What's the difference between a disc plough and a disc harrow?

   The main difference between a disc and a disc harrow: 

   一. Different objects and functions of machines and tools: disc ploughs are mainly used for ploughing the 

cultivated land, while disc harrows are used for ploughing the cultivated land.

   二.The disc plough is a three point suspension type connected with the locomotive. The disc handle has large

traction type and small suspension type.

     三.The structure of the machine and job stress is different: the disc plough is like (or is) on the three-

point suspension furrow plough installation the location of the plow zinc, to install two to a number of digging

the discplough body and plate component structure, balance the lateral pressure of the tail wheel, and the devices

work units under the lateral pressure big disc harrow set by the traction frame, rake plane and symmetric multiple

disk groups underthe harrow frame (multichip disc wear on a square shaft for a group of composition, stress relative

equilibrium when working）.

   四.Different structure, the main working parts and devices: due to the grave, digging the ground soil and 

performance requirements higher, disc plough body structure strength of the demand is higher, the disc plough 

disc spherical concavity big (small curvature radius), disc blade thickness in 0.5 1 mm,blade Angle is 12 

degrees commonly, disc type work, disk plane and direction at 40- 45 degree Angle, and the vertical plane into

15 to 25 degrees Angle; in addition to a certain strength, the disc is mainly good wear resistance. The spherical

concave of the disc is relatively small (the radius of curvature is large).The thickness of the disc edge is 

0.3-0.8mm.
