Poulan Pro Mower Blade Replacement by Number
2026-11-03 · 8 min read
Poulan Pro mower blades are matched by the stamped OEM number and confirmed with deck width and centre-hole type, because Poulan Pro is a badge brand built on the AYP/Husqvarna spindle pattern. A replacement made to match the original specifications seats and cuts without guessing at a "Poulan-only" part.
What blade numbers do Poulan Pro mowers use?
Poulan Pro blades carry the same AYP-style numbers used across the Husqvarna family, so the digits describe a deck width and profile rather than a single machine. Common 42-inch fitments such as 422719, 134149 and 405380 appear under Poulan, Husqvarna and Craftsman alike. The number opens the lookup; the physical blade closes the fit.
| Catalogue number | Deck width | Type | Also listed for |
|---|---|---|---|
| 422719 | 42" | Mulching | Husqvarna, Craftsman, Poulan |
| 405380 (notched high lift) | 42"–46" | Notched high lift | Husqvarna, Craftsman, Poulan |
| 173920 (mulching) | 48" | Mulching | Husqvarna, Craftsman, Poulan |
These three blades list Poulan among their fitment brands, so they are the reference points for the deck widths Poulan Pro machines most often run. We are an independent manufacturer and not an authorised Poulan dealer, so none are our own house numbers.
Are Poulan Pro blades a proprietary design?
Poulan Pro blades are not a proprietary design, because the brand is a badge label whose machines share the AYP/Husqvarna spindle and centre-hole pattern with several other names. That is why the same stamped number fits more than one brand on the deck. Matching by number plus measured dimensions reaches the right profile without chasing a part marked "Poulan Pro" alone.
This badge-brand reality matters when a deck is older or the stamping is worn. A Poulan Pro rider from one year may use the same 42-inch mulching blade as a Craftsman or Husqvarna tractor of the same width. Our OEM matching guide explains how to read a worn stamping into a confirmed fit.
How do I match a Poulan Pro blade by number?
Match a Poulan Pro blade by pairing the stamped number with four measured facts — overall length, centre-hole type, thickness and lift — because deck width alone does not fix the geometry. The number selects the candidate; the measurements confirm it.
Measure the old blade tip to tip, note whether the centre hole is round, star or multi-point, caliper the thickness, and say which way the blade turns. With those four facts plus deck width, a supplier can name the right profile even when the digits are illegible. Our blade measuring guide shows exactly what to record before you write to a supplier.
Which blade type suits a Poulan Pro deck?
A mulching or high-lift blade suits most Poulan Pro decks, because the lighter spindle loads and slower ground speeds of a big-box rider favour a profile that lifts clippings into the chute. Mulching blades trade some lift for fine recutting, so pick by what you do with the clippings.
| Blade type | Suited to | Trade-off on a Poulan Pro deck |
|---|---|---|
| Mulching | Recycling leaves and fine clippings | Needs slower ground speed |
| High lift | Bagging, tall or wet grass | Can throw clippings harder than needed |
| Notched high lift | Bagging plus durability on grit | Heavier; slightly more draw |
The 422719 (42-inch mulching) and 405380 notched high lift cover the common 42–46-inch Poulan Pro widths, while the 173920 mulching blade serves the 48-inch decks. Browse the model index for stock shapes across every width we cut.
What steel and hardness should a Poulan Pro-fit blade use?
A Poulan Pro-fit replacement should be cut from 40Mn manganese steel and hardened to a 45–50 HRC band, which holds the edge through grit yet resists cracking on hidden stone. That balance, not a single high number, is what keeps a deck blade working through a long season.
We run production in Guangde, Anhui, where the plant has made blades since 2008 and now employs more than 800 people with a daily capacity of 50,000 pieces. The same heat-treat control that decides working life is detailed on our quality page, which is the part of production that most affects how a blade performs under real mowing load.
Can I order custom Poulan Pro-fit blades made to a sample?
You can order custom Poulan Pro-fit blades made to a supplied sample or drawing, and the minimum run is normally 300 pieces per profile. Share the old blade or its part number and we will confirm fitment, profile and run size before any cutting begins.
Blades we supply are made to match the original specifications of the part number you send, cut from 40Mn steel and held in the 45–50 HRC band we run across the catalogue. The 300-piece minimum covers the setup and heat-treat run for a made-to-sample blade. Send your part number or a photo of the old blade to start, or see the model index for stock shapes.
Frequently Asked Questions
Are your Poulan Pro-fit blades original Poulan Pro parts?
We are an independent manufacturer and not an authorised Poulan dealer, so our blades are not original factory parts. They are made to match the original specifications of the part number you send, cut from 40Mn steel and held in the 45–50 HRC band we run across the catalogue.
How do I find the part number on a Poulan Pro blade?
Look for a stamped number near the centre hole on the top face of the old blade, because that is where AYP-family and contract manufacturers usually place the identifier. If the stamping is worn, measure length, centre hole, thickness and lift, then match those four facts to a Poulan-fit profile instead of relying on the digits alone.
Can I use a universal blade on a Poulan Pro deck?
A true universal blade rarely fits a Poulan Pro spindle correctly, because the centre hole, length and lift must match the AYP deck geometry exactly. Always match the four measured dimensions to a Poulan-fit profile instead of assuming a generic blade will seat and balance safely.
What is the minimum order for custom Poulan Pro-fit blades?
The minimum order is 300 pieces per blade profile, which covers the setup and heat-treat run for a made-to-sample blade. Custom steel such as SK5 can be quoted, and mixed profiles can be combined across a single production window to reach the minimum.
How often should I replace Poulan Pro mower blades?
Replace Poulan Pro blades when the cutting edge shows nicks deeper than a coin, when the ends are worn past the original width, or when you see cracks near the centre hole. Walk-behind and light rider decks typically need a fresh blade each season, with mid-season sharpening in between rather than waiting for failure.
