Key Features and Performance

• Engine Power: The Briggs & Stratton EXi725 163cc engine is the heart of the Razor 21, providing ample power for challenging mowing tasks. Its Mow N’ Stow® feature ensures that it’s ready for action without the need for regular oil changes.

• Discharge Dilemma: Although marketed with a rear discharge capability, practical experience suggests this feature is limited. Grass tends to clump on one side, indicating that the mower excels more in mulching and bagging than in rear discharging.

• Storage and Maintenance: Its vertical storage capability is a game-changer, reducing its footprint and making blade maintenance more accessible.

Practical Insights and User Experience

During my use, the mower handled wet grass impressively, showcasing its deep deck design’s efficiency in preventing clogs and ensuring a clean cut. The bagging system, though asymmetrically vented, held up well, managing to capture wet grass without any hassle.

Fuel Efficiency and Maintenance

The fuel economy of the Ariens Razor 21 was remarkable. Despite extensive use on hilly terrain, the mower sipped fuel, making it economical for longer mowing sessions. Maintenance seems straightforward, with easy access to essential components like the air filter and spark plug.

Design and Build

The mower’s design, featuring a 14 gauge steel deck, is built for durability. Adjustments for height are intuitive, affecting both front and rear wheels simultaneously, which simplifies transitioning between different lawn areas.

Pros and Cons of the Ariens Razor 21 Self-Propelled Mower

Pros

• The Briggs & Stratton EXi725 163cc engine is a beast. It starts easily, runs smoothly, and has enough power to cut through tall, wet grass without bogging down. This kind of power makes mowing less of a chore and more of a breeze.
• The rear-wheel-drive and REFLEX Speed Control make navigating through uneven terrain and around obstacles feel effortless. It’s like the mower is doing half the work for you, especially on slopes.
• I love that I can switch between mulching and bagging depending on what my lawn needs. The bagging system, despite being vented on one side, holds a surprising amount of clippings, which is a huge plus.
• This mower sips fuel! Even after tackling my hilly and sizable yard, the fuel gauge barely moves. It’s economical and reduces the number of refills needed during a mow.
• The Mow N’ Stow feature is fantastic for saving space in my garage. Flipping it upright makes it easier to clean and maintain the blade too.

Cons

• The mower is marketed with rear discharge functionality, but it doesn’t live up to that promise. Clippings tend to clump on one side, which can be frustrating if you prefer discharging over mulching or bagging.
• While the self-propel feature is great, the mower can feel a bit heavy and awkward to turn, particularly on tighter corners or when you need to lift the front end for maneuvering.
• Adjusting the cutting height is straightforward, but for other settings or maintenance tasks, I find myself referring back to the manual. It’s not overly complicated, but it’s not as intuitive as I’d like.
• The bag fills unevenly due to the venting being on one side. While it does capture a lot of clippings, I have to shake the bag to distribute the contents and make full use of its capacity.
• While not the loudest, it’s not whisper-quiet either. I don’t mind the sound, but it’s something to consider if you prefer a quieter mowing experience.

Maintenance and Care for Ariens Razor 21

• Regular Maintenance Regularly checking the engine oil before use is crucial to ensure the smooth operation of your Ariens Razor 21. Changing the oil according to the manufacturer’s recommendations, or at least once every mowing season, helps maintain engine health. The air filter should be cleaned regularly to prevent dirt from affecting the engine’s performance, and replaced if it’s too dirty or damaged. The spark plug, an essential component for starting your mower, should be inspected annually or if you encounter starting difficulties, and replaced if found faulty. Keeping the mower clean by removing grass clippings and debris after each use prevents clogging and corrosion, extending the lifespan of the machine.
• Blade Maintenance The mower’s blade requires periodic inspection for signs of wear or damage. A sharp blade is key to achieving a clean and efficient cut, so sharpen the blade as needed and replace it if it becomes bent, cracked, or too worn out. Proper blade maintenance ensures optimal mowing performance and prevents unnecessary strain on the engine.
• Drive System Care For models with a drive belt, inspect it regularly for signs of wear or damage and replace it when necessary to maintain the self-propel function. Adjusting the self-propel feature ensures that the mower moves at a comfortable pace, enhancing the ease of mowing especially on varied terrain.
• Seasonal Care End-of-season maintenance is crucial for the longevity of your mower. Thoroughly clean the machine and either run the engine until the fuel tank is empty or use a fuel stabilizer to prevent the gas from deteriorating. Storing the mower in a clean, dry place protects it from the elements and preserves its condition. Before the mowing season begins, a comprehensive check of the oil, air filter, spark plug, and blade will prepare the mower for optimal performance.
• Electric Start Models If your Ariens Razor 21 features an electric start, regular battery maintenance is essential. Charge the battery before the start of the season and monitor its condition to ensure reliability and readiness for use.
• Specific to Ariens Razor 21 The REFLEX™ Speed Control system on the Ariens Razor 21 requires regular checks to ensure it matches your walking pace accurately, providing a comfortable mowing experience. If you utilize the vertical storage feature, inspect the mower upon returning it to the operating position to ensure everything is aligned and secure, maintaining the integrity of the machine.
