A free mod for Stardew Valley, by Cat.
This mod lets you collect hay even if your silos are full or you don’t have any silos. It also lets you pull hay from hoppers even if all animal feed locations are full. With its default settings, it will go to your inventory, then to your silos, and finally drop on the ground. You can configure it to not go to the ground if you have no room in your inventory.
If you have a lot of silos or animal feed locations, you can set it to not go to the ground if all the locations are full. This mod has a chance to drop a grass starter instead of hay. The chance to drop the starter depends on the amount you set.
