Ferris Mower Blades: Deck Size & Fitment Guide
2026-10-31 · 8 min read
Ferris mower blades are chosen by deck width, centre-hole type, length and lift — not by the model name alone — because the suspension decks run several widths on the same spindle pattern. A correct replacement seats on the spindle and cuts cleanly without buzzing or scalping.
What blade numbers do Ferris mowers use?
Ferris blades are identified by a stamped part number near the centre hole, and that number points to a deck width and blade profile rather than a single machine. Ferris sits in the same Briggs & Stratton family as Snapper and Simplicity, which is why one blade number often cross-references across those brands.
Because the number is a house code, the same digits can describe different lengths or hole patterns depending on the deck. Treat the number as the start of a lookup, then confirm the physical dimensions against the old blade before ordering.
| Catalogue number | Deck width | Length | Centre hole | Lift type |
|---|---|---|---|---|
| 482878 | 36"–52" | 18" (457 mm) | Round | Notched high lift |
| 5101755 | 61" | 21" | Round | High lift |
These two catalogue blades list Ferris among their fitment brands, so they are the reference points for the deck widths Ferris suspension mowers most often run. We are an independent manufacturer and not an authorised Ferris dealer, so none of them are our own house numbers.
How do I match a Ferris blade to my deck?
Match a Ferris blade by recording four facts — overall length, centre-hole type, thickness and lift — then compare them against the original before ordering, because the deck width alone does not fix the geometry. 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.
Which blade type suits a Ferris suspension deck?
A notched or standard high-lift blade suits most Ferris suspension decks, because the independent suspension keeps the deck level and a high-lift profile lifts clippings into the chute under faster ground speeds. Mulching blades trade that lift for fine recutting, so pick by what you do with the clippings.
| Blade type | Suited to | Trade-off on a Ferris deck |
|---|---|---|
| Standard 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 |
| Mulching | Recycling leaves and fine clippings | Needs slower ground speed |
The 482878 (notched high lift) and 5101755 (high lift) above are the two Ferris-fit profiles we stock, covering 36–52-inch and 61-inch decks respectively. A 42-inch high-lift blade such as 942-04308-high-lift fills the smaller commercial width if your deck is under 48 inches.
Are Ferris blades interchangeable across deck sizes?
Ferris 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 52-inch deck will not suit a 48-inch deck even when the family prefix matches.
For example, 482878 covers the 36-inch through 52-inch notched high-lift range, while 5101755 is the 61-inch high-lift blade. Both are round-hole blades, yet they are not the same part because the length and lift geometry differ. Check the four dimensions before assuming a swap, and use the OEM matching guide to turn a worn stamping into a confirmed fit.
What steel and hardness should a Ferris-fit blade use?
A Ferris-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 Ferris-fit blades made to a sample?
You can order custom Ferris-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 Ferris blade numbers the same across every deck?
No — Ferris blade numbers repeat across deck sizes only within a profile, and a 36-inch deck number is not the same part as a 61-inch one. 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 Ferris suspension deck change about blade choice?
A Ferris suspension deck stays level over bumps, so a high-lift blade keeps lifting clippings into the chute at faster ground speeds without scalping. The suspension does not change the spindle pattern, so you still match by deck width, centre hole, length and lift — it just rewards a blade that holds those dimensions tightly.
Can I fit an independent blade on my Ferris 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 Ferris-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 Ferris 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 Ferris-fit blades?
The minimum order for a custom Ferris-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 Ferris 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.
