This is an actual reupload and fixed work of Aedonthorn's Hoe Radius mod on Nexus. All credits goes to aedenthorn.

As of version 0.221.12 (n-36) of the game, it works perfectly fine.

Info

This mod allows you to modify the size of the land affected by the hoe by holding down an optional modifier key (default: Left Alt) and scrolling with the mouse, or by pressing one of two customizable hotkeys (default: disabled).

You can also adjust the increment values and hotkeys in the config file.
