Cultivation can be performed instead of the arduous plowing, but only for some plants: grains and sunflower; optionally corn. As a rule, if possible, it is better to carry out cultivation INSTEAD of plowing – it is faster, less-powerful machines are required to operate the cultivators, and the machines are decently priced (and often have a built-in seeder / fertilizer spreader). Plants for which cultivation is sufficient: wheat, barley, oats, sunflower, corn (with a -15% yield loss without plowing).
Tip: the vast majority of cultivators have an in-built seeder and/or fertilizer spreader: you can carry out two or even three actions in one go!
Tip 2: Cultivation does not affect yields: after plowing, you do not have to cultivate the soil.
Tip 3: You can find cultivators in the shop under the following categories: Cultivators, Power/Disc harrows, and Planters/Seeders (here you will find the machines that plant and cultivate at the same time).
Tip 4: Farming Simulator 19 introduces a new shop category: Disc/Power harrows. They are also cultivators, but of a different design. They are characterized by: higher work speed, lower price, lower power requirement of the tractor. However, they do not combine the features of seeders/planters.
