Which is a disadvantage of machine harvesting?

• A. Not suitable for vineyards on steep slopes or with limited access
• B. Always yields perfect results
• C. Lowers labor costs in all cases
• D. Is gentler on fruit than hand harvesting

Answer: (A)

Machine harvesting carries a clear drawback in that it isn’t workable in all vineyard situations, especially when the terrain is challenging. These machines are large and heavy and work best on relatively flat, accessible ground with wide, well-maintained rows. On steep slopes, narrow or irregular blocks, or sites with obstacles and limited access, the equipment can’t operate safely or effectively, leading to incomplete harvests or damage to vines and fruit. In practice, this means you can’t rely on machine harvesting for vineyards with difficult topography or restricted access.

Other statements don’t fit the reality of harvesting practices. It isn’t guaranteed to yield perfect results—mechanical methods can bruise berries, miss ripe fruit, or cause inconsistent picking. It doesn’t automatically lower labor costs in all cases because the machines require significant investment, maintenance, and skilled operators. And it isn’t gentler on fruit than hand harvesting; delicate handling is typically better achieved by hand.
