Abstract: A cooling system for an engine of a lawnmower. The engine has a muffler through which exhaust gases exit the engine and is cooled by a liquid coolant. The cooling system includes a heat exchanger operatively connected to the engine to receive the liquid coolant from the engine at a first temperature and return the liquid coolant to the engine at a lower temperature. A fan mounted above the heat exchanger is operable to draw or pull an air flow in a standard direction upward through the heat exchanger. The heat exchanger and fan are oriented in an inclined orientation such that the air flow is directed upward and away from the operator station of the lawnmower. The cooling system also has a generally tubular baffle surrounding the muffler at least partially isolating the engine from heat radiating from the muffler. The baffle is configured such that exhaust leaving the muffler causes air to be inducted into the areas between the muffler and the baffle by an aspiration effect created by the exiting exhaust gases.
Abstract translation: 割草机发动机的冷却系统。 发动机具有消声器，废气通过该消声器离开发动机并被液体冷却剂冷却。 冷却系统包括可操作地连接到发动机的热交换器，以在第一温度下从发动机接收液体冷却剂，并在较低温度下将液体冷却剂返回到发动机。 安装在热交换器上方的风扇可操作以沿着标准方向将空气流向上拉动或拉动通过热交换器。 热交换器和风扇以倾斜的方向定向，使得空气流向上并远离割草机的操作台。 冷却系统还具有围绕消音器的大致管状挡板，至少部分地将发动机与消声器辐射的热量隔离。 挡板被构造成使得离开消声器的排气通过由排出的废气产生的抽吸效应引起空气被引入到消音器和挡板之间的区域中。

Abstract: A ZTR lawnmower having and first and second drive wheels and first and second control levers to control the direction and speed of rotation of the first and second drive wheels. The lawnmower further includes a park brake system operatively interconnected with at least one of the drive wheels, and an interlock mechanism interfacing with the parking system. The park brake interlock mechanism includes a parking brake handle movable between an engaged position and a disengaged position to cause the park brake system to respectively resist and not resist rotation of the at least one drive wheel. The interlock mechanism interfaces with the park brake handle and the control levers such that when the first and second control levers are in the neutral position, the interlock mechanism permits the parking brake handle to be placed in the engaged position, and when the first and/or second control levers are not in the neutral position, the interlock mechanism prevents the parking brake handle from being placed in the engaged position.
Abstract translation: ZTR割草机具有第一和第二驱动轮以及控制第一和第二驱动轮的旋转方向和速度的第一和第二控制杆。 割草机还包括与至少一个驱动轮可操作地连接的驻车制动系统，以及与停车系统相连接的互锁机构。 驻车制动互锁机构包括可在接合位置和分离位置之间移动的停车制动手柄，以使驻车制动系统分别抵抗并且不阻止至少一个驱动轮的旋转。 联锁机构与驻车制动器手柄和控制杆接合，使得当第一和第二控制杆处于中立位置时，联锁机构允许驻车制动器把手放置在接合位置，并且当第一和/ 或第二控制杆不处于中立位置时，联动机构防止驻车制动器把手处于接合位置。
