A lot of the issues currently are related to the mechanical handling of the fruit. It's very important not to bruise or damage the product. Buyers generally have strict rules on exactly how the fruit is picked, e.g., how much stem is still attached to the fruit, for both weight and quality reasons.

Other issues arise if the orchard is on uneven ground, or their are irrigation lines in the way.

Certainly not insurmountable, but not easy. Then there's the distinct problem of adoption.
