ABSTRACT:
A tine mounting for a rotary harrow has an elongated support and a holder at each outer support end. Each holder has a configured vertical bore that tightly receives the fastening portion of a tine and a central bore that receives a rotary shaft. The mounting is preferably made of a single piece of forged or cast material with the forward side of each holder having an integral screen and a majority of the mass of the material. The support can have an inclined portion that projects from each side of the central bore. The vertical bores can taper upwardly and be multi-sided to conform to a tine fastening portion.
