Where is Serial Number On Greenworks Mower(5 Locations)

The serial number is a unique identifier that distinguishes your mower from others of the same model, and it’s often required when contacting customer service or verifying compatibility for accessories.

In this guide, we’ll explore the typical locations for the serial number on various Greenworks mowers, why it’s important, and some tips for finding it quickly and easily.

Where is Serial Number On Greenworks Mower

1. Rear Flap or Bag Door Area

For most Greenworks walk-behind mowers, such as the 40V, 60V, or 80V cordless models, the serial number is located on a label on the rear flap or bag door area.

This is the part of the mower where grass clippings are discharged or collected in the bag. The label is usually a small, rectangular sticker that includes the model number, serial number (often labeled “S/N”), and sometimes a date code.

  • How to Check: Open or lift the rear flap (if your mower has a grass catcher bag, it’s near this attachment point). Look for a white or silver sticker with printed numbers and letters. The serial number typically follows “S/N” and includes a combination of letters and digits.

2. Deck of the Mower

On some Greenworks mowers, particularly those sold at retailers like Costco, the serial number may be found on a sticker located on the mower deck. This is the main body of the mower, often near the top or side where the cutting blade is housed.

  • How to Check: Inspect the top or sides of the deck for a sticker. Be cautious, as there may be multiple labels on the deck (e.g., one for the engine or blade), so ensure you’re looking at the one for the overall unit. The serial number will be clearly marked with “S/N” or “Serial Number.”

3. Near the Handle or Shaft

For certain Greenworks models, especially those with adjustable handles, the serial number might be located near the handle or on the shaft connecting the handle to the mower body. This is more common for string trimmers or hedge trimmers but can apply to some mowers as well.

  • How to Check: Examine the handle area, particularly where it attaches to the mower or folds for storage. Look for a sticker on the handlebar or the shaft just below it.

4. Robotic Mowers (e.g., Greenworks Optimow)

For robotic mowers like the Greenworks Optimow S, the serial number is often found on the underside of the unit or near the charging station connection. A YouTube guide from Greenworks specifically notes that the serial number for the Optimow S is critical for registration and can be found on a label on the mower’s body.

  • How to Check: Carefully flip the robotic mower over (ensure it’s powered off and blades are disengaged for safety). Look for a label on the underside or near the charging port. Alternatively, check the user manual or packaging for a duplicate sticker.

5. Under the Seat (Riding Mowers)

For Greenworks riding mowers, such as the Pro RZ42M60, the serial number is typically located under the seat or on the frame near the control levers.

  • How to Check: Lift the seat or check the frame area near the controls. The sticker should be easily visible and include both the model and serial numbers.

Tips for Finding the Serial Number

If you’re struggling to locate the serial number, here are some practical tips:

  • Check the Manual or Packaging: The serial number is sometimes printed on the owner’s manual or the original box. Greenworks manuals, like the one for the Pro RZ42M60, often include a section for recording the serial number.
  • Look for the “S/N” Label: The serial number is almost always preceded by “S/N” or “Serial Number” on the sticker to distinguish it from the model number or other codes.
  • Clean the Area: Dirt or grass clippings can obscure the label. Wipe down the suspected areas with a cloth to make the sticker more visible.
  • Avoid Confusion with Other Numbers: Mowers may have multiple stickers for components like the deck or battery. Ensure you’re looking at the sticker for the entire unit, not just a part.

Final Thoughts

Finding the serial number on your Greenworks mower is straightforward once you know where to look. For most walk-behind models, check the rear flap or bag door area; for riding mowers, look under the seat; and for robotic mowers, inspect the underside.

Always double-check that you’re noting the serial number (marked “S/N”) and not the model number or another code. If you’re still having trouble, Greenworks’ customer service is a reliable resource.
