Requirements and challenges
Traditional vegetable farms in the Loire Valley are based on bed cropping, in open field or under cold plastic greenhouse. More than 60 kinds of vegetables are grown and the pilot area requires 20 workers for an area of 70 ha to cultivate salads, lamb lettuce, leeks, baby-leaf salad, carrots, and in one year, several (3-5) crops are produced at the same place. As a result, many kinds of tasks must be managed on different vegetables, and many tools must be available at any time, while several passes of tractors damage the soil and cause severe compaction. That is the reason why, most often, old tractors are used with always the same tool: tools are not uncoupled.
