The cultivator is not obtainable at the beginning of Valheim. If you want to get it, start a custom game and teleport yourself onto the farm located in Sonora Valley - Section A by using the map posted on our website (https://www.sailingtheatles.com/2018/03/26). Once there, follow these steps:
1) Kill all enemies until they respawn again 2) Use your shovel 3) Bury items 4) Dig them up with your hand 5) You will now have an airtight room that can be accessed through any wall or window
