by a cylinder (43)). Adjustment may be effected automatically in response to the tractive force required to drive the plough through the soil.

摘要： A reversible plough has plough bodies (13) mounted in pairs on a frame beam (1). The plough bodies (13) are connected to the frame beam (1) by pivotable linkages (19) for upwards and downwards displacement. For some of the plough bodies, this displacement can be effected by hydraulic cylinders (36) controlled from the tractor to which the plough is hitched. Downwards movement of the plough bodies (13) is limited by stops (22) which are displaceable automatically into operative positions upon reversal of the plough.

摘要： reversible plough comprises a frame (1) on which plough bodies (11) are mounted. The plough bodies (11) can pivot about both vertical axes (6) and horizontal axes (10), the latter extending transversely of the travel direction (A). Supporting members (21) are provided for each plough body 111) for engagement with a side wall of a furrow cut by the respective plough body (11). A skim coulter (31) is provided for each plough body (11). The plough bodies (11) are arranged in pairs disposed one above the other, and behind each pair of plough bodies (11) there is a crumbling roller (32) for crumbling the soil of a furrow slice cut by the operative plough body of the respective pair. The positions of the plough bodies (11) about the axis (6) and the pressure applied by the crumbling rollers (32) is adjustable by hydraulic cylinders (24, 44).
