Abstract
A harrow is provided having an elongate tool bar mounted on wheels for movement in a forward direction perpendicular to the tool bar. A plurality of harrow elements are mounted on the tool bar to extend generally rearward therefrom. A pair of support arms are pivotally mounted on the tool bar at a first end and mount each harrow element on a second end towards a rearward end of the harrow element. A hanger is connected between the support arms and the harrow element towards a forward end of the harrow element for suspending the harrow element therefrom. A plurality of tines are mounted on the harrow element such that the angle of the tines relative to the ground may be adjusted. A coupling connects between the hanger and the tines such that the height of the front end of the harrow frame is adjusted in response to tine angle adjustment.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
