This is a Harvester icon. We've made it in iOS style, first introduced in iOS version 7 and supported in all later releases up until now (at least iOS 11). This style is based on thin two-pixel lines and is optimized for 50x50 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 12,900 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.
