587613301 Lawn Tractor Seat Compression Spring Replaces 124181X Spring, Compatible with Husqvarna Seat Compression Spring (2pcs)

What It Is

This compression spring set (2 pieces) supports the seat cushion on Husqvarna lawn tractors, providing the lift and tension needed for operator comfort and seat positioning. It’s designed for riders with a spring-under-seat mechanism, not zero-turn mowers.

Fitment & Compatibility

• OEM Reference: Replaces Husqvarna part number 587613301 and older 124181X. Cross-check your tractor’s manual or existing spring for these numbers.
• Brand Fit: Direct fit for many Husqvarna, Poulan Pro, and Craftsman lawn tractors with a single-post seat mount. Not universal—avoid on Ariens, John Deere, or Cub Cadet unless cross-referenced.
• Measurements: Spring is approximately 2.5 inches long, 1 inch outer diameter, with closed ends. Measure your old spring’s length and coil count (typically 8-10 coils) to confirm.
• What to Check: Look at your seat mounting bracket. If it uses a single center stud with a nut and washer, these springs likely fit. If your seat has dual springs or a gas shock, they won’t.

Key Things to Know

• Quality: These are basic steel springs, not heavy-duty or coated. Expect standard wear—rust may appear after a season in wet conditions.
• Installation: Easy—remove seat, swap springs (no tools needed beyond a wrench for the seat bolt). Takes 5 minutes.
• Common Gotcha: These are sold as a pair (2pcs). You only need one per seat unless your model uses two springs side-by-side. Check your current setup before opening.
• Fitment Risk: Some users report these are slightly shorter than OEM, causing a softer seat feel. If you prefer a firmer ride, look for a stiffer aftermarket alternative.

Should You Buy It

If your Husqvarna or compatible tractor’s seat sags or lacks lift, this $9.85 spring set is a cheap, quick fix for basic comfort restoration. Skip it if you need a heavy-duty spring for rough terrain or a non-Husqvarna brand—measurements and fitment are too narrow for universal use.
