摘要：
A simplified spike tooth harrow includes an apertured bracket pivotally connected to the fore-and-aft connecting strap extending between the tine bars. The bracket adjustably supports a tine bar from the strap. A pin selectively secured in one of the apertures contacts the strap to set the working angle of the tines on the bar when the harrow is operated in the field. A chain or link connected to the bracket at a location offset from the bracket pivot suspends the harrow from an upper drawbar assembly which is movable vertically between field-working and transport positions. When the drawbar assembly is raised to the transport position so the harrow is out of ground contact, the bracket pivots so the pin is offset from the strap and can be easily and quickly removed from the aperture and reinserted in a different aperture to change the tine angle.
