Safety Information
Always prioritize safety when working with lawn mower blades. Failure to follow these safety guidelines can result in serious injury.
- Disconnect Spark Plug: Before performing any work on the mower deck, always disconnect the spark plug wire to prevent accidental engine starting.
- Wear Protective Gear: Always wear heavy-duty gloves and eye protection when handling blades. Blades are sharp and can cause cuts.
- Secure the Mower: Ensure the mower is on a flat, stable surface and properly supported before lifting or tilting the deck.
- Inspect Blades Regularly: Check blades for damage, bends, or excessive wear before each use.
- Use Correct Tools: Utilize appropriate tools for installation and removal to prevent damage to fasteners or components.
Installation Instructions
Follow these steps to properly install the Oregon 92-116 Heavy Duty Blades on your 72-inch Kubota Pro Deck.
- Prepare the Mower: Ensure the mower engine is off and the spark plug wire is disconnected. Position the mower on a stable, level surface.
- Access the Deck: Safely lift or tilt the mower deck to expose the underside where the blades are mounted.
- Remove Old Blades: Using a wrench or socket, carefully remove the bolt securing the old blade to the spindle. You may need a blade removal tool or a block of wood to prevent the blade from turning. Note the orientation of the old blade for correct installation of the new one.
- Clean Spindle Area: Clean any grass clippings or debris from the spindle and blade mounting area.
- Install New Blade: Place the new Oregon 92-116 blade onto the spindle, ensuring the cutting edge faces the correct direction (typically towards the direction of rotation for cutting). The center hole of the blade should align perfectly with the spindle shaft.
- Secure Blade: Reinstall the blade bolt and washer. Tighten the bolt securely to the manufacturer's recommended torque specifications. Over-tightening or under-tightening can cause issues.
- Repeat for All Blades: Follow the same procedure for all remaining blades on the deck.
- Final Check: Once all blades are installed, ensure they are securely fastened and can rotate freely without obstruction. Reconnect the spark plug wire.

Operating Guidelines
While these blades are designed for heavy-duty use, proper operating practices are essential for optimal performance and longevity.
- Clear Debris: Before mowing, clear the area of any rocks, sticks, or other foreign objects that could damage the blades or be ejected.
- Mow at Appropriate Height: Adjust your mower deck to the appropriate cutting height for the grass type and conditions.
- Avoid Wet Grass: Mowing wet grass can lead to clumping, uneven cuts, and increased strain on the blades and mower.
- Regular Inspection: Periodically check the blades for excessive wear or damage during extended mowing sessions.
Maintenance
Regular maintenance ensures the blades perform efficiently and safely.
- Blade Inspection: After each use, inspect blades for nicks, bends, or cracks. Damaged blades should be replaced immediately.
- Cleaning: Remove grass clippings and debris from the blades and underside of the deck after each use. This prevents rust and maintains balance.
- Sharpening: Blades should be sharpened regularly to maintain cutting efficiency. Use a blade sharpener or file, ensuring the original blade angle is maintained. Sharpen both ends equally to maintain blade balance. Unbalanced blades can cause excessive vibration and damage to the mower.
- Replacement: Replace blades when they become excessively worn, bent, or damaged beyond repair. The frequency of replacement depends on usage and mowing conditions.
