Blades look alike. Two blades of identical length can differ in centre hole shape, thickness and offset — and the one that does not fit will not fit whatever you do to it. The fastest way past all of that is a part number.
On the old blade. Most original blades carry a stamped number near the centre, on the flat. Wire-brush the area first; decades of grass and dirt sit right where the stamping is.
On the machine. Look for a deck or model plate on the mower housing, usually near the discharge chute or under the seat. That gives you the machine model, which is enough to look up the blade number.
In the manual or the dealer's parts diagram. If you have neither the blade nor the plate, the machine model plus deck width is usually enough.
On the OEM's own parts site. Manufacturer parts catalogues are searchable by machine model and will list the blade part number directly.
Numbers vary by manufacturer, and recognising the house style helps you avoid typos when you write to a supplier.
742-04308. Six digits, a hyphen, five
more. The same blade often appears with slightly different suffixes across
model years.038-0005-00. Three groups separated by hyphens.72511-VL0-S00. A five-character code, then two two-character
groups.134149, 187256. Common on MTD-family decks, and
the ones most often mistyped.A cross-reference is a claim that blade A is a functional substitute for OEM number B. Good ones account for length, width, thickness, centre hole and lift type — not just the number.
Two things to watch:
The same OEM number can appear on more than one blade in our range. That is
not a mistake. When a manufacturer uses one part number across decks with
different lift requirements, the number alone does not identify which blade you
want. This is why we list the blade type alongside the OEM number — a
187256 in high-lift is a different product from 187256 in mulching.
Kit numbers and set numbers are not blade numbers. Some listings sell a three-blade set under a kit number, or a multi-fit set that covers several machines without a single OEM number. If a number returns nothing anywhere, check whether it is a kit rather than a component.
Include any of the following, and most of the work is done before we reply:
Add quantity and destination port or country, and you will get fitment, price and lead time in one reply rather than three.
Our model library is searchable by OEM part number and lists the blade type, deck size and centre hole for each one — currently 59 models, covering Ariens, Toro, John Deere, Husqvarna, Scag, Exmark, Kubota, MTD, Cub Cadet, Honda and others.
Brand names are used for fitment reference only. We are an independent manufacturer and not an authorised dealer for any of these brands.
If your number is not listed, it does not mean we cannot make it — it means we need one more detail. Send it across and we will confirm.
