The Masport 150 ST SP — Practical Mowing for Small to Medium UK Lawns
The Masport 150 ST SP self-propelled lawnmower brings straightforward performance to homeowners looking for a reliable mowing solution for small to medium-sized gardens. Powered by a robust Briggs & Stratton 300 E Series engine (125cc), this petrol lawn mower is suited for both level lawns and those with gentle inclines, removing physical strain thanks to its self-propelled design.
Key Features for Everyday Lawn Care
The 16″ (42cm) steel cutting deck provides a durable, rust-resistant platform for years of use, while the bar blade delivers a neat, rotary cut. The cutting height is easily adjusted using a single lever, offering a versatile range from 14mm for a close trim up to 62mm, suiting most conditions through the mowing season.
The spacious 42-litre fabric grass catcher supports efficient grass collection, minimising trips to the compost bin. For those preferring a neater finish and improved lawn health, a mulching feature is also included — finely chopping clippings to return nutrients to the grass.
Designed for Hassle-Free Operation
Weighing 23kg, the Masport 150 ST SP remains easy to manoeuvre but substantial enough for a consistent finish, even on slightly uneven ground. Folding handlebars make the machine straightforward to store in sheds or garages.
Suitable Users and Lawn Sizes
This walk-behind mower is best suited to domestic users maintaining small to medium lawns — typically up to around 300m² (~three tennis courts). It is ideal for those seeking a straightforward, easy-start petrol lawn mower without complex settings or electronics, but who still need the convenience of a self-propelled drive, grass collection, and mulching options.
