The above-mentioned agricultural tractor has a cooling fan that supplies air to the engine radiator in such a way that the cooling exhaust air after passing through the radiator is discharged to the front and outside of the engine bonnet. This is designed to prevent the air inside the engine bonnet, which has been heated by heat radiation from the engine, from flowing into the control section behind the driving section.

In general, the front lighting should be good from a high position, the steering direction display should be placed high to make it easier for others to see, and most of the part should be located under the hood to make it less likely to be damaged.
Electrical equipment such as headlights and direction indicators are mounted at a high level at the front end of the engine bonnet, with some of the parts extending into the bonnet.

損する虞れが大であつた。 Therefore, there is a large risk that the hot cooling exhaust air hits these electrical devices, deforming the resin covers of the electrical devices, or heating the sealing material and the wire sheathing material, thereby deforming or damaging them.
本考案の目的は、熱い冷却排風による上記トラ
ブルを回避できるようにすることにある。 The purpose of the present invention is to avoid the above-mentioned troubles caused by hot cooling exhaust air.

り、その作用・効果は次の通りである。
The feature of the present invention is that, in the drive unit structure of the agricultural tractor described at the beginning, electrical equipment is attached to the front end of the upper bonnet part, and cooling exhaust air flows into the internal front end of the upper bonnet part. The reason is that a wind shielding member is attached to the upper bonnet portion to prevent this from occurring, and its functions and effects are as follows.
ラジエータからの熱い冷却排風が上記ボンネツ
ト部分内の前端部に流入して電気機器に触れない
ように、排風のボンネツト内部分への流入を遮風
部材が防止する。
A wind shield member prevents the hot cooling exhaust air from the radiator from flowing into the hood portion so that the hot cooling exhaust air does not flow into the front end of the bonnet portion and touch the electrical equipment.
また、遮風部材は上部ボンネツト部分に付設さ

ことができる。 In addition, since the wind shield member is attached to the upper bonnet part, when the upper bonnet part is opened and closed, the wind shield member is also opened and closed at the same time with respect to the lower bonnet part, and the lower part of the wind shield member in the lower bonnet part is opened and closed. can be opened from above.

できた。
As a result, while maintaining a good control environment, work such as inspection and repair of the lower part of the wind shield inside the bonnet can be performed in a highly efficient manner without the need for the associated effort of attaching and removing the wind shield. It is possible to prevent electrical equipment and associated sealing materials from being heated by the engine cooling exhaust air, creating a state in which electrical system troubles are less likely to occur, and thereby rationally avoiding conventional troubles. I was able to provide a partial structure.
