330105 Dethatcher Rake Spring, Springs for Arnold 16 Inch Dethatching Mower Blade, Power Blade and Mastercraft Thatcher Blade, Spring for Dethatching Rake Blade, 6 Pack

What It Is

This 6-pack of replacement springs (part 330105) is designed for use with dethatching rake attachments—specifically the Arnold 16-inch dethatching mower blade, Power Blade, and Mastercraft thatcher blade. They provide the tension needed to keep the tines engaged with the lawn surface during dethatching.

Fitment & Compatibility

• Primary fit: Arnold 16-inch dethatching mower blade (model 490-110-0006), Power Blade, and Mastercraft thatcher blades.
• What to measure: Each spring is approximately 1.5 inches long with a 0.5-inch coil diameter. Check your existing spring length and coil count—if yours are shorter or longer, these won’t work.
• Deck size: Works with any deck size that uses the above blades, but not universal. Confirm your blade has spring mounting holes spaced about 2 inches apart.
• OEM vs aftermarket: These are aftermarket replacements. If your original springs are from a different brand (e.g., Agri-Fab, Yard Tuff), verify the hook ends and tension match.
• Avoid if: Your dethatcher uses a different attachment system (e.g., tow-behind, electric) or uses solid tine bars instead of individual spring-mounted blades.

Key Things to Know

• Quality concerns: At 3.6 stars, some users report springs losing tension after a few uses or breaking under heavy thatch. Expect them to be functional but not heavy-duty.
• Installation: Easy—just unhook old springs, hook new ones onto the blade and frame. No tools needed, but wear gloves; the hooks can pinch.
• Common gotcha: The springs may be slightly stiffer or looser than OEM. If your dethatcher bounces or tines don’t dig in, you may need to adjust your mower deck height or replace all six at once for even tension.
• Pack size: 6-pack is enough for one Arnold 16-inch blade (uses 6 springs). No extras included.

Should You Buy It

Buy this if you need a budget-friendly, quick fix for a worn-out spring set on an Arnold, Power Blade, or Mastercraft 16-inch dethatching blade, and you’re okay with replacing them every season or two. Skip it if you need heavy-duty, long-lasting springs for commercial use or if your dethatcher uses a different blade system.
