Removed: No Longer Available
Overgrown Mower was removed from the game files, and is no longer obtainable.
Overgrown Mower was a shortsword that was found in chests inside underground wilderness mini-biomes. It emitted a slow moving ball of damaging energy when swung as well as scattering fast moving Cutter Leaf projectiles.
It was the upgraded version of Undergrowth Trimmer, another shortsword that was found in wilderness mini-biomes.
It was removed when the weapon system was overhauled in update Cheerful Giraffe.
