Thatch builds up in any lawn that gets regular use. Left alone, it blocks water, air, and nutrients from reaching the roots — and no amount of feeding or watering fixes the underlying problem. The Hyundai HY40CSC38 is a 40V cordless 2-in-1 that removes thatch with its scarifier blade (rigid steel tines) and aerates compacted soil with its raker blade (spring tines), both across a 38cm / 15" working width. Five height positions from -12mm to +6mm let you set the depth to match your lawn's condition, and a 45-litre collection bag captures the material as you work. No petrol, no cable, and a polypropylene deck that won't rust through seasons of use.

Remove Thatch and Aerate in the Same Session

Most lawn problems stem from either thatch build-up or soil compaction — sometimes both. The two interchangeable blade types mean you can scarify and aerate without changing machines or booking two separate sessions. Work down through the thatch first, then follow up with the aerator to open the soil beneath.

Set the Depth to Match Your Lawn's Condition

Five height positions span -12mm to +6mm. Start at a shallower setting for a lawn that's been maintained regularly, and work deeper as conditions allow. The +6mm position is useful for a lighter pass at the start of the season before pushing deeper in subsequent runs.

A 45-Litre Bag Means Fewer Emptying Stops

The large collection bag captures removed thatch on the move, reducing how often you stop to empty it. The fabric and polyethylene construction makes it easy to empty and shake clean.

Cordless Freedom on Small and Medium Lawns

Two 4.0Ah batteries provide runtime suited to small and medium-sized lawns. The operator presence control cuts the motor the moment you release the handle, and the tool-free assembly means it's ready to use straight from the box.

The Hyundai 20V Battery System - No Cables, No Petrol, No Pollution

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).
