2. Reverse Rotation Anatomy: How a Stone Burier Gearbox Works<\/h2>\n

The “Reverse Rotation” function is not merely a direction of travel; it is a fundamental kinetic requirement for stone-burying machines. Standard tillers rotate with the direction of travel (Forward Rotation), which can cause the machine to “run away” on hard ground. Conversely, a stone burier rotor rotates counter to the direction of travel. This creates a powerful lifting action that pulls soil and rocks upward against a sifting grate.<\/p>\n
