PG9 - Cool tractor and combine harvester at work

The green combine harvester has gathered a grain crop from the field. Inside the combine, the grain is beaten and shaken loose from the straws of grain. Then the grain is fed into a tank while the remaining grain straws are blown out behind. The combine stands still while the grain is transferred to a trailer that will take it in to the farm where it needs to be dried. Two rabbits in front of the combine must get away before the machine starts moving again. A pheasant in front of the tractor has to get back on its wings before the tractor starts again. Some of the 39 puzzle-pieces are shaped like rabbits, dogs, tractor and pheasant. This is a puzzle for all who loves tractors and big machines.
