If you have a big territory you might need mechanical harvesting since you cannot do it manually since it's too big. And when the territory is small you can manually harvest the products. But since mechanical harvesting has cons like these:
Mechanical Harvesting Cons:
No precise judgment for optimal maturity
No selective harvesting
Not appropriate for crops requiring multiple harvests
May cause excessive damage to fruit and tree/plants
Can be quite expensive for small scale orchards/fields
Manual Harvesting Cons:
Can take a long time
Labor requirements can be a big, and expensive problem, particularly in developed countries.
Possible labor strikes during the harvest period can be a problem for growers.
