Product Details
Description
Not every garden needs a large mower. If you have a courtyard lawn, a back garden under 150m², or a series of small patches to maintain, the Hyundai HY20CLM33 3-in-1 mower cuts to exactly the size of the job. Five height positions from 25mm to 65mm and a 32-litre rear collection bag handle the basics cleanly, while the folding handle keeps storage simple. A mulching plug is included and pre-fitted under the rear flap, so you can switch from bagging to mulching whenever you want to return clippings to the lawn. Lightweight at 10.28kg, it's easy to carry up steps, through gates, or between separate garden areas.
3-in-1 Machine
Three handy functions in one package. Choose from cutting and drop, collect or mulch.
No Cables. No Petrol. No Pollution
Right-Sized for Small Lawns — Not Over-Engineered
At 33cm / 13" wide, the HY20CLM33 is sized for lawns that a larger 38cm or 43cm machine would feel excessive on. It manoeuvres easily around flower beds, into corners, and through narrow gate openings where wider decks can't fit.
Five Cutting Heights for Year-Round Use
Height positions from 25mm to 65mm let you maintain the lawn through every season. Set higher in summer to protect the grass root zone, and drop lower for a more formal cut when conditions allow.
Grass Comb
Helps produce a cleaner, more accurate cut and allows you to mow right up to the walls, borders and edges.
Easy to Store, Easy to Move
The folding soft-grip handle reduces the footprint of the machine to fit in compact storage spaces. At 10.28kg net, it's light enough to carry through the house or lift into a car boot for use elsewhere.
The Hyundai 20V Battery System
All tools in the Hyundai 20V cordless range share the same battery platform. One battery works across every tool in the collection — so batteries you already own are ready to use straight away, and additional batteries charged for one tool are available for any other.
Several tools in the range, including this one, run on two 20V batteries in series to deliver 40V. These dual-battery tools are part of the same system and use the same 20V batteries as the single-battery tools.
Please note: 20V 2nd Generation batteries (SKUs starting HY20 or HY40) are not compatible with 1st Generation 20V MAX batteries (SKUs starting HY21). and m

Frequently Asked Questions
How large a lawn can the HY20CLM33 handle?
The HY20CLM33 is best suited to small lawns up to approximately 150m².
Is this mower self-propelled?
No, the HY20CLM33 is a push mower. It is lightweight enough at 10.28kg that pushing is comfortable on flat to moderately uneven ground.
Does the HY20CLM33 battery work in other Hyundai 20V tools?
Yes. The 20V 4.0Ah battery is part of the Hyundai 20V battery system and is compatible across the 20V cordless range.
How does rear collection work?
The 32-litre collection bag attaches to the rear of the machine and catches clippings as the blade cuts. When the bag fills, remove it, empty the contents, and reattach. The indicator on the bag makes it easy to see when it needs emptying.
Can the HY20CLM33 mulch grass clippings?
Yes. A mulching plug is included with the HY20CLM33 and comes pre-fitted under the rear flap from the factory. Remove the rear collection bag, fit the plug in its place, and the mower will mulch clippings back into the lawn instead of bagging them.
What warranty does the HY20CLM33 come with?
The HY20CLM33 comes with a 3 year warranty for home users and a 1 year commercial warranty.
Are the batteries compatible with other Hyundai 20V cordless tools?
Yes, with one important distinction. The 20V battery included with this product works across all tools in the Hyundai 20V 2nd Generation cordless range (SKUs starting HY20 or HY40). If you already own other tools from this range, your existing batteries will work straight away.
However, 2nd Generation 20V batteries are not compatible with the 1st Generation 20V MAX range (SKUs starting HY21). If you own older Hyundai cordless tools, check the SKU before assuming the batteries will interchange.

Really pleased with it . But one suggestion the bottom handle screw is difficult to line up and dont think it will last to long.
R
Very easy to put together. As the battery was showing some charge I cut my grass straight away. The mower is lightweight and easy to use, perfect for me. The order process was very easy, I was kept informed by email of the delivery and am delighted with my new mower.

A very useful mower for small areas that my robot mower cannot get to and a small strip of grass outside my property.kj,

Good for the money

Surprisingly good mower!
I bought this to replace a mains powered one as my wife kept getting tangled in the cable!
It arrived quickly, was very easy to assemble, the battery was partially charged so I was able to test it as soon as it was built.
It cuts a bit high, so I have lowered the blade a little.
The mulch plate is fitted so you may be surprised to find it doesn't send any grass to the collector, just remove it and it works fine.
Very happy with my purchase, a great mower for the price.

I have now used this twice without the collection bag and I am very happy with the performance. The lightweight makes it easy to carry and access areas of grass which are not accessible to heavier wheeled lawnmowers. Recharging the 4Ah battery is relatively slow. I am not convinced by the height adjustment detente spring. This does not seem to be a good design point. These latter two items are why I don't award it 5 stars.
