The invention provides a mini-tiller with differential and power switching functions. The mini-tiller comprises a gearbox and a transmission shaft, wherein a gear shifting gear is arranged on the transmission shaft, a gear shifting pulling mechanism is arranged on the gearbox, a power switching mechanism is also arranged on the gearbox, and comprises a second spline sleeve and a power switching pulling mechanism, the second spline sleeve is arranged on the front end of the transmission shaft in a sleeving manner, the power switching pulling mechanism is arranged on the gearbox, a position limiting element is arranged on the power switching pulling mechanism, and a stop element is arranged on the gear shifting pulling mechanism. The mini-tiller has the advantages that the switching-in and switching-off operations of the power of the work mechanism can be realized through pulling the second spline sleeve to realize the combination and the separation with a power input shaft of a work mechanism, through the matching of the position limiting element and the stop element, the pulling to a retreating gear in the work process is avoided, people injury due to backwards retreating mini-tiller in the work process is prevented, the differential effect can be realized, further, the steering in the walking process is convenient to realize, the operation is convenient, and meanwhile, the differential lock function is realized.
