Introduction
This manual provides essential information for the safe and effective use, installation, and maintenance of your Oregon 94-026 Replacement Lawn Mower Blade. Please read this manual thoroughly before attempting any installation or maintenance procedures. Proper handling and care will ensure optimal performance and longevity of the blade.
Important Safety Information
Always prioritize safety when working with lawn mower blades. Failure to follow these safety guidelines can result in serious injury.
- Always disconnect the spark plug wire or remove the battery from electric mowers before performing any maintenance or blade replacement.
- Wear heavy-duty gloves to protect your hands from sharp edges.
- Wear safety glasses to protect your eyes from debris.
- Ensure the mower is stable and cannot roll or tip over during blade replacement.
- Never attempt to sharpen or balance a damaged blade. Replace it immediately.
- Keep children and pets away from the work area.
Setup and Installation
Replacing your lawn mower blade is a critical maintenance task. Follow these steps carefully.
Tools Required:
- Heavy-duty work gloves
- Safety glasses
- Wrench or socket set (size may vary by mower model)
- Wood block or blade removal tool
- Wire brush (for cleaning)
Blade Replacement Procedure:
- Prepare the Mower: Disconnect the spark plug wire (gas mowers) or remove the battery (electric mowers) to prevent accidental starting. Position the mower on a flat, stable surface. If possible, tilt the mower so the carburetor side is up to prevent fuel leakage.
- Secure the Blade: Place a wood block between the blade and the mower deck to prevent the blade from turning while you loosen the bolt.
- Remove the Old Blade: Using the appropriate wrench or socket, loosen the blade bolt by turning it counter-clockwise. Once loose, remove the bolt, washer, and the old blade. Note the orientation of the old blade for correct installation of the new one.
- Inspect and Clean: Inspect the blade mounting area for any damage or wear. Clean any accumulated grass clippings or debris from the underside of the mower deck and around the blade spindle using a wire brush.
- Install the New Blade: Position the new Oregon 94-026 blade onto the spindle, ensuring the cutting edge faces the correct direction (typically towards the direction of rotation, with the curved 'wing' pointing upwards towards the deck). The center hole of the blade should align perfectly with the spindle.
- Secure the New Blade: Place the washer and blade bolt back onto the spindle. Hand-tighten the bolt, then use your wrench or socket to tighten it securely. Use the wood block again to prevent the blade from turning. Refer to your mower's owner's manual for specific torque specifications, if available.
- Final Check: Ensure the blade is firmly attached and spins freely without wobbling. Reconnect the spark plug wire or reinsert the battery.

Operating Guidelines
Once the new blade is installed, observe these general operating guidelines for optimal cutting performance and safety:
- Always ensure the mower deck is set to an appropriate cutting height for your lawn type.
- Avoid mowing wet grass, as it can clog the deck and lead to an uneven cut.
- Clear the mowing area of any debris (rocks, sticks, toys) that could damage the blade or be ejected.
- Mow at a consistent speed to achieve an even cut.
- Overlap your mowing passes slightly to avoid leaving uncut strips.
Maintenance
Regular maintenance of your blade ensures a clean cut and extends its lifespan.
- Cleaning: After each use, clean grass clippings and debris from the blade and the underside of the mower deck. This prevents rust and maintains balance.
- Inspection: Regularly inspect the blade for nicks, bends, or cracks. A damaged blade can cause excessive vibration and an uneven cut. Replace severely damaged blades immediately.
- Sharpening: Sharpen the blade periodically to maintain a keen cutting edge. A dull blade tears grass, leading to an unhealthy lawn. Use a blade sharpener or file, maintaining the original blade angle. Ensure the blade remains balanced after sharpening. If you are unsure, consult a professional.
- Balancing: An unbalanced blade can cause excessive vibration, leading to premature wear on mower components. After sharpening, check the blade's balance using a blade balancer. If unbalanced, remove a small amount of metal from the heavier side until balanced.
Troubleshooting
Refer to the table below for common issues and their potential solutions related to your mower blade.
| Problem | Possible Cause | Solution |
|---|---|---|
| Uneven cut / Ragged grass tips | Dull blade, bent blade, incorrect blade installation | Sharpen or replace blade, check blade for bends, ensure correct installation. |
| Excessive mower vibration | Unbalanced blade, bent blade, loose blade bolt | Balance or replace blade, check blade for bends, tighten blade bolt securely. |
| Poor grass discharge / Clogging | Dull blade, wet grass, excessive grass height | Sharpen blade, avoid mowing wet grass, mow more frequently or raise cutting height. |
