Scag Mower Blade OEM Numbers: Cross-Reference Guide

Scag mower blades carry OEM part numbers in the 481xxx and 482xxx families, stamped near the centre hole. A correct replacement matches the number to your deck width, centre-hole type, thickness and lift style — not the number alone — so the blade seats on the spindle and cuts cleanly.

How does Scag number its mower blades?

Scag numbers its blades in two families — 481xxx for standard and hi-lift walk-behind decks, and 482xxx for the larger zero-turn decks — so the prefix tells you the deck class before you read the rest. The suffix then points to the blade profile within that class.

Walk-behind Scag decks use a tight, well-documented set of numbers. A 36-inch or 52-inch deck often shares the same standard blade number, while the 48-inch and 61-inch decks each get their own. Hi-lift and mulching versions carry neighbouring numbers in the same block, which is why reading only the first digits is not enough.

Part number	Blade type	Deck size	Approx. length
481707	Standard	36" / 52"	21"
481706	Standard	48"	21"
481708	Standard	61"	21"
481711	Hi-lift	36" / 52"	21"
481710	Hi-lift	48"	21"
481712	Hi-lift	61"	21"
483317	Eliminator mulching	36" / 52"	21"
483316	Eliminator mulching	48"	21"
483318	Eliminator mulching	61"	21"

The 4828xx series covers the bigger zero-turn decks such as the Cheetah, Turf Tiger and Tiger Cat, and the lengths run longer than the walk-behind set.

Part number	Common use	Cross-referenced brands
482877	48" mulching deck	Bad Boy, Hustler, Snapper
482878	52" bagging deck	Ferris, Toro, Wright
482879	21" notched blade	Ariens, Bad Boy, Gravely
482882	72" velocity deck	used across Scag rider line

These numbers are public part-number styles for fitment reference only. We are an independent manufacturer and not an authorised Scag dealer, so none of them are our own catalogue numbers.

Where do I find the blade number on a Scag 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 on the mower, 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.

What do the Scag blade numbers actually tell you?

The digits are a house code for the blade family and deck class, not a full specification, so the same number across sources can describe different lengths or hole patterns. Treat the number as a lookup key, then confirm the physical dimensions.

A 481707 from one listing and a 481707 from another should be identical, but a 4817xx number does not automatically mean it fits your deck. Length, centre-hole type, thickness and lift all vary by deck width, and the parts manual is the only place those details are fixed. Pair the number with the deck size every time.

Are Scag blades interchangeable across deck sizes?

Scag 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, 481707 covers the 36-inch and 52-inch standard decks, while 481706 is the 48-inch standard blade. Both are 21-inch long, yet they are not the same part because the mounting and lift geometry differ. Check the four dimensions before assuming a swap.

How do I match a Scag number to a replacement?

Match a Scag 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 Scag-fit replacement use?

A Scag-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 Scag-fit blades made to a sample?

You can order custom Scag-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 Scag blade numbers the same across every deck?

No — Scag blade numbers repeat across deck sizes only within a family, and a 36-inch deck number such as 481707 is not the same part as the 48-inch 481706. 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 4817xx number mean on a Scag blade?

A 4817xx number marks Scag's standard and hi-lift walk-behind blade family, used across 36-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-Scag blade on my Scag 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 Scag-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 Scag 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 Scag-fit blades?

The minimum order for a custom Scag-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.
