Loader attachments for tractors date back to the 1920s, and most of these early attachments were operated by cable. The bucket was raised and lowered vertically, and dumped by releasing a trip. Though powerful diggers, these machines were frontheavy and topheavy, and visibility to the bucket was a challenge. This is a Cat D-6 with a Trackson T-6 Traxcavator.

Four examples of early crawler loaders illustrate how these machines evolved in the mid-20th century. All images are from the HCEA Archives.
