Combine Harvester TOP Pro Series 1:20 ScaleA powerful harvester that does the work of 50 men! Every detail of this massive machine has been represented in our scale plastic version. The mower blades extend in front of the cab and move like the real thing (blades are safe and do not actually cut), or it can be trailed behind with the included trailer hitch. Other realistic details include soft tread tires, a movable rotating air filter, a swinging arm that extends, a wheat bin with opening hatch and a viewable engine.
