。Examples of agricultural tractors that can be used for this purpose include the Jikatill (
As shown in Japanese Patent No. 56-155933, the front wheel transmission shaft is generally located below the engine.

の分、機体の本体全体を高く設置する必要が生じ、機体
重心が高くなって安定性を低下させていた。However, arranging the front wheel transmission shaft in the above-mentioned position has the following disadvantages. In other words, due to the nature of agricultural tractors, there are many opportunities to drive with working devices such as mowers attached to the lower abdomen of the aircraft, and to drive on rough roads with many uneven surfaces. It was necessary to ensure sufficient ground clearance for the front wheel transmission shaft located at the bottom of the aircraft, which required the entire main body of the aircraft to be installed higher, raising the aircraft's center of gravity and reducing stability.
本発明は、このような実情に着目し、機体下腹部の地上
高を確保し乍らも機体重心を低くして、安定性を高める
ことのできる農用トフクタを提供することを目的として
いる。The present invention has focused on the above-mentioned circumstances and aims to provide an agricultural tofuctor that can secure the ground clearance of the lower abdomen of the machine, lower the center of gravity of the machine, and improve stability.
上記目的達成のためになされた本発明の特徴構成は、前
輪伝動軸をエンジンの横側方に位置させてある点にあり
、その作用・効果は次の通りである。The characteristic configuration of the present invention, which has been made to achieve the above object, is that the front wheel transmission shaft is located on the lateral side of the engine, and its functions and effects are as follows.
つまり、従来まで機体本体中腹の最下部に位置していた
前輪伝動軸をエンジンの下方から横側方へ移行したこと
で機体中腹の最下部を示す対象が他の箇所に変更されて
最低地上高が高くなり、そしてその差の分だけ機体本体
を下げても、前輪伝動軸をエンジンの下方に配置した場
合とほぼ同じ高さの地上高を確保できるようになった。In other words, the front wheel transmission shaft, which had previously been located at the bottom of the fuselage, has been moved from below the engine to the side, and the target indicating the lowest part of the fuselage has been changed to another location, resulting in a minimum ground clearance. became higher, and even if the main body of the aircraft was lowered by that difference, it became possible to secure almost the same ground clearance as if the front wheel transmission shaft were placed below the engine.
その結果、従来と同じだけの地上高を確保し乍らも、
機体本体を下げて重心を下に移動させることで機体バラ
ンスの回復と安定性の向上が望めるようになった。As a result, while maintaining the same ground clearance as before,
By lowering the main body of the aircraft and moving the center of gravity downward, it is hoped that the balance of the aircraft will be restored and stability will be improved.
以下、本発明の実施例を図面に基づいて説明する。 Embodiments of the present invention will be described below based on the drawings.
