    • An operator enclosure for an agricultural tractor has a rollover protective structure (ROPS) in which the front side of the ROPS (12) extends upward above the left, right and rear sides of the ROPS (12) and terminates at a front upper cross member (32) extending laterally between left and right front upright corner members (14, 16). A roof pan (48) is placed at the top of the ROPS (12) that has a generally horizontal top panel (50) at about the same height as the front upper cross member (32). The top panel (50) of the roof curves downward to form left, right and rear side panels (52, 54) extending downward from the top panel (50) to the height of the upper members (30) of the ROPS (12) along the left, right and rear sides. There is no front panel on the roof extending downward from the top panel (50). The windshield (40) is extended upward into what had previously been the front panel of the roof. This improves the front upward visibility, an feature particularly useful in operating a front end loader on the tractor.
    • 用于农用拖拉机的操作器外壳具有翻转保护结构(ROPS),其中ROPS(12)的前侧在ROPS(12)的左侧,右侧和后侧向上延伸,并且终止于前上横向构件 (32)在左右前直立角部件(14,16)之间横向延伸。 顶盖(48)放置在ROPS(12)的顶部,ROPS(12)的顶部具有大致水平的顶板(50),其高度与前上横梁(32)大约相同。 屋顶的顶板(50)向下弯曲以形成从顶板(50)向下延伸到ROPS(12)的上部构件(30)的高度的左,右和后侧板(52,54) 沿左,右,右两侧。 屋顶上没有从顶板(50)向下延伸的前面板。 挡风玻璃(40)向上延伸到以前是屋顶前面板的位置。 这提高了前向上的可视性,这特别适用于在拖拉机上操作前端装载机。

    • A front end loader (30) is detachably mounted on a tractor (10), and has a boom (60) which is swingable by a pair of cylinders (78) and which carries a loading bucket (74). The cylinders (78) need to be operated during mounting and dismounting and therefore have to be connected to the trac­tor hydraulic output in this period as well as during work­ing of the loader (30).
      In order to facilitate mounting and dismounting without stress to hydraulic hoses (86) running between the tractor (10) and loader (30), the hydraulic output from the tractor is located near the front thereof and the hoses (86) are routed alongside loader mast beams (44) and the boom (60) to the cylinders (78). The hoses (86) have a curved portion (216) adjacent the pivotal connection of the boom (60) and are supported by a swingable bracket (234) on the mast beams (44).
    • 前端装载机(30)可拆卸地安装在拖拉机(10)上,并且具有可由一对气缸(78)摆动并具有装载斗(74)的悬臂(60)。 气缸(78)需要在安装和拆卸过程中进行操作,因此在此期间以及在装载机(30)的工作期间必须连接到拖拉机液压输出。 为了便于安装和拆卸而不会对在拖拉机(10)和装载机(30)之间运行的液压软管(86)施加压力,来自拖拉机的液压输出位于其前部附近,并且软管(86)沿着装载机 柱塞梁(44)和悬臂(60)连接到气缸(78)。 软管(86)具有与悬臂(60)的枢转连接相邻的弯曲部分(216),并且由桅杆梁(44)上的可摆动支架(234)支撑。
