Engine & Components

Giantz has a small range of lawn mowers, all targeted at maintaining city lots.

Their petrol mowers have medium to average power, standing at around 140cc. However, they have chosen 4-stroke engines to give them strength when mowing thick grass. As we’ve already mentioned, lawn mower engines can be either 2-stroke or 4-stroke. The first category means the engine doesn’t have a dedicated lubricating system, so oil and petrol have to be mixed together before filling the tank.

PRO TIP:  Giantz uses 4-stroke engines on their petrol mowers

On the other hand, 4-stroke engines have a lubricating system and you’ll need to fill both the oil reservoir and the fuel tank. According to the Small Engine Warehouse team:

PRO TIP:  “A 4-stroke engine has more torque, the engine is quieter and more reliable, it lasts longer than a 2-stroke engine and is much more fuel efficient" – Small Engine Warehouse [1]

While seeing a lawn mower with a 4-stroke engine is always positive, we’re not thrilled with the fact that Giantz doesn’t disclose what brand they’ve chosen. Other lawn mower manufacturers at this price point mention their engine of choice, but Giantz doesn’t do anything of the sort. When taking this and the retail price into account, the likely answer is that they’ve chosen to go for cheaper engine brands in order to cut costs. We’d rather know what kind of engine we’re buying since it’s the decisive factor when getting the job done.

When it comes to the rest of the components, Giantz tends to go for the cheaper option as well. As such, their lawn mower’s decks are all made of plastic, even in the somewhat "higher-end models". Plastic decks tend to keep their colour better -since they’re usually dyed instead of painted- but they are more brittle than their steel counterparts. On the other hand, the plastic wheels can feel flimsy, especially if you’re mowing an irregular lawn.

Overall, we’re not loving the build of these mowers, although they do the job. We’re giving Giantz 3 out of 5 in this category.

Size 4/5

If you’re looking for an extra small mower, this brand might be the right choice. Both their petrol and electric mowers stand on the smaller end of average, making them great for smaller spaces. Their largest petrol mower features a 17-inch deck. In contrast, Giantz’ smallest electric mower has an incredibly narrow 13.5-inch deck, which is around 35 cm.

For homeowners with a narrow nature strip and a small yard, these smaller sizes might be a good compromise between practicality and storage space. However, this brand doesn’t offer much more in terms of sizing: beyond foldable handles, you’ll need relatively ample space to keep your mower inside. If you’re really low on storage, it might be worth it to look at foldable mowers or even ones that could be stored upright.

In spite of these shortcomings, customers are pleased with the weight of these mowers. Most brands manufacture push mowers that surpass the 35-kg mark. In fact, some lawn mowers can weigh up to 45 kg, making them hard to push around. It becomes even more difficult to deal with these traditional mowers if you have irregular terrain or just don’t have the upper-body strength to push it. Electric mowers are significantly lighter than their petrol counterparts since the oil and fuel add even more weight to the ensemble.

To fix this, manufacturers have crafted two solutions: either use a self-propelled system or create lighter mowers. Giantz doesn’t offer any self-propelled mowers in Australia, but their products tend to weigh less than average. Both their petrol and electric mowers are relatively easy to handle and all weigh less than 32kg, so many customers prefer the brand when needing lightweight garden tools.

Of course, the lighter weight comes at a price. For example, the fuel tank on their petrol engines is smaller than others at this price point, so you might have to fill it up midway. On the other hand, the electric mowers only carry 2.0 Ah batteries, which hold less energy than the more common 4.0 Ah lawn mower batteries.

Since we appreciate the design that went into making these mowers so portable and small, we’re giving Giantz 4 out of 5 stars.

Features & Ease of Use 3/5

In general, customers consider this brand has plenty of features, especially taking into account the price point. Overall, we’d say these lawn mowers are average at best, but there are some key differences with other models at this price point that might deter you from choosing it.

The main shortcomings when it comes to ease of use come with their electric mowers. As we already mentioned, these mowers come with two 2.0 Ah batteries to power their cordless models. This is lower than the mainstream 4.0 Ah battery other models tend to have. Plus, it means you won’t be able to switch the original batteries for a single 4.0 Ah one.

Of course, the choice of the smaller batteries makes the entire mower lighter, which is something many buyers look out for. However, it also means it has a shorter running time. While Giantz doesn’t disclose a minimum run time, customers mention they can get around 30 minutes on a full charge, using both batteries at the same time. If you have a modest lawn with very little grass to cut, 30 minutes will buy you barely enough time to trim. In any other context, you’ll have to stop midway to charge.

Giantz electric mowers are fast charging, but their batteries still charge significantly slower than higher-end brands. For example, their 2.0 Ah batteries reach a full charge in 60 minutes, while other brands we’ve reviewed before take half the time for the same type of battery. At this price point, we could live with the lower charging rate, but customers complain after some weeks their batteries start losing their fast charge. In those cases, batteries need to stay hooked for around 3 hours, while still counting 30 minutes of active time.

Overall, we’re not particularly impressed with their electric mowers, considering they are so narrow you’ll have to do more laps around the lawn.

