Key Features & Benefits
1. Powerful 173cc Cobra DG600 Engine
The Cobra DG600 OHV engine delivers high torque, making it effective for cutting dense or damp grass without losing efficiency. Its overhead valve (OHV) design improves fuel efficiency, reduces emissions, and lowers noise levels compared to older side-valve engines.
2. Rear Roller for a Classic Striped Finish
A full-width steel rear roller allows users to create a traditional striped lawn. The roller also provides additional stability when mowing along lawn edges, preventing scalping.
3. 4-Speed Self-Propelled Drive
Unlike standard push mowers, the RM514SPC features a 4-speed transmission, allowing users to adjust the pace depending on the lawn conditions.
4. 51cm Cutting Width & Adjustable Cutting Heights
The wide 51cm (20″) cutting deck ensures efficient mowing, reducing the time needed for larger lawns. With six height settings (17mm to 75mm), the mower can handle both short ornamental lawns and longer grass.
5. Large 70-Litre Grass Collector
The fabric grass collector is designed to maximize airflow, ensuring efficient grass collection while reducing the frequency of emptying.
6. Durable Steel Deck
The heavy-duty steel chassis ensures the mower can withstand regular use, making it a long-lasting investment for both homeowners and professional gardeners.

The Cobra RM514SPC is designed for those seeking power, precision, and ease of use. The rear roller ensures a clean, professional striped finish, while the self-propelled function makes mowing effortless, even on uneven terrain or slopes.
