ABSTRACT:
The present invention relates to improvements in trellis systems for supporting growing fruit bearing vines, and in particular, to improvements in the trellis itself wherein cross member secured to a post is fitted with rotator arms at either end thereof, which rotator arms are movable about their mounting point through an acute angle of about 45.degree. to 50.degree., and capable of being secured against inadvertent rotation at a predetermined position relative to the cross arm so as to permit sun to shine on the central area of the vine when the rotator arms are moved downwardly, and to permit harvesting when the arms are upright.
