いようにした。(d) Means for solving the problem The present invention provides a mobile agricultural machine in which an engine base with an engine mounted thereon is mounted on a frame, and a bumper is attached to the front part of the frame. The front part is screwed so that it can move forward and backward through a vibration isolating material, and the material that is received from the frame is inserted between the front end of the engine base and the approximately vertical back surface of the bumper. is set upright, and an adjustment bolt, whose rearward protrusion length from the nut is larger than the distance between the support material and the bumper, is screwed from the front between the support material and the nut fixed to the front part of the engine base. Then, the hole for inserting the adjusting bolt drilled in the receiving member is made large enough to allow the vibration of the adjusting bolt, and the lower part of the receiving member is opened as a space for operating the adjusting bolt. This solves the above-mentioned problem by making it possible to easily move the engine according to the stretch of the belt, even if the belt that is constantly under tension is placed on the engine pulley. I tried not to fall out.

力調節を行なうことができる。 Also, even if the engine is tightened with a vibration isolator in place, the engine base and frame will vibrate, causing the adjustment bolt to loosen, but its head will come into contact with the rear surface of the bumper before falling off, causing it to fall off. The tension of the belt can be adjusted at any desired time.
更に、アジヤストボルトは受材の下方の開放部
から手を入れて調節する。 Furthermore, adjust the adjustment bolt by inserting your hand through the opening at the bottom of the receiving member.

な張力に設定することができる。(g) Effects of the invention The present invention provides a mobile agricultural machine in which the engine base 6 on which the engine 5 is mounted is mounted on the frame 1 as described above, and the bumper 3 is mounted on the front part of the frame 1. The rear part is screwed to the substantially horizontal rear part of the frame 1 so that it can be moved back and forth, the front part is screwed to the rear part of the frame 1 so that it can be moved back and forth, and the front end of the engine base 6 and the substantially vertical back surface of the bumper 3 A receiving material 11 is erected from the frame 1 between the receiving material 11 and a nut 26 fixed to the front part of the engine base 6. The adjusting bolt 30, which is larger than the distance l between the bumper 3 and the bumper 3, is screwed from the front, and the hole 27 for inserting the adjusting bolt 30, which is drilled in the receiving member 11, is inserted into the hole 27 to prevent the vibration of the adjusting bolt 30. The diameter of the receiving member is made as large as possible, and the lower part of the receiving member is opened as a space for operating the adjusting bolt. The engine 5 can be moved safely and easily together with the engine base 6 by inserting your hand through the opening below the member 11 and rotating the adjuster bolt 30. In this state, simply tighten the set bolt 10. The belt can be set to the appropriate tension.
しかも、前記アジヤストボルト３０はエンジン
５の振動により弛むが、その頭部がバンパー３に
受止められて抜け落ることがない。 Furthermore, although the adjuster bolt 30 loosens due to the vibrations of the engine 5, its head is received by the bumper 3 and does not fall off.
