Hello,

this is a combine harvester used to harvest grain. Please consider taking a look at my Claas Combine Harvester or my John Deere Combine Harvester. They are a lot better.

Combines have a reel that holds the grain while a cutterbar cuts the grain plants off.
Over a twin auger and conveyor belts the grain is transported inside the vehicle where one or more threshing drums hit the grain out of the plants. To seperate grain from straw there are several vibrating sieves and a fan that blows out particels lighter than the grain.
The air pump for the blower is the black thing on the top right of the vehicle.
Needless straw is ejected at the back and the precious grain is stored in a tank right behind the driver's cabin.
For unloading the grain the combine harvester has a tube with a transfer auger in it.

Enjoy!
