Your safety and the safety of others are paramount. Always observe the following safety precautions when handling, installing, or operating with mower blades.

• Chotsani Mphamvu: Before performing any work on the mower deck, ensure the engine is off, the spark plug wire is disconnected (for gasoline engines), or the battery is removed (for electric mowers) to prevent accidental starting.
• Valani Zida Zoteteza: Always wear heavy-duty gloves to protect your hands from sharp blade edges. Safety glasses are also recommended to protect your eyes from debris.
• Mphepete Zakuthwa: Mower blades are extremely sharp. Handle them with extreme care to avoid cuts.
• Secure Mower: Ensure the mower is on a stable, level surface and cannot roll or tip over during blade replacement. Use jack stands if lifting the mower.
• Onani Blades: Before each use, inspect blades for damage, cracks, or excessive wear. Replace damaged blades immediately.

3.2 Blade Replacement Procedure

1. Konzani Chometa Ndodo:
   • Ensure the mower engine is off and cooled down.
   • Disconnect the spark plug wire or remove the battery to prevent accidental starting.
   • Position the mower on a flat, stable surface. If necessary, lift the front or side of the mower using a jack and secure it with jack stands.

   • Wear heavy-duty gloves and safety glasses.
   • Place a wood block between the blade and the mower deck to prevent the blade from turning while loosening the bolt.
   • Using the appropriate wrench or socket, loosen and remove the blade bolt. Note the orientation of any washers or spacers.
   • Chotsani mosamala tsamba lakale.
3. Clean Deck (Optional):
   • While the blades are off, it is a good opportunity to clean any accumulated grass clippings and debris from the underside of the mower deck using a wire brush or scraper.
4. Ikani Masamba Atsopano:
   • Ensure the new Oregon 92-123 blade is oriented correctly. The cutting edge should face outwards and upwards towards the deck. The curved "lift" portion of the blade should point towards the deck to create airflow.
   • Align the blade's center hole with the spindle and ensure any alignment pins or holes on the blade match those on the spindle.
   • Reinstall any washers or spacers in their original orientation.
   • Thread the blade bolt by hand to ensure it is not cross-threaded.
   • Place the wood block again to prevent the blade from turning.
   • Tighten the blade bolt using a torque wrench to the manufacturer's specified torque. For Kubota mowers, this is typically between 70-90 ft-lbs (95-122 Nm). Refer to your mower's specific manual for exact torque specifications.
5. Tsimikizirani Kuyika:
   • After installation, manually spin each blade to ensure it rotates freely and does not wobble.
   • Reconnect the spark plug wire or reinstall the battery.

Once new blades are installed, proper operation ensures optimal cutting performance and blade longevity.

• Kuyang'anatu Ntchito: Before each mowing session, visually inspect the blades for any signs of damage, looseness, or excessive wear.
• Chotsani Zinyalala: Always clear the mowing area of any rocks, sticks, wires, or other foreign objects that could damage the blades or be thrown by them.
• Mowing Height: Adjust your mower's cutting height according to grass conditions. Avoid cutting more than one-third of the grass blade length at a time for healthier turf.
• Even Cut: If you notice an uneven cut, stop the mower and check the blades for proper installation, damage, or if they are dull.
• Kugwedezeka: Excessive vibration during operation can indicate a bent, unbalanced, or improperly installed blade. Immediately shut off the mower and investigate the cause.

5. Kusamalira

Regular maintenance extends the life of your blades and ensures consistent cutting performance.

• Kuyeretsa: After each use, clean grass clippings and debris from the blades and the underside of the deck. This prevents rust and maintains blade balance.
• Kunola: Blades should be sharpened regularly to maintain a clean cut. Use a blade sharpener or file, maintaining the original blade angle. Ensure the blade remains balanced after sharpening. An unbalanced blade can cause excessive vibration and damage to the mower. If you are unsure, consult a professional.
• Kuyendera: Periodically inspect blades for cracks, bends, or excessive wear. Replace blades that show significant damage or wear, as they can be dangerous and reduce cutting efficiency.
• Posungira: If storing the mower for an extended period, clean and lightly oil the blades to prevent rust.
