Before investing in a new lawn mower to replace the old broken one, you should consider the options that can last for a long time.
You must evaluate the factors, such as mulching options, blade availability, and propulsion systems. Also, it’s essential to check out the material of your machine deck.
While you may come across plastic decks, aluminum and steel versions are much more popular.
Although plastic is a more affordable option, it’s best to opt for aluminum and steel decks for long-term value.
Which is better: lawn mower steel deck vs. aluminum? If you are unsure what to pick, read this article to learn about the pros and cons of each type!
Let’s get started!
What Are The Differences Between Lawn Mower Steel Deck And Aluminum?
The deck of a mower is the component that can protect you and your machine engine from the blade and flying dirt while you use your device.
Therefore, this part is often constructed from a long-lasting material that can resist rust and corrosion.
Moreover, it should be strong enough to withstand the force of stray particles that the blade may kick up.
Besides plastic decks, you may find aluminum and steel versions. Below are the main differences between the two. Let’s take a closer look!
Lawn Mower Steel Deck
Without a doubt, steel is among the most well-liked materials used to manufacture lawn mower decks due to its incredible durability.
Steel decks can withstand impacts. As a result, high-end lawn mower manufacturers frequently pick them.
These steel decks can endure scrapes, crashes, and bumps often occurring with commercial mowers.
As such, they will undoubtedly be capable of trimming your yard. These decks can continue to look amazing for a very long time despite the damage they may sustain.
Most manufacturers use powdered paint to coat the decks, which offers aesthetic and rust-prevention benefits. You can watch this video to get a detailed tutorial:
Steel has drawbacks, just like all other materials. You must consider the steel type used for your deck.
Impact-resistant ability is among the most persuasive reasons to purchase a lawn mower with a steel deck.
However, you only get all the benefits of this material if the deck is manufactured of thick steel.
Some lawn mower manufacturers may cut costs in the production process, so they use thin steel, which makes the deck not durable.
On the other hand, this material is heavy. Thus, if you don’t take the impact-resistant ability seriously, you can opt for a stamped steel deck.
Last but not least, steel is prone to rusting over time. While you can delay this deterioration with good maintenance, corrosion is unavoidable.
Lawn Mower Aluminum Deck
Several modern lawn mower decks are made of aluminum alloy, a lightweight substance.
While you can see large mowers with aluminum decks, this material is ideal for smaller push machines.
Moreover, aluminum alloy has the advantage of not rusting, besides its lightweight characteristics.
For homeowners who utilize machines with an integrated deck cleaning mechanism, it’s a significant benefit.
These mechanisms often entail attaching a nozzle to your lawn mower deck and spinning the blade to clear grass lodged underneath the deck.
Aluminum decks’ most significant shortcoming is that they aren’t very robust. They are prone to crumpling, bending, and cracking after several hits.
Generally, aluminum decks are relatively reliable and require little maintenance, which is ideal for personal use.
Comparing And Contrasting Steel Vs. Aluminum Deck
Are you confused between steel and aluminum decks? Consider the main points:
In this round, steel decks are the champion. They can effectively endure impacts, bumps, scrapes, and crashes.
On the other hand, aluminum is not as sturdy as its counterpart. Thus, it may bend, crack, or crumple after several hits.
While steel is susceptible to rusting gradually, aluminum decks do not suffer from this problem.
Thanks to its rust-resistant ability, steel doesn’t require much special maintenance.
However, providing proper and reasonable care for a steel deck is essential as it’s easy to get rust.
If you are looking for a lightweight lawn mower deck, you can’t go wrong with the types made of aluminum.
These options are much lighter than their steel counterparts. As a result, you will find it easier to push your machine around.
Comparison between the two types
Which Deck Is The Best For You?
As you see, these deck options come with benefits and drawbacks. Therefore, the final verdict depends on your requirements and preferences.
For instance, if you merely plan to use your machine to trim the lawn in your yard, selecting either aluminum or steel type is okay.
If you purchase a machine without self-propelling mechanisms, picking an aluminum deck is more suitable because it can lessen the heaviness you must push around.
Do you provide professional lawn care? It’s a good idea to use both types of lawn mower decks.
Aluminum decks are ideal for push machines in small areas with little impact risks. Additionally, you can use a lawn mower with a steel deck for places with rocks or bumps.
This way, you won’t have to repair the deck constantly because this material is sturdy and can withstand impacts.
The final verdict
What Is The Best Material For A Mower Deck?
The common materials used to manufacture a lawn mower deck include plastic, steel, and aluminum.
However, steel is the best option. High-end manufacturers often use this material for their mower decks.
Generally, steel brings more benefits than others. For instance, it provides outstanding strength and impact-resistant ability.
Is A Steel Mower Deck Better Than Plastic?
The short answer is yes! Steel decks will have a longer lifespan and are sturdier than plastic.
With impact resistance, the machine with a steel deck can easily handle bumps or rocks while mowing your lawn.
How Thick Is The Steel On A Mower Deck?
The thickness of this metal on most lawn mower decks should be from 7 – 10 gauges. Most decks can work well if you plan to mow in your private yard. You should consider the features of the deck instead of its thickness.
The Bottom Line
Steel and aluminum decks have pros and cons. Thus, it’s relatively challenging to decide the best option.
After reading this article, we hope you can decide which lawn mower deck you want to purchase, depending on your needs and interest.
If you want a machine for regular use, you can’t go wrong with the model with an aluminum deck because it requires little maintenance and performs well in your yard.
On the other hand, a mower with a steel deck may be more suitable for commercial mowing as it’s sturdier and more durable.
The final verdict is up to you. Happy shopping!
