However, in the above-mentioned conventional backhoe, the balance weight is relatively large, and the balance weight is fastened to the swivel base by fastening with fasteners such as bolts. The balance weight is obstructed when performing maintenance on the engine, etc. in the engine room even when the hood is open. It is difficult to perform maintenance work on the lower part of the vehicle, for example, a work of discharging engine oil, a work of discharging cooling water of a radiator, and a work of replacing an oil filter. In particular, since the lower part of the engine is lower than the frame on the lateral outside or the rear outside of the turntable, the balance weight further hinders maintenance. Therefore, if the balance weight is removed, the open space to the engine room becomes larger and maintenance work becomes easier.However, since the balance weight is quite heavy, a crane or the like is required for attaching and detaching the balance weight. There are drawbacks, such as time and effort.
