Husqvarna Mower Blade Cross Reference by Number
2026-10-22 · 8 min read
Husqvarna mower blades are listed under AYP-family 532- part numbers, so the same blade often fits Craftsman, Poulan and other AYP-built decks. To replace one, match the stamped number on the old blade with your deck width and centre hole — that pairing decides whether the replacement seats and cuts correctly.
How Husqvarna numbers its mower blades
Husqvarna blades follow the AYP (American Yard Products) house-code style: a 532- prefix followed by a six-digit number such as 532187256 or 532180054. The 532- prefix marks an AYP-family tooling run rather than a steel grade or hardness, so two blades sharing a prefix can still differ in length and hole type. Recognising the format keeps you from quoting a zero-turn blade when a rider size is what the deck needs. Our guide to matching a blade by OEM number shows how to read the format before you order.
Which Husqvarna blade numbers cross to other brands
Many Husqvarna numbers cross to Craftsman, Poulan, Poulan Pro, Weed Eater and AYP because those brands share the same AYP-family decks. A 532187256 fitted to a Husqvarna zero-turn will often also fit a Craftsman or Poulan deck of the same width and hole type. The overlap is a tooling fact, not a coincidence, so a single drawing serves several brand labels. We are an independent manufacturer and not an authorised Husqvarna dealer; brand names appear here only for fitment reference.
| Brand family | Number style | Typical deck | Example |
|---|---|---|---|
| Husqvarna / AYP | 532-XXXXXX | 42–54 in rider / zero-turn | 532187256 |
| Craftsman (AYP) | 532-XXXXXX | 42–54 in rider | 532127843 |
| Poulan / Poulan Pro (AYP) | 532-XXXXXX / 138XXX | 42 in rider | 532138971 |
| Husqvarna / Craftsman | 405380 / 134149 | 42–46 in rider | 405380 |
These share tooling, so confirm deck width and centre hole before treating any cross as exact.
Common Husqvarna blade numbers and what they fit
The numbers below are real public Husqvarna and AYP part-number styles, shown so you can recognise the format stamped on your own blade. They are fitment reference only — we are an independent manufacturer and not an authorised Husqvarna dealer.
- 532187256 — a 54-inch high-lift blade for the Husqvarna Z254F zero-turn deck.
- 532180054 — a 48-inch bagging blade for the Husqvarna Z248F zero-turn deck.
- 532173921 — a 48-inch mulching blade for Husqvarna YTH24V48 riding tractors.
- 405380 — a 46-inch blade for Husqvarna YTH22V46 riding tractors.
- 138971 / 532138971 — a 42-inch blade shared across Husqvarna, Craftsman and Poulan decks.
- 134149 / 532134149 — a 42-inch mulching blade used on many AYP-family riders.
If your number is not in this short list, that is normal — Husqvarna has issued many blade numbers across its model years. Send the exact stamping and your deck width and we will cross-reference it against the model index.
Zero-turn Husqvarna blade numbers
Husqvarna zero-turn decks (the Z200, Z400 and Z500 series) use 532- numbers that are specific to deck width, so a Z248F 48-inch blade will not fit a Z254F 54-inch deck. The table below maps the common zero-turn blade numbers to the decks that carry them.
| Mower | Deck | Blade number | Lift type |
|---|---|---|---|
| Z248F | 48 in | 532180054 | Bagger |
| Z254F | 54 in | 532187256 | High-lift |
| YTH24V48 (rider) | 48 in | 532173921 | Mulching |
| YTH22V46 (rider) | 46 in | 405380 | Bagging / high-lift |
Deck width causes the most zero-turn fitment failures, so confirm the number printed on the deck plate before ordering.
Where to find the Husqvarna blade number
The blade number is stamped on the flat near the centre hole, but grass and rust usually hide it, so wire-brush the area first. If the old blade is gone, the deck or model plate under the seat or near the discharge chute gives the machine model, which is enough to look the number up. The owner's manual and Husqvarna parts diagrams both list the blade number by model. Read the stamping on the model index to see which profiles we keep for Husqvarna-fit decks.
What a correct Husqvarna-fit blade must match
A replacement is correct only when every mounting and cutting dimension lines up, because a close-enough blade vibrates, cuts unevenly or fails to seat. The table below is the checklist we use before quoting any Husqvarna-fit blade.
| Spec | Why it matters | How to confirm |
|---|---|---|
| Overall length | Seats the spindle and clears the deck | Measure tip to tip |
| Centre hole | Mounts on the mandrel | Match hole type exactly |
| Thickness | Load rating under impact | Caliper the old blade |
| Lift type | Decides cut result | Compare blade profile |
Length and hole type cause the most fitment failures, so double-check those two before anything else.
Are all 532187256 blades the same?
No — 532187256-style blades are not identical just because they share the number, because deck width and hole detail decide the actual length and fit. A blade cut for a 54-inch Z254F deck will not suit a 48-inch Z248F deck even when the number matches. Always confirm the deck size printed on the machine plate against the blade you intend to fit, then check the centre-hole type.
How Husqvarna-fit blades are made to spec
Husqvarna-fit blades we supply are made to match the original specifications of the OEM number you send, cut from 40Mn manganese steel and hardened to a 45–50 HRC band so the edge holds through grit yet will not crack on hidden stone. 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. We are an independent manufacturer; brand names are used for fitment reference only.
Can you order custom Husqvarna-fit blades?
Yes — custom Husqvarna-fit blades are made to a supplied sample or drawing, typically from 40Mn steel and held in the 45–50 HRC band we run across the catalogue. Share the old blade or its part number and we will confirm fitment, profile and run size. The minimum order for a custom profile is normally 300 pieces, which 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 browse the model index for stock shapes.
Frequently Asked Questions
Are Husqvarna and Craftsman blade numbers the same?
Yes — many Husqvarna numbers are identical to Craftsman numbers because both brands use AYP-family 532- tooling, so blades cross to Poulan, AYP and Weed Eater as well. A number match still requires the same deck width and centre hole, so confirm those two before ordering.
Where is the blade number on a Husqvarna mower?
The blade number is stamped near the centre hole on the flat of the blade, and on the deck or model plate under the seat or near the discharge chute. Wire-brush the area around the centre hole first, because grass and rust usually hide the stamping. If the plate is unreadable, the machine model and deck width are enough to look the number up.
Can I fit a non-Husqvarna blade on my Husqvarna mower?
Yes — you can fit an independent blade as long as the length, centre hole, thickness and lift match the original, because the mower cares about the geometry, not the brand on the box. We make Husqvarna-fit blades made to match the original specifications and are an independent manufacturer, not an authorised dealer. Match the dimensions and the blade will seat and cut correctly.
How do I match a Husqvarna blade if the stamping is worn?
Wire-brush the flat near the centre hole, then read the deck or model plate under the seat or near the discharge chute if the blade is unreadable. With the machine model and deck width you can look the blade number up in Husqvarna parts diagrams. Send us those details and we will cross-reference them against our model index.
What is the minimum order for custom Husqvarna-fit blades?
The minimum order for a custom Husqvarna-fit blade is typically 300 pieces per profile, which covers the setup and heat-treat run for a made-to-sample blade. Share the part number or a drawing and we will confirm fitment and quote the run before any cutting begins. Send your specifications to get a quote sized to your machine.
