The purpose of this utility model is achieved in that it comprises frame, walking chain, walking chain bogie wheel, ploughshare, guide wheel assembly and control crank, it is characterized in that: the assembling diesel engine and the gearbox of driving coupling with it on frame, chain drive gear with the walking chain engages is set, ploughshare connects tooth bar, tooth bar engagement lifter wheel, lifter wheel connects the gear arm, and the gear arm connects the ploughshare lift control lever by pull bar, and the control stick location-plate is set; The guide wheel assembly is provided with tumbler, and tumbler connects two wheel arms, assembles single guide wheel and dual boot wheel on two wheel arms respectively, and keeper is set on the tumbler.

Assembling chain drive gear in the middle of above above-mentioned two walking chain bogie wheels.

The trapezoidal bent plate of welding on the above-mentioned walking chain.

Above-mentioned dual boot wheel is made of the connection of two butterfly wheel sheets.

The utility model has the advantages that: 1, volume is little, and oil consumption is few, and tractive force is big, easily operation and maintenance.2, traction wheel can be adjusted conversion, is suitable for the different instructions for uses of primary cultivation and intertillage, stability and good homogeneous degree during the raising primary cultivation, and farmland quality is good, the efficient height.3, the trapezoidal bent plate of welding on the walking chain, non-slip, motive force is big, and it is dark to plough, the efficient height.4, can the fine operation that is applicable in land for growing field crops, patch, hillside fields, non-rectilinear plot and the booth.
