Just like in every other game from the series, your machines in Farming Simulator 19 must have their tanks filled with necessary goods. A seeder needs seeds, fertilizer spreader needs fertilizer. Fill a sprinkler with herbicides to get rid of weeds.
To fill your machines with the goods, attach them to a vehicle (unless they are self-propelled), buy the right pallet in the Shop, and drive the vehicle with the machine to that pallet. You can't refill the tanks anywhere you want to, this is possible only near the Shop. Check a few tips that should help you with this process.
Transporting by using machines
Some machines can be unloaded right after you fill them. In a lime spreader's case, everything will be unloaded on pallets and placed near the machine. You can use this form of transporting fertilizer that you want to use in, i.e. a seeder.
Transporting goods on pallets is a good idea. Buy a loader, front loader to your tractor with an attachment for pallets or a forklift, and load goods on any of your trailers. Low bed trailers or trailers for bales are great for transporting pallets.
Transporting in a dumper trailer
You can pour the content of pallets straight into a dumper trailer - this method will probably be the most popular among the players. This option allows you to quickly and safely transport large quantities of seeds/fertilizers and unload them anywhere you want, even on the ground (on your parcel).
The problem here is that you can't load goods on a dumper trailer straight from the ground. If you scattered them on the ground, you have to load goods from above, by using a shovel attached to any of your loaders. The disadvantage is that you can't transport liquids in a dumper trailer.
Auger wagons are also a good way of transporting fertilizer and seeds, provided that you have enough money to purchase any of them. These wagons are easy to transport. Thanks to a retractable pipe, they can fill any machine. Seed Runner 3755 XL, the cheapest wagon, has the capacity of 8,000l and costs $20,000. This is plenty enough - you will be able to work away from the shop for a long time.
