Description
Anyone who’s spent long days on an old International Harvester knows that worn-out seat springs turn every bump and rut into a jarring reminder that comfort matters. When your original seat spring has lost its bounce or snapped after years of faithful service, this replacement spring restores the cushioning you need to stay comfortable during those marathon planting and harvest days.
What You’re Getting
- Heavy-duty conical design that matches original spring performance and mounting
- 3/8-inch wire diameter built to handle years of compression and rebound cycles
- 11-3/4-inch length and 8-1/2-inch base diameter for proper fit and support
- High-carbon steel construction that won’t sag or break under normal farm use
Built for Real Farm Work
This spring fits International Harvester and Farmall tractors that came with the original spring-mounted seat design. Whether you’re running an old Super C for chores around the farm or using that trusty Farmall for hay work and cultivation, this spring restores the original ride quality. These tractors handle everything from loader work to field operations where a comfortable operator seat makes all the difference during long work days.
Made to Last
Farm equipment takes a beating, and seat springs see constant use as you bounce through fields and navigate rough terrain. This spring uses quality steel that’s heat-treated to maintain its tension through thousands of compression cycles. It won’t lose its spring rate like cheaper alternatives that leave you sitting on what feels like a metal pan.
Good to Know
Installation involves removing the seat and swapping springs – usually straightforward on these older tractors. Make sure to support the seat properly while working and check that the spring seats correctly in its mounting points. If you’ve been putting off this repair because of a sore back, you’ll be amazed at the difference a proper seat spring makes during a full day’s work.
