Gravely Mower Blades: Deck Size & Fitment Guide
2026-11-01 · 8 min read
Gravely mower blades are matched by deck width, centre-hole type, length and lift — not by the model name alone — because Gravely commercial decks run several widths on shared spindle patterns. A correct replacement seats on the spindle and cuts cleanly without buzzing, scalping or throwing clippings unevenly.
What part numbers do Gravely mower blades use?
Gravely 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 to a single machine. Gravely is part of the Ariens family, which is why several Gravely-fit blades also carry Ariens fitment and share the same spindle geometry across the two 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 from any supplier.
| Catalogue number | Deck width | Length | Centre hole | Lift type |
|---|---|---|---|---|
| 038-2007-00 | 60" | 21" | Round | High lift |
| b0ft2jlrhq | 52"–54" | 18.5" | Round | Mulching / high lift |
| 422719 | 42" | 21" | Round | Mulching |
These three catalogue blades list Gravely among their fitment brands, so they are the reference points for the deck widths Gravely commercial mowers most often run. We are an independent manufacturer and not an authorised Gravely dealer, so none of them are our own house numbers.
How do I match a Gravely blade to my deck?
Match a Gravely blade by recording four facts — overall length, centre-hole type, thickness and lift — then comparing 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 Gravely commercial deck?
A high-lift or mulching blade suits most Gravely commercial decks, because the heavy-duty spindles and faster ground speeds favour a profile that lifts clippings into the chute rather than letting them pack. Mulching blades trade some lift for fine recutting, so pick by what you do with the clippings.
| Blade type | Suited to | Trade-off on a Gravely deck |
|---|---|---|
| High lift | Bagging, tall or wet grass | Can throw clippings harder than needed |
| Mulching | Recycling leaves and fine clippings | Needs slower ground speed |
| Notched high lift | Bagging plus durability on grit | Heavier; slightly more draw |
The 038-2007-00 (60-inch high lift) and b0ft2jlrhq (52–54-inch mulching) above are the two Gravely-fit profiles we stock for full-size commercial decks. A 42-inch mulching blade such as 422719 covers the smaller Gravely Pro-Turn and walk-behind widths when your deck is under 48 inches.
Are Gravely blades interchangeable across deck sizes?
Gravely 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 60-inch deck will not suit a 52-inch deck even when the family prefix matches.
For example, 038-2007-00 covers the 60-inch high-lift range, while b0ft2jlrhq is the 52–54-inch mulching 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 Gravely-fit blade use?
A Gravely-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 of daily use.
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 Gravely-fit blades made to a sample?
You can order custom Gravely-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 Gravely and Ariens blades the same?
Gravely and Ariens share a parent company and many spindle patterns, so several blades fit both brands, but they are not identical across every deck. Confirm deck width, length and centre hole before swapping, because a number that fits an Ariens 52-inch deck may not fit a Gravely 60-inch deck even within the same family.
How often should I replace Gravely mower blades?
Replace Gravely blades when the cutting edge shows nicks deeper than a coin, when the ends are worn past the original width, or when you see cracks near the centre hole. Commercial decks under daily load typically need a fresh blade each season, with mid-season sharpening in between rather than waiting for failure.
Can I use a universal blade on a Gravely deck?
A true universal blade rarely fits a Gravely spindle correctly, because the centre hole, length and lift must match the deck geometry exactly. Always match the four measured dimensions to a Gravely-fit profile instead of assuming a generic blade will seat and balance safely.
Are your Gravely-fit blades original Gravely parts?
We are an independent manufacturer and not an authorised Gravely dealer, so our blades are not original factory parts. They 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.
What is the minimum order for custom Gravely-fit blades?
The minimum order is 300 pieces per blade profile, which covers the setup and heat-treat run for a made-to-sample blade. Custom steel such as SK5 can be quoted, and mixed profiles can be combined across a single production window to reach the minimum.
