About Wagner
The Wagner brothers of Oregon were early developers of articulated four-wheel-drive agricultural tractors. Their work grew out of machinery experience in logging and mining.
- Beginning
- Industrial machinery roots from 1922; farm tractors in the 1950s
- Founder / origin
- Wagner brothers, Portland, Oregon
- Known for
- Large articulated four-wheel-drive tractors
- Sale / later history
- A late-1960s John Deere arrangement and its restrictions ended the farm-tractor chapter
History and legacy
Wagner adapted heavy machinery experience to agricultural traction. The archive describes a small John Deere purchasing arrangement and a subsequent non-compete restriction that curtailed Wagner tractor production. This was a particular agricultural-market outcome; it should not be expanded into unsupported claims about every Wagner-branded industrial operation.

Index power values can include estimates derived from belt or PTO power. They are identified on each model card and are not interchangeable with a measured engine rating. Model years and missing values follow the source index.
