4. การเตรียมและการติดตั้ง (การเปลี่ยนใบพัด)

Replacing mower blades requires careful attention to safety and proper procedure. Refer to your mower's owner's manual for specific instructions related to your model.

เครื่องมือที่จำเป็น:

• ถุงมือสำหรับงานหนัก
• แว่นตานิรภัย
• Wrench or socket set (appropriate size for blade bolts)
• ประแจแรงบิด
• Block of wood or blade removal tool

ขั้นตอนการติดตั้ง:

1. เตรียมเครื่องตัดหญ้า: Park the mower on a level surface. Turn off the engine and remove the ignition key. Disconnect the spark plug wire (for gas models) or remove the battery pack (for electric models) to prevent accidental starting.
2. Access the Blades: Refer to your mower's manual for the safest way to tilt or lift the mower deck to access the blades. Ensure the mower is securely supported.
3. ถอดใบมีดเก่าออก: Place a block of wood between the blade and the mower deck to prevent the blade from turning. Using the appropriate wrench, loosen and remove the blade bolt. Carefully remove the old blade. Note the orientation of the blade for correct installation of the new one.
4. ตรวจสอบส่วนประกอบ: Inspect the blade spindle and mounting area for any damage or debris. Clean as necessary.
5. ติดตั้งใบมีดใหม่: Position the new Yard Force high-lift blade onto the spindle, ensuring the cutting edge is facing the correct direction (typically towards the deck when viewed from below). The high-lift wing should point upwards towards the deck.
6. Tighten Blade Bolts: Reinstall the blade bolt and washer. Use the block of wood to secure the blade. Tighten the blade bolt to the torque specification provided in your mower's owner's manual. Proper torque is critical for safety and performance.
7. ทำซ้ำขั้นตอนเดียวกันสำหรับใบมีดที่สอง: Follow the same steps for the second blade.
8. การตรวจสอบขั้นสุดท้าย: Once both blades are installed, ensure they are securely fastened and rotate freely without obstruction. Reconnect the spark plug wire or reinstall the battery pack.

5. Operating (Blade Functionality)

The high-lift design of these Yard Force blades is engineered to create a strong upward airflow under the mower deck. This airflow stands the grass blades upright just before they are cut, resulting in a cleaner, more uniform cut. The increased air velocity also efficiently discharges grass clippings, making these blades particularly effective for bagging applications.

For optimal cutting performance, ensure your mower deck is properly leveled and the cutting height is adjusted according to grass conditions. Avoid mowing wet grass, as it can clump and reduce the effectiveness of the high-lift design.

6. การบำรุงรักษา

Regular maintenance of your mower blades ensures continued performance and safety.

• การทำความสะอาด: After each use, clean grass clippings and debris from the blades and underside of the mower deck. Built-up grass can reduce airflow and cutting efficiency.
• การตรวจสอบ: Periodically inspect blades for sharpness, bends, cracks, or excessive wear. Replace blades that show signs of damage.
• การลับคม: 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 to prevent mower vibration. If you are unsure, have blades professionally sharpened or replaced.
• การสร้างสมดุล: An unbalanced blade can cause excessive vibration, leading to premature wear on mower components and an uneven cut. After sharpening, check the blade balance using a blade balancer.

7 การแก้ไขปัญหา

If you experience issues related to your mower's cutting performance, consider the following:

• การตัดที่ไม่สม่ำเสมอ:
  • Check if blades are dull or damaged.
  • Ensure blades are installed correctly and tightened to proper torque.
  • Verify mower deck is level.
• การสั่นสะเทือนมากเกินไป:
  • Inspect blades for bends or damage.
  • Check if blades are properly balanced.
  • Ensure blade bolts are tightened to specification.
• Poor Bagging Performance:
  • Clean underside of mower deck and discharge chute to remove clogs.
  • Ensure blades are sharp.
  • ควรหลีกเลี่ยงการตัดหญ้าที่เปียกหรือสูงเกินไป
