Front Idler EX60-1
Production introducton:
The idler picks the "used" track back up, and returns it back to the drive sprocket in the front. This is why an early term for a tracked vehicle was a "track-laying machine" (not to be confused with railroad track laying equipment). Transporting vehicles over muddy ground often required planks or logs to be placed along the track. In the later 19th century, inventors figured out a way to make a rolling machine that would lay its own plank road wherever it went, negating the need for farmers to lay down logs in order to traverse muddy areas. Other benefits were discovered later.
