A cultivator has a row of soil working members mounted on upwardly extending shafts journalled in a hollow frame portion that houses driving connections for the shafts. The working members have tines that are deflectable relative to their shafts, such as supports with hubs that can be interconnected to tine supports by resiliently mounted arms. The hollow frame portion can be fashioned from upper and lower parts that are clamped together with brackets and bearings, for the shafts are held in place by the brackets. A leading soil crumbling member is pivoted to the front of the frame portion by a linkage that allows deflection of the leading member and a setting device can fix that member in place to provide support for the implement. A rear soil crumbling member is pivoted to the rear of the working members and an eccentric driving mechanism is interconnected with the rear member to vibrate same in up and down movements and further work the soil. |