It’s also worth mentioning all Giantz mowers have equally-sized wheels at the rear and the front. While the wheels are relatively small standing at 6-inches, we don’t appreciate the rear wheels not being larger. At this point, it’s almost an industry standard to use larger rear wheels. This makes the entire mower easier to move on uneven ground, which is something to consider if you’re dealing with hills.

Finally, it’s worth mentioning the handles on these mowers aren’t adjustable. This is something the end user could get used to but might be bothersome if you’d like a younger teen or a short person to be in charge of mowing.

All in all, their small size and lightweight makes these lawn mowers easy to handle. It would be nice to see other features, like adjustable handles, but at this price point, this is good enough. We’re giving Giantz 3 out of 5 stars.

Warranty, Maintenance & Durability 1/5

While all models come with a user’s manual, customers complain the latter is almost unreadable: with black pictures and confusing instructions, first-time mowers might have a hard time assembling and maintaining their Giantz.

When it comes to repairs and maintenance, you’ll be hard-pressed to find official spare parts. Customers complain the sellers don’t have spare parts available, so in order to fix anything, you’ll have to sub with other brands. Many reviewers mention their mowers have lasted a while, but maintenance can be difficult because of the lack of spare parts.

On the other hand, this brand doesn’t have a proper warranty to speak of. There is no official manufacturer’s site or dealership in Australia, so all products are sold through third-party sellers. As such, you’ll have to figure out your sellers’ warranty policy before purchasing. Make sure the seller you select has a good reputation on the platform, or you could end up with a faulty mower and nowhere to return it.

PRO TIP: Giantz doesn’t have an official manufacturer in Australia

Even though these mowers tend to handle work well, they’re made for light domestic use and repairs are difficult to accomplish without official spare parts. Plus, since manufacturer’s warranty is non-existent you have to do your own research and pick your retailer carefully. Because of these shortcomings, we’re taking off 4 stars.

Price 4/5

This is where Giantz shines. These are very affordable models, although the low price comes with certain compromises. This brand’s electric mowers are priced drastically lower than other entry-range options, but it shows when it comes to performance and size. These mowers are very small, fitted to keep nature strips or very small lawns in good shape. However, anything larger than that and you’ll have to charge the battery mid-mowing, which will make the entire process longer.

On the other hand, their petrol mowers are good enough and, at this price point, a nice compromise if you’re dealing with a small space.

We’re giving this brand 4 out of 5 in this category.


Our Top Picks From This Brand

This brand has a very limited range, so our selection is based on customer satisfaction. Here are the model’s customers have liked better:

17-Inch Giantz Petrol Lawn Mower

This straightforward mower has the essentials needed to take care of a small city lot with ease. Its small size ensures you can reach every corner while a good-enough engine gets the work done. Their 17-inch mower features a 139cc 4-stroke engine that doesn’t take up much petrol, and most customers are reasonably satisfied with its performance.

On the flip side, the wheels are very small for a mower. Standing at 6-inches, it could make pushing your mower harder, especially if you’re dealing with any sort of hill. Plus, the rear wheels are the same diameter as the front ones, so you won’t get extra traction from them.

Specs

  • 139cc 4-stroke engine
  • 2 function: Bagging and side-discharging
  • Plastic 17" deck
  • Cutting height: 25mm to 75mm

40v Giantz Cordless Electric Mower

Another pretty affordable option, customers enjoy this electric mower for its quietness and the fact it comes with 2 2.0 Ah batteries. Many users also like that it is relatively lightweight, although this is common when it comes to cordless mowers.

This a very narrow mower and at only 13.5 inches -or 35cm- wide, you’ll have to loop several times around the yard to get everything cut. On the flip side, it comes with 2 fast-charge batteries that can be ready to go in one hour. This is longer than with other models we’ve reviewed at a slightly higher price point but still workable. One charge lasts around 30 minutes, and customers complain that after a couple of charges, the fast charge doesn’t work anymore. In those cases, you’ll need to charge it for around 3 hours.

Specs

  • Cordless 40v electric mower
  • Foldable handles
  • Push button start
  • 13-inch plastic deck

Don’t Buy If…

While this is a good enough option for many, think about other brands if you:

  • Have an irregular lawn: This brand uses relatively flimsy, lightweight wheels on their mowers. Plus, they all stand at around 6 inches in diameter, which makes it harder to push over any hill you might deal with.
  • Want a self-propelled mower: None of Giantz’ models are self-propelled, meaning you’ll have to push around the mower on your own.
  • Need a sturdy mower: As we already mentioned, Giantz chose to use plastic for the deck and relatively thin alloy for the handles. If you treat your lawn mowers a bit rough, you’ll end up breaking or denting it.
  • Want a strong warranty: Since this brand doesn’t have a proper website or official retailers, and instead is sold through 3rd-party sellers, the warranty depends on each retailer. If you’d rather have a bulletproof manufacturer’s warranty, you’ll have to look elsewhere.

The Verdict

Overall, we don’t recommend these lawn mowers except if you have a very small, flat area in need of occasional mowing. At this price point, there are other petrol mowers with a stronger warranty, while you can find decent electric mowers for up to 100 AUD more.

If you have anything larger than a couple of metres of yard, the small deck size might make cutting your lawn a bigger chore than it needs to be.
