1. Fixed

  Fixed dozer tractor fixed at right angles to the longitudinal axis. The main features are simple in structure, easy to manufacture, durable, and low cost. General agricultural bulldozer dozer device mostly with fixed soil knife blade angle majority can be adjusted to control the depth of soil shovel knife easy job, usually in the back of the site is also fitted dozer limited slip deep dish, so dozer can control certain soil depth cut jobs, prevent soil cut too deep causing overload or stall.

  2. Rotary

  Rotary cut soil bulldozing eradicate angle can be adjusted, but also rotation angle in the horizontal and vertical directions, for lateral transverse slope bulldozing and bulldozing. Its main feature is that in the ravines, complex terrain depression sudden ups and downs still has good adaptability, but not too small rotation angle (horizontal rotation angle greater than 25 ° a 30 °, vertical rotation angle should not be less than 10 °, otherwise, would not achieve the thrusters and transverse push effect adjustment mechanism is more complex due to the rotation, ramp operations, is inclined blade, blade withstand lateral pressure in Incline when large, easy to swing and cause locomotive deviation. To continue to pull to manipulate the joystick manipulation more difficult. At present, the project uses more rotary bulldozer dozer device, while still stationary agricultural bulldozer bulldozer majority.
