Wider Cut, Larger Bag, Fewer Interruptions
The maths of mowing is simple: a wider cut means fewer passes. The Hyundai HYM18150SPX stretches the cutting width to 18” / 46cm, letting you cover more ground with each stripe. Combined with a 60L collection bag, you’ll spend less time emptying and more time making progress.
This is a self-propelled machine with the same 139cc engine found in the smaller 17” model, but paired with a larger deck and bag. The result is a mower suited to medium-sized gardens where the extra capacity and coverage make a noticeable difference to how long the job takes.
Key Benefits
Cover More Ground Per Pass
An 18" / 46cm cutting width means roughly 7% more coverage per stripe compared to a 17" mower. Over a medium-sized lawn, that adds up to fewer passes, less time, and less fuel used.
Empty the Bag Less Often
The 60L collection bag holds 50% more than the 40L version. Fewer trips to the compost heap or green bin means you maintain your rhythm and finish faster.
Four Cutting Modes
Bag for a tidy finish. Mulch to return nutrients. Side discharge when the grass is long and dry. Rear discharge for quick coverage. The HYM18150SPX handles all four, so you can adapt to conditions.
Who Is This For?
Ideal for:
Owners of medium gardens (approximately 500m² to 1,000m²)
Those who find themselves emptying a 40L bag too often
Gardeners wanting self-propelled assistance and mulching capability
Users upgrading from a smaller petrol or battery mower
Not ideal for:
Small lawns where a compact mower is easier to manoeuvre
Very large lawns over 1,000m² (consider a 20" or 22" model)
Those who prefer electric start (see HYM18150SPEX)

User Manual
Always read the user manual before use and always follow the safety instructions. Operators must always wear proper Personal Protective Equipment (PPE)—including non-skid safety footwear, eye protection, ear defenders, and long trousers—and keep children, pets, and bystanders at a safe distance of at least 15 meters. Because exhaust gases contain toxic, odorless carbon monoxide, the petrol engine must only be operated outdoors in well-ventilated areas away from doors, windows, and vents. Handle fresh straight unleaded petrol with extreme caution outdoors, avoiding smoking, overfilling, or refueling while the engine is running or hot, and ensure 4-stroke engine oil (SAE30 or SAE 10W-30) is filled to the upper mark on the dipstick. Inspect the work area for foreign objects, do not operate on wet ground or slopes steeper than 15 degrees, and keep hands and feet clear of the rotating blade. Always operate the mower standing firmly behind the handle, disengaging the Operator Presence Control (OPC) lever to stop the engine instantly in an emergency, and always disconnect the spark plug HT lead before performing maintenance, clearing blockages, or adjusting the cutting height.
