Hi-Lift Jack Value Guide

Invented in 1905 by A.C. Harrah as the Automatic Combination Tool, the Hi-Lift Jack is a cornerstone of American agricultural and off-road history. Its enduring cast iron and steel construction makes vintage units highly sought after by collectors of rugged mechanical equipment and recovery gear.

What affects the value of Hi-Lift Jack?

• Mechanical integrity of the climbing pins and springs, as fully functional vintage units are more desirable than seized examples.
• Presence of original manufacturer stamps or early production markings from the Bloomfield, Indiana facility.
• Overall condition of the cast iron frame, specifically looking for a lack of stress fractures or excessive pitting from outdoor exposure.

How to Identify Hi-Lift Jack?

• Look for the 'Automatic Combination Tool' branding on early 20th-century models produced before the Hi-Lift name became the industry standard.
• Verify the heavy-duty cast iron and steel components, which should exhibit industrial-grade casting marks and significant weight compared to modern replicas.
• Check for the specific ratcheting mechanism design and climbing pins patented by A.C. Harrah in the United States.
