The Cobra AirMow 51B: More Than Just a Hover Mower
The Cobra AirMow 51B represents a significant advancement in hover mower technology, blending powerful performance with user-friendly design. Cobra has thoughtfully expanded its AirMow range with this mid-tier model, which is powered by a robust Briggs & Stratton engine. This machine is engineered to make lawn maintenance, especially on slopes and uneven ground, a considerably less arduous task.

Understanding the Hover Mower Principle
At the heart of the AirMow 51B's operation is its under-deck impeller. This component generates a substantial downward force of air, creating an air cushion between the mower deck and the ground. This ingenious system allows the mower to glide effortlessly across the grass, minimising the physical effort required from the operator. This makes tackling large areas much quicker and more manageable. The freedom afforded by a petrol-powered machine is undeniable, and the AirMow 51B capitalises on this, offering excellent manoeuvrability, even on grassy slopes of up to a 45-degree angle.
Power and Performance: The Briggs & Stratton Advantage
Powering the Cobra AirMow 51B is a highly capable Briggs & Stratton 575EX Series engine. This engine is renowned for its smooth operation, best-in-class torque-to-weight ratio, reduced vibration, and quieter performance compared to many alternatives. Key to its user-friendliness is the ReadyStart technology. This feature simplifies the starting process considerably, eliminating the need for manual priming of the engine. Furthermore, the integration of OHV (Overhead Valve) technology ensures optimised engine performance, leading to a longer engine lifespan and improved fuel economy. This means more mowing time and less downtime or excessive fuel consumption.
Design and Durability: The ABS Deck
With a generous 51cm (20-inch) cutting width, the Cobra AirMow 51B is designed to cover ground efficiently. The mower features an exceptionally strong yet lightweight deck, manufactured from ABS injection-molded material. This choice of material is not merely for aesthetics; it significantly enhances manoeuvrability and provides superior control, particularly when operating on slopes and banks. The compact footprint of the Cobra AirMow contributes to its ease of operation in various garden sizes. Moreover, its solid, well-constructed design instils confidence, allowing users to tackle demanding conditions without concern for the mower's resilience.

The Game-Changer: The 3-in-1 Wheel Kit
One of the standout features of the Cobra AirMow 51B, and a direct answer to the question of its wheel configuration, is the inclusion of a 3-in-1 wheel kit system as standard. This innovative addition dramatically enhances the versatility of the hover mower. When the wheels are engaged, the AirMow 51B can be easily pushed over difficult and uneven terrain. This is particularly useful for transporting the mower to and from the mowing area or for navigating areas where hovering might be impractical or undesirable. If the wheels are not required for the task at hand, they can be effortlessly lifted and clicked securely into place, allowing the mower to revert to its traditional hover mode. This dual functionality makes the AirMow 51B adaptable to a wider range of user preferences and garden types.
How to Use the Wheel Kit:
Using the wheel kit is designed to be intuitive:
- Engaging Wheels: To use the wheels for pushing, simply lower them into the operational position. They will typically click into place, indicating they are securely fitted.
- Disengaging Wheels: When you wish to revert to hover mode, lift the wheels. They are designed to retract or fold upwards and secure themselves out of the way, often with a simple locking mechanism.
Comparing Hover Mowers with Wheels
The addition of a wheel kit to a hover mower like the Cobra AirMow 51B offers several advantages over traditional hover mowers:
| Feature | Hover Mower (No Wheels) | Cobra AirMow 51B (with Wheels) |
|---|---|---|
| Manoeuvrability on Flat Ground | Excellent (glides effortlessly) | Excellent (hovers) |
| Manoeuvrability on Slopes (up to 45°) | Excellent (air cushion provides stability) | Excellent (hovers) |
| Traction on Uneven/Wet Terrain | Limited (relies solely on air cushion) | Good (wheels provide physical grip) |
| Ease of Transport/Manoeuvring Off Grass | Requires lifting or sliding | Easy to push like a conventional mower |
| Versatility | Primarily for smooth, grassy surfaces | Suitable for smooth surfaces and easier on uneven ground |
| Storage | Compact | Compact (wheels can be retracted) |
