Why buy the Mountfield SP185 Li 18″ Cordless Lawn Mower (Kit)?

  • Self-propelled drive system for effortless mowing
  • Durable 46cm (approx. 18″) steel cutting deck
  • Powerful and efficient 1.3kW brushless motor
  • Includes one 48V 5Ah STIGA ePower battery and charger
  • Large 60-litre hybrid grass collector with ‘full’ indicator
  • Ideal for medium-sized UK gardens up to 550m²

The Mountfield SP185 Li offers the performance of the brand’s popular SP185 petrol mower in a modern, convenient battery-powered package. Designed for homeowners looking to move away from petrol and cables, this self-propelled mower delivers hassle-free lawn maintenance with impressive results. It’s an excellent choice for gardens up to 550m², providing the freedom to mow anywhere without restriction.

Powerful & Efficient Cordless Performance

At the heart of the SP185 Li is a powerful 1.3kW brushless motor, driven by a 48V 5Ah STIGA ePower battery. This combination provides ample power for both the cutting blade and the self-drive function, ensuring a consistent and efficient cut even in tougher conditions. As a kit, the mower comes supplied with one battery and a single fast charger. For those with larger lawns or who require longer runtimes, the mower has space for a second battery, which can be purchased separately.

Superior Cutting & Collection

Equipped with a robust 46cm (approx. 18″) steel deck, the SP185 Li is built for durability and performance. The cutting height can be easily adjusted through six positions, from 22mm to 65mm, using a single centralised lever. An integrated anti-scalp comb at the front of the deck ensures a smooth, even finish on undulating ground. The mower offers great versatility with collecting and rear discharge options, and also includes a mulching plug to finely shred clippings and return them to the lawn as a natural fertiliser. The large 60-litre hybrid grass collector features a ‘bag full’ indicator, reducing the number of stops to empty.

Designed for User Comfort

The self-propelled rear-wheel drive system makes mowing effortless, especially on gentle slopes or across larger areas, moving at a comfortable forward speed of 3.7 km/h. The ergonomic handlebar includes a dual-hand switch for safety and comfort, and is both adjustable and foldable for easy, space-saving storage. Grooved wheels on ball bearings ensure smooth travel across the lawn, and a front handle makes the mower easier to lift and carry.
