Cultivator with screening device |
摘要 |
A cultivator having rotatable soil-working tines on supports has a screening element pivotally connected to the front of the frame to extend downwardly near the supports. Springs bias the screening element to a position adjacent the tines to prevent damage by stones encountered during operation. Adjustment members permit the vertical adjustment of the screening element relative to the tines.
