1. Introduction
This manual provides essential information for the safe and effective use, installation, and maintenance of your Woods RM59 RM500 Rear Mount Finish Mower Blade Kit. This kit includes three standard-duty, counter-clockwise (CCW) rotation blades, designed as original equipment manufacturer (OEM) replacements for Woods RM59 and RM500 rear mount mowers. Please read this manual thoroughly before installation and operation to ensure proper function and safety.
2. Important Safety Information
Always prioritize safety when working with mower blades. Failure to follow these safety instructions can result in serious injury or property damage.
- Disconnect Power: Always ensure the mower engine is off, the spark plug wire is disconnected, and the key is removed before performing any maintenance or installation.
- Wear Protective Gear: Use heavy-duty gloves, safety glasses, and appropriate footwear when handling blades. Blades are sharp and can cause severe cuts.
- Secure the Mower: Ensure the mower is on a stable, level surface and properly supported to prevent accidental movement during blade replacement.
- Inspect Blades: Before each use, inspect blades for damage, cracks, or excessive wear. Replace damaged blades immediately.
- Correct Rotation: Ensure replacement blades match the original blade's rotation (Counter-Clockwise for this kit). Incorrect rotation can lead to poor cutting performance and potential hazards.
- Tighten Fasteners: Always tighten blade mounting bolts to the manufacturer's specified torque settings. Loose bolts can cause blades to detach.

5. Installation Instructions

- Prepare the Mower:
- Park the mower on a firm, level surface.
- Turn off the engine, remove the ignition key, and disconnect the spark plug wire to prevent accidental starting.
- Engage the parking brake.
- If necessary, raise the mower deck to access the blades safely. Use appropriate lifting equipment and secure with jack stands.
- Remove Old Blades:
- Wearing heavy-duty gloves, use a block of wood or a specialized blade removal tool to hold the blade steady.
- Using a wrench, loosen and remove the blade mounting bolt(s) and any washers or spacers. Note the order of removal.
- Carefully remove the old blade.
- Inspect Components:
- Inspect the blade spindle, mounting hardware, and deck for any damage, wear, or debris. Clean as necessary.
- Replace any worn or damaged hardware.
- Install New Blades:
- Position the new Woods blade onto the spindle, ensuring the cutting edge faces the correct direction (downwards, towards the ground). The blade's curved or angled side should point up towards the deck.
- Confirm the blade's center hole aligns with the spindle and any alignment pins or features.
- Reinstall the mounting bolt(s) and washers in the correct order.
- Hand-tighten the bolt(s) initially.
- Torque Blades:
- Using a torque wrench, tighten the blade mounting bolt(s) to the torque specification provided in your mower's owner's manual. This is critical for safety and proper operation.
- Repeat for all three blades.

6. Operation Guidelines
Once the new blades are installed, operate your mower according to its original owner's manual. The new blades are designed to provide optimal cutting performance for your Woods RM59 or RM500 mower. Always ensure the cutting deck is clear of debris before starting the mower.
7. Maintenance
Regular maintenance of your mower blades ensures longevity and consistent cutting quality.
- Clean Blades: After each use, clean grass clippings and debris from the blades and underside of the mower deck. This prevents rust and maintains balance.
- Inspect for Damage: Regularly check blades for nicks, bends, cracks, or excessive wear. Replace blades that are severely damaged or worn.
- Sharpening: Blades should be sharpened periodically to maintain a clean cut. Use a blade sharpener or file, maintaining the original blade angle. Ensure blades are balanced after sharpening to prevent vibration. If you are unsure, consult a professional.
- Storage: If storing the mower for an extended period, clean and lightly oil the blades to prevent rust.
