Seasons, built by Realismus Modding, is one of the few mods that genuinely changes how Farming Simulator 19 plays. It’s on ModHub as FS19_RM_Seasons.zip and once it’s active, it touches weather, crop growth, the economy, vehicle wear and animal care all at once. This isn’t a small tweak mod, it’s a full system replacement, so before you drop it into a career you already love, it helps to know exactly what changes and what it expects from you.
The short version: Seasons turns the calendar into something you actually have to respect. Plant too early or too late and crops suffer. Ignore winter and you’ll be stuck. Mix in other mods that also touch weather or growth and things break in ways that are hard to diagnose later.
What Seasons actually changes
Once active, Seasons replaces or heavily modifies several core systems:
- Weather becomes tied to the season, with realistic temperature swings, rain patterns and snow in winter instead of the vanilla random weather.
- Crop growth now depends on temperature and moisture, not just a fixed growth timer.
- The economy shifts with supply, demand and season, so prices for the same crop move up and down depending on the time of year.
- Vehicle maintenance gets more involved, with wear tied to actual use over the seasons rather than a flat decay.
- Animals get season-aware needs, and this extends to cattle, pigs, sheep and chickens, plus horses as a steady side income if you keep them.
None of these are optional add-ons within the mod. They come as a package, which is exactly why it conflicts with other mods doing similar jobs.
Planting and harvesting on a schedule that matters
In vanilla Farming Simulator, you can plant more or less whenever and the crop will grow on its own timer. Seasons throws that out. Crops need to go in the ground early enough to germinate, but not so early that cold kills the seedlings, and not during a stretch that’s too dry for them to establish.
Harvest timing matters just as much. Leave crops standing too long into autumn and rain will soak them, dropping quality and your payout. The practical habit to build is: check the season and weather forecast before you plant, and plan your harvest window around the first real autumn rain, not after it.
Winter is a full season, not a pause
In vanilla play, winter barely exists as a concept. Under Seasons it becomes its own chunk of real work. Snow needs clearing from your yard and access roads, and this opens up forestry work as a viable income when fields are frozen and nothing is growing. If you’ve never bothered with logging equipment before, winter under Seasons is the reason to start.
Livestock through the cold months
Animals don’t just sit in a barn eating the same feed all year. Cattle, pigs, sheep and chickens all need their care adjusted for the season, and horses in particular are worth keeping around because they give a steady, reliable income that doesn’t swing as hard as crop sales do. Treat winter as the season where your animal operation carries the farm while fields rest.
Map support is not guaranteed
Seasons depends on the map supporting its systems properly, especially for things like snow-related contract work. Not every map was built with this in mind. The mod’s own change notes are blunt about it: a map may simply not work correctly with Seasons until its author updates it to add that support.
Before you commit a save to a specific map, go check that map’s own mod page for a note about Seasons compatibility. If there’s no mention of it, assume you’re taking a risk, not that it’ll just work.
Don’t run it alongside other weather, growth or animal mods
Because Seasons takes over weather, crop growth and animal systems completely, running it next to any other mod that also changes those same things is asking for conflicts. This isn’t a new rule invented for this version either, it’s the same warning the Realismus team gave with their earlier release for the previous game. If a mod touches weather, growth timers or livestock behavior, it’s a candidate for conflict and should be left out of a Seasons save.
Start a new career, don’t bolt it onto an old one
The safest way to run Seasons is to begin a fresh career from the start with the mod already active. For the earlier version of this mod, the authors were explicit that turning it on inside an existing save was not something they officially supported. Treat that guidance as still applying here: if you want to try it on a save you already care about, make a copy of that save first and understand you’re doing it at your own risk, not with any promise it’ll behave.
Starting clean avoids a whole category of weird bugs where the game doesn’t know how to reconcile existing crop states, animal data or seasonal progress that was never tracked in the first place.
Read the in-game help before you touch a field
Once the mod is active, Farming Simulator 19’s help menu gets its own dedicated Seasons section. This is genuinely the first thing to open before you plant a single seed. It covers the specifics of how growth windows, temperature thresholds and seasonal transitions work in more detail than any general guide can, and since Realismus tunes these numbers, the in-game text is the authoritative source for your exact setup.
Questions people ask
Can I add Seasons to a career I already started?
You can try, but the mod's earlier version wasn't officially supported for this and the same caution applies here, so copy your save first and expect possible issues.
Why does my map not work right with Seasons?
Seasons needs the map itself to support its systems, particularly for snow related contracts, and some maps haven't been updated by their authors to add that support.
Can I run Seasons with other weather or crop growth mods?
No, Seasons replaces those systems entirely, so running another mod that also changes weather, growth or animals will likely cause conflicts.
Where do I learn the exact planting windows for my crops?
Check the Seasons section added to the in-game help menu once the mod is active, since it has the specific temperature and timing details for your setup.
