Abstract of the Disclosure 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 hill be urged correspondingly for- wardly 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.
