How to get seeds with the Threshing attachment in Icarus Update
So you’ve been whacking plants all over Icarus, stuffing your inventory with crops, but ever since the update, getting seeds isn’t as simple as slicing up the greenery. That’s because the devs made seed collection an opt-in system, which honestly makes farming feel more rewarding and less like an inventory management nightmare. If you’re at Tier 3 and ready to take farming into your own hands, the Threshing Attachment is your ticket to a smarter seed haul.

Getting the Threshing attachment
Hit Tier 3 to access this upgrade. Unlock Tool attachments in the Tech Tree. Then, you can craft a Threshing attachment at an Alteration Bench. To put it together, you’ll need a mix of Tier 3 materials like steel ingots, epoxy, and charcoal ore. Yeah, that means it’s a bit of a grind, but once it’s in your hands, it’s totally worth it. This thing turns your basic sickle into a hybrid tool that doesn’t just harvest crops - it grabs the seeds too.

Attaching it to your sickle
Head to your alteration bench and slot the Threshing Attachment onto your weapon. It doesn’t change the way the sickle swings or feels, but once it’s equipped, every swipe through wild plants or crop plots comes with a solid chance of dropping seeds along with your regular harvest. No fancy animations, just results.

Harvesting with your upgraded sickle
Time to hit the fields. Find a patch of wild wheat, reed flowers, or any crop that you’ve planted. Start swinging, and you’ll notice the difference right away. Instead of just picking up fibers and plants, you’ll start scooping up seeds too - sometimes in big batches depending on the crop. It’s smooth, efficient, and honestly kinda satisfying to see those seed icons popping into your inventory. Unlike the Seed Extractor, you don’t have to wait or process anything. It’s instant seed collection while you’re already gathering resources.
When to use the Threshing attachment
This upgrade shines when you’re not interested in crafting fertilizer or grinding down veggies. It’s the perfect mid-to-late game tool when you want seeds but don’t want to mess with extra machines. You can even take it into prospects with lots of natural crops and just go wild harvesting everything in sight.
Comparing it to other seed tools
The Seed Extractor is slow and stationary. The Progenative Fertilizer takes planning and comes with trade-offs. The Reaper Sickle is awesome but costs exotics and has to be unlocked through the workshop. But the Threshing Attachment? It’s the balance point. It’s upgradeable, reusable, and doesn’t tie you to one spot. It’s not the flashiest tool in the game, but if you want reliable seeds without a big investment, this is where it’s at.

Boosting your harvest with talents
Want even more seeds? Pair your upgraded sickle with the Seed Master and Prolific Crop talents. These give you bonus seed yields from both wild and farmed crops. You’ll need to spend a few talent points in the Cooking and Farming tree, but it stacks perfectly with the attachment’s power. Throw in a few good crop plots and you’ll be churning out seeds like a machine in no time.
Things to keep in mind
Don’t forget that not all plants give the same amount of seeds. Some crops are stingy even with upgrades, so experiment a little to figure out which ones are most efficient. Also, make sure your sickle is fully repaired before you head out - nothing kills the vibe like your tool breaking mid-harvest. And if you're farming indoors, keep those plots fertilized and watered to get the most out of your efforts.
The Threshing Attachment is a low-fuss, high-reward upgrade that fits perfectly into Icarus’s new seed system. It gives you the freedom to collect seeds while you harvest, without dealing with extra machines or crafting steps. Upgrade it, use it, and enjoy never running out of seeds again.
