ABSTRACT:
A cultivator has a frame normally carried on the back of a tractor and pulled in a predetermined direction along the ground. A plurality of tines extend downwardly from this cultivator and penetrate the ground. Each tine is pivotal about a respective axis perpendicular to the direction of travel and parallel to the ground and is biased into a normal central position by means of a respective hydraulic actuator. The cylinders of all of the hydraulic actuators are connected together in a closed network so that if one tine is forced backwardly the other tines will be urged correspondingly forwardly and vice versa. In addition each such tine, which also may be mounted on a parallelogrammatic linkage, may carry a V-shaped backwardly extending blade increasing the mixing and aeration effect of the cultivator.
