David Brown Legacy:
David Brown was a renowned British tractor manufacturer known for robust and reliable machinery, often with innovative features for their time. The company was eventually absorbed by Case IH.
1490 Placement:
The 1490 was part of David Brown's '10 Series' and represented a mid-range to higher-horsepower offering, designed for general-purpose farming and heavy draft work.
Production Years:
The 1490 was primarily produced in the late 1970s and early 1980s. The manual should cover this specific production run.
