ATCO LINER 18SH 46cm Self-Propelled Rear Roller Petrol Lawnmower

Powerful Honda Performance. Beautiful Traditional Stripes. Effortless Lawn Care.

Achieve that beautifully manicured lawn with the ATCO LINER 18SH, a powerful and versatile self-propelled petrol lawnmower combining Honda engine performance with the traditional striped finish that only a full-width rear roller can deliver.

Designed for homeowners who take pride in their lawns, the LINER 18SH brings together a robust steel cutting deck, a generous 46cm cutting width and a dependable 145cc Honda GCVx145 Autochoke engine. Whether you're maintaining a well-established lawn or tackling longer grass and uneven areas, this mower has the performance and features to make lawn care easier and more rewarding.

Powerful Honda 145cc Engine

At the heart of the LINER 18SH is the Honda GCVx145 four-stroke OHV engine. Delivering 2.75kW of power at 2,900rpm, this reliable and efficient engine provides excellent cutting performance with smooth, consistent operation.

Honda's Autochoke technology helps simplify starting, while the overhead valve design promotes efficient combustion, reduced emissions and dependable performance. With a generous 0.95-litre fuel tank, you can spend more time mowing and less time stopping to refuel.

Traditional Stripes with a Full-Width Rear Roller

For that unmistakable professional-looking striped finish, the LINER 18SH features a substantial full-width rear roller. As the mower travels across the lawn, the roller gently presses the grass in alternating directions, creating the attractive light and dark stripes associated with beautifully maintained lawns.

The rear roller also provides additional stability and allows you to mow neatly along lawn edges, helping achieve a smart, consistent finish around borders and pathways.

Self-Propelled Convenience

Forget the effort of pushing a heavy mower around the garden. The LINER 18SH features a self-propelled rear-roller drive system, taking much of the hard work out of mowing.

Travelling at approximately 4.1km/h, it provides a comfortable, consistent mowing pace, making it particularly useful when maintaining larger lawns, inclines and more demanding areas of grass.

Excellent Cutting Performance and Adjustable Heights

With its generous 46cm cutting width, the LINER 18SH covers more ground with every pass, helping reduce mowing time while delivering an attractive, even finish.

The centralised single-lever cutting-height adjustment provides five positions between 20mm and 70mm, allowing you to adapt the cutting height to suit the lawn, season and growing conditions.

A front anti-scalp skid plate helps protect the turf when manoeuvring, particularly over uneven ground, while the robust steel cutting deck provides durability for regular garden use.

Generous 55-Litre Grass Collection

The large 55-litre grass collector means fewer interruptions to empty clippings, making it easier to complete the job efficiently. Its handy grassbag-full indicator lets you know when the collector needs emptying, helping maintain effective collection throughout the mowing session.

The hybrid collector combines a durable construction with convenient handling and collapsible storage.

Comfortable Handling and Convenient Storage

ATCO has designed the LINER 18SH with user comfort in mind. Its ergonomic soft-grip handlebars feature two height adjustment settings, helping you find a comfortable working position.

When mowing is finished, the handlebars can be folded down to reduce the space required for storage. The integrated washing link also makes cleaning the underside of the cutting deck easier – simply connect a garden hose to help remove accumulated grass and debris.

A Quality Petrol Roller Mower from ATCO

Combining the proven performance of Honda engineering with ATCO's traditional lawn-care expertise, the LINER 18SH is an excellent choice for homeowners looking for a capable, self-propelled petrol mower with the added benefit of a traditional striped finish.

With its powerful Honda engine, substantial collection capacity, convenient features and full-width rear roller, it offers an excellent balance of performance, comfort and practicality.
