This Harvester icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,400 icons, all in the same style and quality.
This looks like a drawing of a tractor or a plow of some kind. There is definitely a plow on the front of what ever machinery it is. Sticking out of the drivers side is some sort of attachment that I can't make out.
