Why Removing Scag Blades Matters

Blades are the cutting heart of any mower. Over time, they dull, bend, or wear down after extended use. Removing and maintaining them properly ensures:

  1. Cleaner, more even cuts across your lawn.
  2. Less strain on your mower’s engine and deck.
  3. Extended lifespan for your spindle and belt system.
  4. Improved fuel efficiency and operational safety.

Scag mowers, known for their heavy-duty construction and performance in both residential and commercial mowing, demand proper maintenance to keep performing like new.

How to Remove Scag Mower Blades (Step-by-Step)

Step Action Explanation
Step 1 Locate the Blade Bolt Locate the bolt in the center of the blade, which fastens it to the spindle assembly. This bolt is usually located in the center of each blade.
Step 2 Lock the Blade Use a wood block or the blade lock tool to prevent the blade from turning while loosening the bolt.
Step 3 Unscrew the Bolt Turn the bolt counter-clockwise with a ratchet or impact wrench. Note the order of spacers/washers for correct reassembly.
Step 4 Pull Off the Blade Carefully pull the blade off the spindle shaft. Handle cautiously as dull blades can still cut.
Step 5 Check and Clean Inspect the spindle area and blade surface for wear, rust, or cracks before reinstalling or sharpening.

Tips for Blade Maintenance

Once the blades are removed, you can clean them with a wire brush and inspect the edges. If the blade is too worn or has cracks, it’s best to replace it with a genuine Scag replacement blade. OEM parts ensure that your mower maintains balance, avoids vibration, and continues to deliver the same precision cuts that Scag mowers are known for. Here are a few quick tips:

  • Always torque bolts to Scag’s recommended specifications.
  • Replace blades in pairs to maintain deck balance.
  • Never install aftermarket blades that can compromise the mower’s integrity.
  • Clean under the deck regularly to avoid the buildup of debris.

When to Replace Instead of Sharpen

If you notice deep chips, bending, or thinning of the blade metal, sharpening might not be enough. Replacement is safer and more efficient. Using genuine Scag OEM blades ensures optimal compatibility, long-lasting durability, and smoother operation.
