摘要：
A tine harrow has a plurality of harrow tines mounted on and downwardly depending from a harrow frame. The tines are configured to be moveable between a lowered position and a raised position, and at least one tine lowerable or raiseable to a different relative position in relation to a surface of a field than others of the tines. The ability to lower and raise individual tines or rows of tines to different positions in relation to a surface of a field provides more effective response of the tine harrow to changing land conditions. The positions to which individual tines or rows of tines are lowered or raised may be selectively set to further enhance effectiveness of the response of the tine harrow to changing land conditions.
