Went looking for a shovel and had to get help from Google: The shovel in ARK: Survival Ascended is part of the paid Bob’s Tall Tales DLC (specifically the Frontier Adventure Pack). It is not a base-game item and requires the DLC to be purchased and installed to appear in the engrams menu, where it can be unlocked at level 20.

It's a shovel. That's it, nothing to see here.

It doesn’t show in my engrams the shovel

Use to till a crop plot to increase production of crops
