Petrol Lawn Mower for Large Lawns

The HYM510SP is a petrol self-propelled lawn mower from Hyundai. With a powerful Hyundai IC200VE 196cc engine with low fuel consumption, it is ideal for medium to large-sized lawns. 

For the perfect, tailored cut on your lawn, the HYM510SP can be easily adjusted between its six different cutting heights - from 25mm to 75mm - by using a single height adjusting lever, giving you complete control over your lawn care needs.

Self-Propelled Petrol Mower

With rear wheel drive, which is especially good for handling uneven terrain, this mower also features a self-propelled system - no pushing required! Mowing has never been easier.

508mm Cutting Width

With an extra-wide cutting width of 508mm / 20", this mower is ideal for medium to large lawns and gardens. 

The HYM510SP's large 70L grass collector bag features a high airflow plastic top with a level indicator to ensure maximum grass pickup. As it's so large, it also means you'll spend less time having to empty the cuttings, reducing your overall mowing time.

Safe and Easy To Use

Designed with your safety in mind, the HYM510SP includes OPC (Operator Presence Control) technology that ensures the engine will not run if you let go of the handle.

With minimal assembly required and 600ml engine oil included, you can be up and running in minutes to get that first cut on your lawn done as quick as possible!

After use, the deck can be quickly and easily cleaned underneath by connecting your garden hose and swilling the bottom of the deck with water.

The soft grip handles can be folded forwards oven the main body for extra-compact storage to save space in your garden shed or garage. 

3 Year Warranty

As with all of our Hyundai Lawn Mower range, the HYM510SP comes with our Hyundai 3 year home-use* / 1 year commercial warranty* (terms apply) for added peace of mind.

Great Lawnmower

I recently bought the Hyundai Petrol lawnmower HYM510SP and it is absolutely stunning. It was a breeze to put together and there are lots of helpful videos available. The price was great for such an attractive product. I haven't used it yet, but I'm confident I won't be let down after all the research and reviews I read!

Margaret Noble
Impressive performance

This powerful machine has me amazed - its swift engine had me in awe until I realized where I was. Its substantial build is reassuring and I appreciate the electric starter and convenient single handle height adjustment. The spacious grass collector is highly practical and I'm looking forward to years of use.

Sarah Towner
Fantastic machine

Quick shipment and securely packaged. Put together in half an hour and functioning. Started with the third tug of the string. Hoping for many years of enjoyment.

Stuart Munro
Great Product!

I'm incredibly delighted with my first cut using this amazing product! It arrived quickly, only a few days after I had placed my order.

Jaqueline Parsons
Just the job

I replaced my 20 year old mower with this one, and it arrived quickly and well-packaged. It only took me half an hour to assemble, and it started on the third pull of the cord. Now I'm just waiting for my lawn to dry so I can make my first cut - I'm really looking forward to it!
