Hyundai 18" / 46cm Self-Propelled Petrol Lawnmower, 139cc, Mulching | HYM18150SPX

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)
