    • There is disclosed a semi-mountable plough comprising an elongate plough frame having a long forward frame section (1) carrying a plurality of plough bodies (2), a short intermediate section (3) pivotally connected to the rear end of the forward section (1), and a rear frame section (5) pivotally connected at its forward end to the rear of the intermediate section (3), with the plough being of a reversible type and the section (1, 3 and 5) being pivotable relative to each other in a generally horizontal plane to take-up new positions suitable for movement of the plough in a reverse direction. The rear frame section (5) is pivotable about a horizontal pivot (11) so as to follow any unevenness in the ground, and an actuator (12) is coupled with the rear frame section (5) and is operable in a first mode to allow limited pivotal movement of the rear frame section (5) about horizontal pivot (11), and in a second mode to prevent such pivotal movement.
    • 公开了一种半安装式犁,其包括具有长的前部框架部分(1)的细长犁架,所述长的前部框架部分(1)承载着多个犁体(2),短的中间部分(3),其枢转地连接到所述前部的后端 1)和后框架部分(5)在其前端枢转地连接到中间部分(3)的后部,犁具有可逆类型,并且部分(1,3和5)可相对于 彼此在大致水平的平面上,以相对于犁的移动适应新的位置。 后框架部分(5)围绕水平枢轴(11)可枢转,以便跟随地面中的任何不均匀,并且致动器(12)与后框架部分(5)联接,并且可以以第一模式操作 允许后框架部分(5)围绕水平枢轴(11)的有限枢转运动,并且以第二模式来防止这种枢转运动。
