The invention relates to a mini-sized multifunctional mini-
tiller which comprises a walking device, a depth limiting device, a rotary
tillage device, a gear shifting box, an engine and a control
handle. The walking device comprises two walking wheels which are arranged at the two sides of the gear shifting box in a
bilateral symmetry mode. The engine is arranged on the gear shifting box. The rotary
tillage device is arranged in front of the gear shifting box. The control
handle is arranged at the rear of the gear shifting box. The depth limiting device is arranged ahead of the rotary
tillage device. A speed change mechanism, a gear shift mechanism and a planetary differential mechanism are arranged in the gear shifting box. The engine transmits power to the gear shifting box through a
clutch wheel and a belt. A gear changing
handle and a
clutch handle are connected to the gear shifting box. A
throttle control key and a switch button control key are arranged on the control handle. By means of the gear shifting handle, the
clutch handle, the
throttle control key and the switch button control key, the mini-
tiller is controlled to carry out walking, depth limiting and rotary tillage operation. The mini-
tiller has the advantages of being simple in structure, convenient to operate, safe, efficient, capable of adapting to different plots, and wide in application range.
