1 GFV - 120 type rotary tillage ridging fertilizer applicator is a type of farmland operation tractor with a complete set of four-wheel, has reasonable design, compact structure, complete functions, multi-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.
Since 2008, 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.
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.

The working principle: The Power passed to the clutch's gearbox through output shaft of the tractor, then via a universal joint drive shaft to the rotary tillage ridging fertilizer applicator primary transmission, via the drive shaft to the secondary transmission, finally through the secondary transmission to rotary knife roller, make the knife roller two-way install ridging knife forward quickly as a rotation movement, automobile lift the soft soil after the rotary tillage, ridge into proper height, width ridging and get the efficient, accurate and reliable effects.
The installation of rotary knife of ridging installed on the roller rotary tillage blade is in accordance with its center. Both sides of the coulter all reverse assembled so the rotation movement can throw away the soil of ridge top.
    Fertilization structure: install sprocket on the spine shaft via secondary transmission. Then the chain drive special fertilization gearbox, via small chain wheel to the rotating propeller, the fertilizer will comminute the two bins and the fertilization tube will broadcast in right ridging depth.
    This machine can finish the whole process of rotary tillage, fertilization, ridging in one time when moving forward.
