    • A lawn mower having a driver's section and a grass cutting unit forwardly of a vehicle body; an engine mounted between front and rear wheels; and a pair of main frames extending longitudinally of the vehicle body, each of the main frames including a front frame member, and a rear frame member connected to the front frame member and disposed at a lower level than the front frame member. The engine is mounted below the main frames between the front and rear wheels, and has a radiator disposed rearwardly of the engine and having an upper portion projecting upwardly of the rear frame members. The engine is surrounded by a first cover assembly including side covers depending respectively from the main frames, lower covers connecting the respective side covers to lower positions of the engine, and a front cover for closing an area forwardly of the engine. The first cover assembly defines first ambient air intake openings. A second cover is disposed rearwardly of the driver's section for covering the upper portion of the radiator. The second cover defines a second ambient air intake opening in a forward portion thereof. Cooling air flows produced by a fan disposed adjacent the radiator are drawn through the first and second ambient air intake openings, at least a large part of the cooling air flows being exhausted rearwardly through the radiator.

    • A front mower having a grass cutting unit connectable to a front portion and a grass catcher connectable to a rear portion thereof, comprises a main frame structure extending longitudinally of a mower body. The main frame structure includes a pair of right and left front frames and a pair of right and left rear frames. The rear frames have front ends thereof connected to rear ends of the front frames, respectively, such that the rear frames are lower in level than the front frames. A lower auxiliary frame structure is suspended from the main frame structure. Front wheels and rear wheels are supported by the main frame structure. Axles of the rear wheels are swivelable about a vertical axis in a caster-like way to steer the mower. An engine is disposed in a region of the front frames between the front wheels and rear wheels and supported by the lower auxiliary frame structure. The engine and oil pan are disposed above the lower auxiliary frame structure. A driver's seat is disposed above the front frames. A fuel tank is disposed in a region of the rear frames.
    • 具有可连接到前部的草切割单元和可连接到其后部的草地捕获器的前割草机包括沿割草机主体纵向延伸的主框架结构。 主框架结构包括一对左右前框架和一对左右后框架。 后框架的前端分别连接到前框架的后端,使得后框架的水平比前框架低。 下部辅助框架结构从主框架结构悬挂下来。 前轮和后轮由主框架结构支撑。 后轮的车轮可以以类似脚轮的方式围绕垂直轴线旋转以引导割草机。 发动机设置在前轮和后轮之间的前框架的区域中,并由下辅助框架结构支撑。 发动机和油底壳设置在下辅助框架结构的上方。 驾驶座位于前框架上方。 燃料箱设置在后框架的区域中。
