摘要： An air cooling system for a vertical engine having a cylinder head projecting forwardly of a vehicle. The vehicle also includes a steering box disposed rearwardly of the engine, and a hood extending from the steering box and over the engine. This cooling system includes a cooling fan disposed above the engine; and engine cover enclosing the engine and opening downwardly, the engine cover defining an air suction opening in a region opposed to the cooling fan; an air intake opening defined in the steering box; and a shield for dividing an engine room formed forwardly of the steering box and under the hood into a front chamber for accommodating the cylinder head, and a rear chamber for accommodating the cooling fan. The shield includes a first shield member and second shield members.

摘要： A tractor for agriculture comprising an engine, a hydraulic stepless speed change mechanism having an output shaft, an input shaft connecting the engine with the hydraulic stepless speed change mechanism and having an extended portion, a PTO shaft connected in association with the extended portion, a running device, a transmission shaft connected in association with the output shaft, and a transmission change mechanism disposed at an intermediate portion of the transmission shaft, said transmission change mechanism being connectable and disconnectable of power transmission from the output shaft to the running device and capable of power transmission from the extended portion to the running device when said power transmission from the output shaft to the running device is cut. The tractor may be running even if the hydraulic stepless speed change mechanism is in trouble.
摘要翻译：一种用于农业的拖拉机，包括发动机，具有输出轴的液压无级变速机构，将发动机与液压无级变速机构连接并具有延伸部分的输入轴，与延伸部分相关连的PTO轴，运转装置，与输出轴相关联的传动轴，以及设置在传动轴的中间部分的变速机构，所述变速机构能够从输出轴向行驶装置输送动力，并且能够当从输出轴到运行装置的动力传递被切断时，从延伸部到运行装置的动力传递。即使液压无级变速机构出现问题，拖拉机也可能运行。
