Bad Boy Mower Blade Numbers: Fitment Guide
2026-10-28 · 8 min read
Bad Boy mower blades carry part numbers in the 038-xxxx-xx family, stamped near the centre hole. A correct replacement matches the number to deck width, centre-hole type and lift style — not the number alone — so the blade seats on the spindle and cuts cleanly.
What do Bad Boy blade numbers mean?
Bad Boy blade numbers run in the 038-xxxx-xx family, where the prefix marks the blade class and the suffix points to the deck and profile, so the digits are a house code rather than a full specification. The same family covers 42-inch through 61-inch decks, which is why the number alone never fixes the length or hole pattern.
Treat the number as a lookup key, then confirm the physical dimensions before ordering. A 038-0005-00 from one listing and the same number from another should be identical, but the family prefix does not by itself tell you the deck width or centre-hole type. Pair the number with the four measurements every time.
| Our part number | Fits Bad Boy deck | Blade type | Also cross-references |
|---|---|---|---|
| 038-0005-00 | 54" (Magnum MZ / Maverick) | High-lift | — (Bad Boy pattern) |
| 038-2007-00 | 60" (Maverick / ZT Elite) | High-lift | Gravely, Exmark, Toro, Hustler |
| 482877 | 48" | Mulching | Snapper, Scag, Hustler |
| 5101755 | 61" | High-lift | Scag, Ferris, Simplicity, Bobcat |
These four are part-number styles we manufacture that fit Bad Boy decks, listed for fitment reference only. We are an independent manufacturer and not an authorised Bad Boy dealer, so none of them are official Bad Boy catalogue numbers.
Where do I find the blade number on a Bad Boy mower?
The number is stamped on the flat of the blade near the centre hole, but grass and rust hide it, so wire-brush the area or read the deck plate if the blade is gone. With the machine model and deck width you can look the blade up in the manufacturer's parts catalogue.
If the blade is still mounted, turn off the engine, disconnect the spark plug, and tip the deck to read the stamping. When the blade is missing, the model plate near the discharge chute or under the seat carries the machine model — enough to find the correct number in the blade OEM matching guide.
Are Bad Boy blades interchangeable across deck sizes?
Bad Boy blades interchange only when length, centre hole, thickness and lift also match, which they rarely do across different deck widths, so always confirm the deck size printed on the machine plate. A number from a 54-inch deck will not suit a 60-inch deck even when the family prefix matches.
For example, 038-0005-00 is the 54-inch high-lift blade, while 038-2007-00 is the 60-inch high-lift blade — both carry the same 038- family prefix yet are different parts because the mounting and lift geometry differ. Check the four dimensions before assuming a swap.
How do I match a Bad Boy number to a replacement?
Match a Bad Boy number to a replacement by recording four facts — overall length, centre-hole type, thickness and lift — then compare them against the original before ordering. The number opens the search; the measurements close the fit.
Measure the old blade tip to tip, note whether the centre hole is round, star or a multi-point pattern, caliper the thickness, and say which way the blade turns. With those four facts plus the deck width, a supplier can name the right profile even when the stamping is illegible. Our blade measuring guide shows exactly what to record before you write to a supplier.
What blade steel and hardness should a Bad Boy-fit replacement use?
A Bad Boy-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 commercial 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. For the steel science behind the hardness band, see our blade steel and hardness article.
Can I order custom Bad Boy-fit blades made to a sample?
You can order custom Bad Boy-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 browse the model index for stock shapes.
Frequently Asked Questions
Are Bad Boy blade numbers the same across every deck?
No — Bad Boy blade numbers repeat across deck sizes only within a family, and a 54-inch number such as 038-0005-00 is not the same part as the 60-inch 038-2007-00. Always confirm the deck width printed on the machine plate against the blade you intend to fit, because the family prefix alone does not fix the length or hole pattern.
What does a 038-xxxx-xx number mean on a Bad Boy blade?
A 038-xxxx-xx number marks Bad Boy's blade family code, used across 42-inch through 61-inch decks rather than a single machine. The digits are a house code for the blade family and revision, not a full specification, so always pair the number with the deck width and the four physical dimensions.
Can I fit a non-Bad Boy blade on my Bad Boy 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 Bad Boy-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 find my Bad Boy blade number if the stamping is worn?
Wire-brush the flat near the centre hole, then read the deck or model plate near the discharge chute or under the seat if the blade is unreadable. With the machine model and deck width you can look the blade number up in the manufacturer's parts catalogue. Send us those details and we will cross-reference them against our model index.
What is the minimum order for custom Bad Boy-fit blades?
The minimum order for a custom Bad Boy-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.
Not sure which Bad Boy blade fits your deck, or want a custom profile made to a sample? Send us your part number or a photo of the old blade and we will confirm fitment and quote — or start from the model index.
