The Case 1840 and Its Place in Compact Equipment History
The Case 1840 skid steer loader was introduced in the early 1990s as part of Case Construction Equipment’s push to dominate the compact loader market. Built in Burlington, Iowa, the 1840 quickly became one of the most popular mid-frame skid steers of its era. With a reputation for mechanical simplicity, durability, and ease of service, it was widely adopted across North America and exported globally. Thousands of units were sold between 1992 and 2001, and many remain in active use today.
The 1840 was designed to bridge the gap between light-duty loaders and larger, more complex machines. Its mechanical drive system, straightforward hydraulics, and robust frame made it ideal for contractors, farmers, landscapers, and municipalities.
Core Specifications and Performance Profile
Typical specifications for the Case 1840 include:
The 1840’s compact footprint and responsive controls made it ideal for tight job sites, while its mechanical simplicity allowed for field repairs without specialized tools.
