Powerful Briggs & Stratton InStart Engine

At the core of the COBRA RM433SPBI lies the Briggs & Stratton 575IS Series engine, designed for dependable, smooth operation. The 150cc engine provides exceptional torque and efficiency, delivering consistent cutting performance even in challenging conditions.

Effortless Mowing with Three-Speed Self-Propelled Drive

The COBRA RM433SPBI features a self-propelled drive with three selectable speeds, ensuring total control over your mowing pace. The available speeds range from 3.1km/h to 4.2km/h, allowing you to adjust easily to suit your terrain and comfort. This feature eliminates the strain of pushing the mower, particularly on slopes or larger gardens. The smooth, steady drive enhances user comfort, making mowing effortless and enjoyable while maintaining consistent cutting precision.

Classic Striped Finish with Rear Roller Design

For those who take pride in a beautifully striped lawn, the COBRA RM433SPBI includes a heavy steel rear roller that produces a professional-quality finish. The roller flattens grass blades in alternating directions, creating a classic, defined stripe effect that enhances the lawn’s overall appearance. It also stabilises the mower for precise edge cutting along flowerbeds and borders without tipping. This design ensures every pass produces smooth, elegant stripes for a truly refined garden look.

Flexible Cutting Heights for Every Lawn

The mower offers six adjustable cutting heights, ranging from 17mm to 75mm, giving you complete flexibility for all seasons and grass types. Adjustments are made quickly using a single central lever, allowing you to fine-tune your desired cut effortlessly. Lower settings provide a manicured, close finish, while higher settings handle thicker or overgrown grass with ease. This adaptability ensures that your lawn maintains the perfect look throughout the year.

Efficient Grass Collection and Tidy Results

The COBRA RM433SPBI is equipped with a 50-litre grass collection bag made from high-quality, durable fabric. The bag design promotes excellent airflow, compacting grass efficiently and reducing the need for frequent emptying. A grass bag full indicator conveniently alerts you when it’s time to empty, ensuring continuous, uninterrupted mowing. This collection system leaves your lawn neat and free from clippings, saving time while delivering a pristine finish.

Durable Steel Deck and Practical Design

The steel deck construction of the COBRA RM433SPBI ensures long-lasting durability, even under demanding use. Its folding cam-lock handles make storage and transport simple, while the mower’s lightweight 32kg frame offers excellent manoeuvrability without compromising stability.
