Recently, it has become relatively common to carry out simple civil engineering work by attaching a dozer blade or other front-loading device to the front of a walk-behind tiller, but in this case, it is necessary to protect the engine located at the front of the machine. As for the structure, there is one in which the frame supporting the engine protrudes ahead of the engine, giving it a function similar to the bumper of a passenger vehicle.
機体前部にドーザブレード等を取付けて簡単な
土木作業を行う場合、前述のようにフレームを前

As described above, by using the U-shaped protector in plan view, a structure was obtained that protects the front part of the machine body where the engine, which is one of the important structures of a walk-behind cultivator, is located. This makes it possible to prevent damage to the aircraft body due to collision contact with other obstacles during work with a front-mounted work device such as a dozer blade attached.
そして、プロテクタの前部に前装作業装置連結
支持用の支持ブラケツトを取付けることにより、
前装作業装置専用の支持フレームが不要になつて
構造の簡素化も図ることができた。 Then, by attaching a support bracket for connecting and supporting the muzzle-loading work equipment to the front part of the protector,
A support frame dedicated to the front loading work device is no longer required, and the structure can be simplified.
