The deck of your lawn mower is a crucial component whether you have a zero-turn mower, a lawn tractor, or even a push mower. However, the question of a stamped vs fabricated deck is only relevant to riding lawn mowers. The difference between stamping and fabricating in this context is the process and materials used to manufacture mower decks. Each manufacturer has its own approach, but stamping and fabricating are the two general methods of putting a deck together.
You might notice that some riding mowers are marketed for having either a stamped or fabricated deck and wonder what the difference really is. I’ve been doing some digging into what people say about both and will do my best to shed some light on the question.
Comparing Stamped vs Fabricated Lawn Mower Decks? (Short Answer)
The main distinction between a stamped vs fabricated deck is the build: stamped decks are quite literally stamped into a single piece of metal, and fabricated decks are made up of a handful of pieces welded together. The second distinction is what they are typically used for: stamped decks are more common on residential mowers, and fabricated decks are more often used for commercial grade mowers.
What is a Stamped Deck?
Stamped mower decks are aptly named because they are shaped by pressing steel into big molds. For the most part, these decks are made using an easier to form, thinner gauge steel. As you might imagine, it wouldn’t be very easy to stamp a deck out of super thick material.
Stamped decks are also the most common type of deck used on riding mowers. When you’re shopping around you will notice that most models have a seamless deck that was made in a mold. You might be wondering, are fabricated mower decks better? Well, let me talk about what they are and then I’ll get into the pros and cons of each.
What is a Fabricated Deck?
A fabricated deck is a mower deck made from heavier-grade steel pieces that are welded together. They tend to be a bit larger in general and are known to be very durable.
For this reason, fabricated decks are put on a lot of commercial-grade mowers. You might also find them available as an upgraded deck option for residential mowers. I noticed this was the case for a Cub Cadet stamped vs fabricated deck at least. However, this doesn’t mean that one type of deck is always better than the other. Take a look at the benefits and drawbacks of each below.
Stamped vs Fabricated Decks – The Pros and Cons
There are a number of factors to take into consideration when looking at a stamped vs fabricated deck. To name a few, materials, type of use, cutting quality, and cost are some of the big ones. Let’s open up the conversation a bit more by comparing the two in detail.
The Pros of Stamped Decks
Great Suction and Cutting
Because stamped decks are molded from one piece of material, they have rounded edges that are great for creating suction. Suction is a super important component of a mower deck because it is used to lift blades of grass to deliver a nice clean and even cut. Without enough lift, you could end up with some stubborn patches of grass that need a second pass to get trimmed.
More Affordable
The economic benefit of stamped decks is another great upside. Since thinner material is used and pretty much no welding is needed, the cost of production for these types of decks is pretty low. Of course, a company needs some serious molding equipment, but that expense on their end isn’t a burden to the average property owner. Usually riding mowers with stamped decks have a lower price tag.
The Cons of Stamped Decks
Less Durable
With the use of lighter-duty material comes a shorter lifespan. Some manufacturers may use thinner metal than others, but in general stamped decks are just not as durable as fabricated decks. This means that it can be a lot easier to crumple or bend stamped decks when running over rough terrain. While that might not be a risk for everyone, it’s worth considering. Also, rust can damage stamped decks more severely. Since they’re thinner, rust can eat through them pretty quickly without proper care.
Prone to Buildup
The buildup of mud, trimmings, and other gunk is one thing that can really accelerate wear and tear on stamped decks. Rust is a big threat to mowers that have a ton of buildup full of moisture. Buildup can also lead to bad cutting quality. Hurting suction and the effectiveness of the mower’s blades, you don’t want to let your deck get dirty. Though this issue can be addressed by regular cleaning, it isn’t a very fun job to have to do.
The Pros of Fabricated Decks
Much Stronger
The use of thicker steel and welds makes a huge difference in the strength of fabricated decks. This is a big part of why lawn care professionals and businesses opt for these well-reinforced decks. If you’re out there day in, and day out, you need a mower deck that can handle some regular abuse without getting damaged.
Long-Lasting
The strength of the deck is important to keep a mower alive for a longer time as well. Fabricated decks will outlive pretty much any stamped deck. The construction style of fabricated decks helps with this, but so does the type of material. Since these decks are made with thicker steel, rust is less of a threat. Also, if some especially persistent rust did make it all the way through the wall of a fabricated deck, it would be much easier to repair. Because these decks are made up of many pieces of metal rather than one, some simple welding might be the solution to problems that arise.
