Two optional working modes including Standard Power Mode and Fine Precision Control Mode to match garden shaping, farm land leveling, narrow municipal pipeline trenching and indoor small concrete light crushing construction tasks. All hydraulic cylinders adopt built-in micro anti-shock buffer valve design to eliminate tiny impact vibration during ultra-precision narrow yard and indoor light-load operation. Factory pre-installed full small-flow hydraulic breaker pipeline interface, compatible with 45-68mm mini hydraulic hammer without secondary refitting. Exclusive 3-pump load sensing hydraulic control dynamically distributes pump output flow according to real-time operation demand, reduces idle fuel consumption by 12% and improves overall operation smoothness by 18% compared to old generation mini machine models. Auto-shift travel system automatically switches high/low speed according to terrain traction resistance, making dozing and turning operation smoother. Auto idle function automatically reduces engine speed after joystick idle for 3 seconds to cut unnecessary fuel waste.
