- Figure 1
Long, continuous 3.2 km rows in a Pinot gris vineyard in Kern County, California. Long rows are preferred to minimize the number of turns for the continuous operation of mechanical equipment.
- Figure 2
Proper spacing between alleyways will ensure long-machines can turn into rows easily.
- Figure 3
(A) High quality steel end posts and line posts are needed to ensure that the load of fruit and the torque from machines can be handled. (B) Narrow profile steel end posts with spaded ends are preferred in mechanically managed vineyard installation.
