摘要：The cultivator shaft is coupled to the tractor's power take-off, and rotates the input pinion of the transmission system. The shaft has a crank similar to that of a brace and bit. The hollow of the crank coincides with the back-balances ends of the blades of the two rows of rotors positioned on adjacent planes on each side of the transmission system. The crank synchronises with the movement of the back-balanced ends of the blades in front of the geometric axle of the shaft. The ratio between the gears of the transmission system is in relation to the number of blades positioned on each operating plane. The cultivator is attached to the rear of the tractor and has a rotor which blades which dig into the soil.