The Cons of Fabricated Decks
Fewer Height Options
Fabricated decks tend to be a bit taller so they usually can’t be raised as high as stamped decks. They can get just as low but you might be looking at a difference in maximum height between 3¼ inches on a fabricated deck and 4 inches on a stamped deck. This isn’t always the case, but is a common trend I noticed.
More Expensive
With more material, and more labor involved to put them together, fabricated decks are almost always more expensive. You can justify this expense if you use the mower a ton and will be able to make it last longer than one with a stamped deck. However, that all depends on what your personal use looks like.
Weaker Suction
With sharper angles connecting the corners/edges of fabricated decks, some of the suction is lost. Good old human error becomes a bigger factor when welding and fabrication is being done. While this doesn’t mean that fabricated decks can’t deliver a clean cut, it is a small downside that’s worth considering.
Is One Better Than the Other (My Opinion)
When I was researching these two manufacturing processes, I found myself wondering, is a stamped or fabricated mower deck better? In my opinion, it really depends on what you’re using them for.
To be frank, my stance is that stamped mower decks are a better choice for the typical homeowner. Delivering a great cut at a lesser price, most people probably don’t need the extra toughness of fabricated decks. However, if you have a particularly demanding piece of property, or if you make a living with your mower, fabricated decks are the way to go.

Hey Tom! Thanks for the straight forward info! I’m like you, a lawn care enthusiast who cares for my own property but not much else! I have worked for several landscaping outfits in their lawn care capacity mainly, and I have a brother-in-law who has a side business with a decent amount of lawns to get through on days off from his full-time job. He has a gravely pro model (stand on- which is like, WHY?! to me anyway) lol. But he’s the one who has mentioned stamped decks and fabricated the most – and I have just nodded like I totally understand exactly what he means… which is absolutely not true (until now thanks to you!)
I was checking out Husqvarna Z500 w/the 27HP 60in deck and saw, “10 gauge Fabricated” in the specs for the deck. Being a professional mower, I was just thinking, it’s about time I find out what is the deal with the 2 types…
You nailed it, thoroughly explained but in a simple and easy to follow manner.
I have to agree with your conclusion- my opinion is definitely that A. If you are a homeowner, save the money, get a stamped deck, and enjoy the fact that it really does make a difference in suction with the extra space between the blades and the underside-top of the deck. Can’t tell you how many times I have been on lawns for the pros, on ExMark, John Deere, Kubota, Husky, Gravely, Skag (beast right there!) But my favorite was the Kubota actually – Worked for the grounds crew at Loon Mtn, and had “my own” – boy that cut NICE. ExMark was nothing to be overlooked either – the LazerZ X-Series. Whew that was too fast! 15mph- not up here! If you can sit in there and hold the line at 7-8mph you are the best operator that I will have known- just too many grade and pitch changes- not smooth flat golf course in Florida type of terrain – white mountains of NH – we had lawns that were too steep for a big boy mower- literally would have 3 guys with push mowers– several properties like that actually… So ExMark was nice, Husky was good but I didn’t have enough time on it to get used to the 16 cutting steps and the weight… Kubota- Again, all-time favorite wonder of a machine to operate. It was the ZD series model 1511. 30.8HP liquid cooled 4cyl diesel engine, 72inch deck 1-5″ cut range in ¼” increments turn dial to set– was just so slick- the seat was like a throne for a king- air-ride suspension seat with reclining, adjustable lumbar support- and the seatbelt, plus arm rests in the elevated seat just made me feel so high up- unlike ANY other mower since- even climbing up from the ground to the mower deck then at least a foot or more up to the platform for your feet- then the tiered set-up of the suspension in the seat — I mean the rear tires were 26″×12.5″ front were 15″ or 15.5″- it was a monster. 11mph fwd, 6mph in reverse… idk what to say – that was the cat’s meow! My supervisor, Mike, was in hot water when the budget committee saw the bottom line — that machine goes for $25,500 MSRP with no extras- add a few options, a warranty and 28K is about the price tag… But that’s not the norm – kubota makes great mowers for a wide range of $$$ – $4500-5000 low LOW end. And then there’s everything in between including a lot of great commercial mowers well equiped for under 12 grand. That was sooo expensive because of the 31HP diesel engine, the hydrostatic 2step transmission, the deck- 72″ was just great for the base of the ski area, but get in the smaller areas and i will take a 52-54″.
Wow I have been going on and on! Sorry about that Tom. Have a great weekend, and thanks again for the information!! A+ Buddy 👌🏽👍🏽
