Toro Mower Blade OEM Numbers: Cross-Reference Guide
2026-10-16 · 8 min read
Toro mower blades carry OEM numbers stamped near the centre hole and on the deck plate. A correct match pairs that number with deck width, centre-hole type and lift type — not the number alone. Use the OEM number together with your deck size to find a replacement that actually seats on the spindle.
Why Toro blade OEM numbers matter
OEM numbers matter because two blades with the same Toro number can still differ in hole pattern, thickness and lift, and the wrong one will not mount on the mandrel. Toro has used many blade numbers across 21-inch Recycler walk-behinds and 50-inch TimeCutter zero-turns, so matching by number alone leaves the fit to chance. Our guide to matching a blade by OEM number explains the format before you order.
How Toro numbers its mower blades
Toro marks blades with both plain serial-style numbers and hyphenated part numbers, and the style tells you which machine family the blade came from. Walk-behind Recyclers often carry short numbers such as 59534P, while rider and zero-turn decks use hyphenated numbers such as 108-9764-03. Recognising the style stops you from quoting a commercial number when you need a homeowner blade.
| Number style | Typical use | Example | What it signals |
|---|---|---|---|
| Short serial (e.g. 59534P) | 21–22 in Recycler walk-behinds | 59534P | Homeowner, lighter duty |
| Hyphenated (e.g. 108-9764-03) | TimeCutter / Titan riders | 108-9764-03 | 42–50 in decks |
| Long hyphenated (e.g. 131-4547-03) | Titan / commercial zero-turn | 131-4547-03 | 50–60 in heavier decks |
The digits are a house code, not a specification. A 59534P and a 108-9764-03 of different lengths describe different blades, so always pair the number with the deck size.
Where to find the Toro blade number
The number is stamped near the centre hole on the flat of the blade, but grass and rust hide it, so wire-brush the area first. If the blade is gone, the deck or model plate near the discharge chute or under the seat gives the machine model, which is enough to look the blade number up. The owner's manual and Toro's own parts catalogue both list the blade number by model.
Common Toro blade numbers by series
The numbers below are examples of Toro's public part-number styles, shown so you can recognise the format on your own blade. They are for fitment reference only — we are an independent manufacturer and not an authorised Toro dealer.
- 59534P — a common 21–22 inch Recycler walk-behind blade style.
- 108-9764-03 — frequently seen on 42–50 inch TimeCutter decks.
- 131-4547-03 — a Recycler and Titan blade style used across several deck sizes.
- 106-2247-03 — a 42-inch TimeCutter rider blade number quoted by many owners.
- 115-5059-03 — a 50-inch TimeCutter mulching blade number.
- 115-9649-03 — a 60-inch Titan and TimeCutter zero-turn blade style.
If your number is not in this short list, that is normal — Toro 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, which lists the profiles we keep for Toro-fit decks alongside other brands.
How to cross-reference without the original number
Cross-referencing without the old number is straightforward if you record four measurements from the machine instead. Measure the old blade tip-to-tip, note the centre-hole type, check the thickness with a caliper, 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 a correct Toro-fit replacement 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 Toro-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 108-9764-03 blades interchangeable?
No — 108-9764-03-style blades are not interchangeable just because they share the number, because deck width and hole detail decide length and fit. A blade quoted for a 42-inch deck will not suit a 54-inch deck even when the number matches. Always confirm the deck size printed on the machine plate against the blade you intend to fit.
How Toro-fit blades are made to spec
Toro-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 get custom Toro-fit blades made to a sample?
Yes — custom Toro-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 Toro mower blade OEM numbers interchangeable across models?
No — a Toro number only guarantees fit when length, centre hole, thickness and lift also match, which they rarely do across different deck sizes. A blade quoted for a 42-inch deck will not suit a 54-inch deck even when the number is identical. Always confirm the deck width printed on the machine plate.
Where is the blade number on a Toro mower?
The blade number is stamped near the centre hole on the flat of the blade, and on the deck or model plate near the discharge chute or under the seat. 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-Toro blade on my Toro 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 Toro-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 Toro 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 Toro's parts catalogue. Send us those details and we will cross-reference them against our model index.
What is the minimum order for custom Toro-fit blades?
The minimum order for a custom Toro-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 Toro 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.
