The mod people usually mean is the Horsch Pack in Farming Simulator 22. It’s commonly mentioned because it can direct drill, fertilize, and handle rolling/mulching-style field work in one setup or very close to it, depending on the implement and crop.

Closest match

  • Horsch Pack : the most likely answer if you want seeding + fertilizing in one pass, and it’s also the one players often point to for the “all-in-one” workflow.
  • SMS Grassland Roller Pack : more specific to rolling/grassland work, so it may fit part of what you described but not the full seed + fertilize combo.
  • Seeding Options : another mod people use to expand seeder behavior, including fertilization-related options.

Why this is probably it

A player discussion specifically says the Horsch pack “has what you are looking for,” noting direct drill, fertilizer, and planting capability, plus some roller/mulcher functionality.

That makes it the best match for a machine you can “seed, fertilize, and roll” with in Farming Simulator 22.

Tiny caveat

There may be a few different mods or tool combos depending on whether you mean rolling after seeding , mulching cover crops , or doing everything in a single pass.

If you want the exact item name from ModHub or the in-game store, I can narrow it down further from the specific machine type you remember.
