Quick verdict: Match the Greenworks part number to the mower’s product number. Greenworks currently lists 29373 for mower 25223, while its 33301487A page lists 2500502 and 2501302. A “19-inch Greenworks blade” title alone does not settle the choice.

Find your mower in the manufacturer’s listings
| Your mower product number | Greenworks replacement listing | Buying check |
|---|---|---|
| 25223 | 29373 | Match the label and parts diagram before ordering. |
| 2500502 or 2501302 | 33301487A | Do not assume the 29373 listing covers these models. |
| 2539502VT / MO48L4214 | 33301487A | Match the full number, including its suffix. |
| Another Greenworks model | Check its own parts list | A common brand, voltage or deck size is insufficient. |
Why the Amazon title needs a second check
The linked Amazon listing identifies part 29373 but its title and compatibility text also mention other mower numbers. That conflicts with the narrower model list on Greenworks’ current 29373 page. Use the manufacturer’s model-specific information as the starting point and ask Greenworks to resolve any discrepancy for your exact mower.
For mower 25223, the Amazon listing is an option to compare once the selected item, part number and seller are confirmed. For 2500502 or 2501302, use the manufacturer’s 33301487A page above rather than assuming this Amazon variation is the correct blade.

Does a 19-inch mower need a blade exactly 19 inches long?
Not necessarily. Greenworks explains that blade length can be approximately an inch shorter than the deck designation to provide clearance. Its 33301487A specifications list an 18-inch blade for a 19-inch deck. Match the approved part rather than buying by a tape-measure reading alone.
Is it worth replacing the blade?
A correctly matched replacement makes sense when the existing blade is damaged or worn beyond the manual’s service limits. Uneven cutting can have other causes, including deck buildup or cutting-height settings. Inspect those before assuming a new blade will fix the result.
We have not compared these blades in mowing tests and cannot promise a runtime or cut-quality improvement. The useful distinction here is documented fit. See the electric mower replacement-parts guide for other brands and the maintenance and storage checklist for inspection and cleaning.
