The backhoe is a single device composed of three construction equipment. The operator only needs to turn the seat to change the working end during construction. The main job of the backhoe is to dig ditches to lay pipes and underground cables, lay the foundation of the building and establish a drainage system. When the backhoe driving on the uneven road, because often shake caused by suspension and tire deformation increased, leading to a large increase in rolling resistance, compared with driving on a good road, fuel consumption increased by 30%-50%, so it must be repaired, good maintenance of the construction road. Outside the initial construction should pay attention to the change of road conditions, choose the right tire pressure, to reduce fuel consumption.
