The Aschen Harvester is an automated farming machine that traverses the skies above Aschen farming planets. Relying on anti-gravity technology to float over entire fields, the Harvester is used to collect the crops by some unknown means when the field it is assigned to is at the peak of growth. The collected crops are stored in one of three large compartments on board, eventually being transported through the Stargate to the Aschen homeworld. The Harvester can also transport other objects through the Stargate, including biogenic weapons, making the Harvester much more than just a farming tool.
The inside of the Harvester has at least one room in which occupants can reside, and underneath the ship to one end of the room is an open balcony where occupants can view out. There is also a lavatory on board, and an Aschen transporter. One of these flying machines was encountered on the Volian homeworld. (SG1: "2001")
