You asked, and I delivered! Vanilla Excavators is a shovel alternative to Vanilla Hammers.
This mod was designed on top of Vanilla Hammers. All mechanics are very similar, so they have identical configuration systems and materials.
DynaGear can be used to add new Excavators based on custom materials.
Nether Things has 3 new Excavator materials based on their content!
Vanilla Excavators is GPLv3. You are free to use it as you wish.
Thanks to Yoghurt4C for the textures, and thanks to everyone who helped improve the original Vanilla Hammers.
