What is a Rotavator?

Rotoravator is an attached working tool of a tractor, and is an agricultural machine that cuts the soil by rotating several blades connected to the rotary shaft using the PTO rotational power of the tractor.
It is used for soil preparation for sowing and transplantation. If plows help the soil circulation by plowing the ground, the rotorbater grinds and crushes the soil into small chunks, so fertilizers are well mixed in the ground, making it an essential agricultural machine in modern agriculture.

In English, it is commonly known as ROTORVATOR, CULTIVATOR, ROTARY HOE, ROTARY TILLER, and in Korea it is also called ROTARY as a short. Human have cultivated crops for thousands of years and spent most of the time plowing land. A modern powered rotary hoe was invented in 1912 by Australian inventor Arthur Clifford Howard. 
Since Howard (1893-1971) made a cultivator equipped with a motor, he has taken a step closer to modern cultivation methods.

Depending on the usage of the rotavator, it varies from small, medium, and large rotavator to folder-type rotor bater capable of cultivating a large area.
Depending on the horsepower of the tractor, there are from a small 20-horsepower range to a large rotorvator with more than 200 horsepower.

Various companies around the world produce various rotavators.
It is produced by foreign brands such as MASCHIO in Italy, CELLI in Australia, and various companies such as WeCan Global, Woongjin, Youngjin, Greenmax, and Korean chain in Korea.

With the recent enlargement of tractors, more than 100 horsepower tractors are being distributed to farms in Korea. As a result, rotorbaters are also on the rise in size. In line with this trend, WeCan Global has the technology to meet the diverse needs of consumers, from small rotorbatters with 15 horsepower to ultra-large machines with 300 horsepower. It has a product line and is moving forward as a leader in the domestic rotor-vator market.


  1. 1.

    The upper cover is double-jointed, so there is no interference or distortion between both side plates, and the round can be preserved even after long use.

  2. 2.

    Special seals are used on the drive shaft to block water and other foreign substances from entering the bearing, improving the bearing durability.

  3. 3.

    The blades were redesigned and specially arranged to fit the soil of Korea and Asia to fit any crop planting system, thereby significantly reducing the load on the machine.

  4. 4.

    Rotoravator shafts are flange-type and are designed to be suitable for hard soil and are suitable for long-term use due to the ideal wear of the blade.

  5. 5.

    With the development of the side gear type idle gear shaft, the durability of the side gear has been improved by drastically breaking away from the existing welding structure and improving the prefabricated structure.

  6. 6.

    It is now possible to freely select the working speed by adopting a gear-type transmission for medium and large horsepower.

  7. 7.

    The Gleason-type spiral bevel gear reduces noise while driving and increases the contact area of the gear to improve durability.

  8. 8.

    By selecting a hypoid gear for a small rotor-vator model, the noise is reduced, the contact area is expanded to improve durability, and the center point of the pinion shaft is moved down and parallel. It has reduced the angle deformation of the universal joint and improved the durability of the universal joint.

  9. 9.

    By developing a rotor shaft with the ability to block foreign substances, the ability to block foreign substances instead of the existing dust cover function has been improved and durability has also been improved.

  10. 10.

    By developing the automatic tensioning device of the chain rotavator, tension can be adjusted automatically and the durability of the chain and sprocket has been improved.

  11. 11.

    By developing a hydraulic cylinder for a mobile rotor, it is now possible to control left and right movement through simple lever operation in the tractor seat.

  12. 12.

    By developing a three-point link mast, the shape of the upper cover is less changed, the load is less, and durability is improved.

  13. 13.

    By improving the center distance of the right side plate of medium and large horsepower, the error was alleviated, and the stability of the rotor was further improved.

  14. 14.

    As the work width of the rear cover is widened, workability is improved, and a bending structure is selected to increase resistance to external force, thereby improving a problem of shape deformation.
