Advanced resource collector
Immune To vein
A free Weed Eater comes with each Tiberium Waste Facility
Essentially a lightweight combine harvester on a tracked chassis, it is designed for collecting veins from Veinholes and delivering them to the Tiberium Waste Facility for processing into Chemical missile payloads.
The Weed Eater is basically a overhauled harvester, meant to collect the vein appendeges of a Veinhole, and is the only unit in the game that can do this. Weed Eaters have similar armour, health, and speed as a regular Harvester and are required to fuel the Nod Chemical missile.
In Official Guide Book released in Chinese mainland, Weed Eater is translated as "除草机 (weeding machine)", given the fact Tiberium veins spread fast and invasive as weeds.
