WF - 1 Digging and fertilizing machine is a type of farmland operation tractor with a complete set of four-wheel, has reasonable design, compact structure, complete functions, multiple-usage, reasonable power matching, convenient in operation and maintenance, price moderate, etc. Rotary tillage, ridging, fertilizer applying and ridging up two ridges together can be finished in one time. It can operate in sand soil, half sand soil. (sticky soil and weedy fields will affect the results). Has the advantage of high work quality, time and labor saving, good maintainability, etc. During the process of test, we obtained the good results based on different operation soils. The test proved that it greatly improved the labor efficiency and reduced the labor intensity.
  This machine is mainly suitable for digging and fertilizing of tobacco planting. This machine is mainly suitable for tobacco, sweet potato, peanut planting of ridging. The reasonable working environment is plain and hilly regions. In sandy loam and half sandy loam or good operation regions the effect will be better. The results may be slightly worse if working in the wet clay or drought, water-logging earth.

Since 2012, our company developed the first generation of prototype, through years of research, design, trial production and a large number of field experiment, combined opinions of agricultural experts and grow agronomic of flue-cured tobacco, sweet potato, peanut and other crops and through repeated Experimental Investigations in different regions, different geological conditions, we finally fixed this design. In the production of large area, the effect is very good and warmly welcomed by agricultural experts and farmers friends, tobacco farmers.
The operation:  
Confirm the row spacing before working and adjust the equipment. You should pay attention to the following issues:  
1, Ready for use: check each parts of the device connections, tighten up all bolts on it, ensure that all working parts must be flexible rotation.  
2, In wheat stubble fields: first gear should be adopted, you can also use second gear if less weeds in winter farmland to increase the production efficiency.  
3, Make sure not too much weeds on the coulter while working, otherwise will increase the consumption of tractor power and its parts. Stop when you remove weeds ensure safety in production.  
4, It can cultivation back and forth and doing annular operations according to landform. Left 2-2.5 m for its head to turn around while working so as to avoiding ridging plow knife shaft damage raised from excessive torque.  
5 Frequently check the distributing status, stop and adjust immediately to the moderate amount if fertilizer consumption is too big or too small.
