How to Change Blades on a Bush Hog

Changing blades on a bush hog (rotary cutter) might seem daunting, but with the right tools and approach, it's a manageable task. This guide will walk you through the process safely and efficiently. Safety is paramount, so always prioritize your well-being throughout this procedure.

Before You Begin: Safety First!

Before even touching your bush hog, take these crucial steps:

Essential Safety Precautions:

• Disconnect the PTO: This is the most important step. Ensure your tractor's PTO (Power Take-Off) is completely disengaged and the tractor is turned off. Don't just rely on the PTO switch; physically check the shaft to ensure it's not spinning.
• Secure the Bush Hog: Use wheel chocks to prevent the bush hog from rolling. This prevents accidental movement during blade changes.
• Wear Protective Gear: This includes safety glasses, work gloves, and sturdy boots. Consider a face shield for added protection from flying debris.
• Work in a Well-Lit Area: Ensure you have adequate lighting to clearly see what you're doing.

Tools You'll Need:

• Socket Wrench: The correct size will depend on your bush hog model. Consult your owner's manual.
• Hammer: A standard hammer will suffice.
• Wrench (if needed): Some bush hogs may require a wrench to loosen or tighten blade bolts.
• Penetrating Oil (optional): This can help loosen stubborn bolts.
• Owner's Manual: Always refer to your bush hog's owner's manual for specific instructions and torque specifications.

Step-by-Step Guide to Changing Bush Hog Blades:

1. Removing the Old Blades:

• Apply Penetrating Oil (optional): Spray penetrating oil on the blade bolts to help loosen them. Allow it to sit for a few minutes.
• Unscrew the Bolts: Using your socket wrench, carefully unscrew the bolts securing the blade to the cutter head. Work slowly and methodically to avoid stripping the bolts.
• Remove the Blades: Once the bolts are removed, carefully remove the old blades. They might be heavy, so be prepared to support their weight.

2. Installing the New Blades:

• Inspect the New Blades: Before installing, carefully inspect the new blades for any damage or defects.
• Align the New Blades: Ensure the new blades are properly aligned with the cutter head. Refer to your owner's manual for specific alignment instructions.
• Secure the New Blades: Insert the new blades into place and tighten the bolts using your socket wrench. Do not overtighten. Refer to your owner's manual for the proper torque specifications.

3. Final Checks:

• Tightness Check: After installing the new blades, double-check that all bolts are securely tightened.
• Blade Rotation: Visually inspect that all blades are rotating in the correct direction. This is crucial for proper cutting and to avoid damage to the bush hog.

Post-Installation:

• Test Run: Once everything is secure, conduct a short test run to ensure the blades are rotating correctly and there are no vibrations or unusual noises. Always do this in a clear, open area away from obstacles and people.
• Regular Maintenance: Regularly inspect your bush hog blades for wear and tear. Replace worn or damaged blades promptly to ensure optimal performance and safety.
