Editing Tractor (section)

=== Fixed mounts ===
Some tractor manufacturers produced matching equipment that could be directly mounted on the tractor.  Examples included front-end loaders, belly mowers, row crop cultivators, corn pickers and corn planters.  In most cases, these fixed mounts were proprietary and unique to each make of tractor, so an implement produced by John Deere, for example, could not be attached to a Minneapolis Moline tractor. Another disadvantage was mounting usually required some time and labor, resulting in the implement being semi-permanently attached with bolts or other mounting hardware. Usually, it was impractical to remove the implement and reinstall it on a day-to-day basis.  As a result, the tractor was unavailable for other uses and dedicated to a single use for an appreciable period of time.  An implement was generally mounted at the beginning of its season of use (such as tillage, planting or harvesting) and removed when the season ended.
