WZ30-25 backhoe excavator loader is designed for agriculture,engineering or municipal projects.There are two types of WZ30-25 backhoe excavator loader.One is slide shift backhoe and the other is center mount backhoe or center pivot backhoe.The center mount backhoe has the backhoe mounted at the center of its rear frame.The advantage of this type is that it is more stable than the slide shift type because this design reportedly provides a wider stance and more ground clearance,making it ideal for sloped terrain and heavy loads but it needs more space.When the backhoe is close to building or some immovable objects,this type backhoe cannot play its part.However,when the backhoe is on a slope,the center mount type is much more stable and safe as it is not easy to tilt.
