Superior Rear-Discharge Mower for Professional Results
The Ariens APEX 48R is engineered for service providers and property owners who mow frequently and demand top-tier components and performance. The ‘R’ signifies its rear-discharge capability, where clippings are efficiently ejected between the wheels for a clean finish without throwing debris onto paths or flowerbeds. Powered by a first-class Kawasaki FR691 V-Twin engine and built upon a highly stable frame, this semi-professional zero-turn mower is ideal for commercial use on medium-to-large sized areas, including flat, undulating, and hilly terrain up to 15°.
Engineered for Durability
At the core of the APEX 48R is an industry-leading, fully welded tubular steel frame. This advanced design avoids the weak points of bolted frames, providing a robust skeleton that can withstand shocks and vibrations for years of service. The professional 122 cm (48″) ENVY™ mower deck is fabricated from heavy-duty 3.6mm (10-gauge) steel and features improved airflow and an enlarged discharge for a perfect cut, even on dense grass. Durability is further enhanced by forged aluminium blade spindles, which run cooler and are more resistant to impact than cast alternatives. The automatic Constant Belt Tension (CBT) system maintains optimal belt tension, increasing belt life and ensuring a consistent, high-quality cut.
Operator Comfort and Control
Long mowing sessions are made more comfortable with the APEX series’ focus on ergonomics. The machine features new ergonomic steering levers that fit perfectly in hand for effortless control. A thickly padded, high-back premium seat with adjustable armrests ensures maximum comfort and support. The deck height is easily adjusted via a foot-operated, spring-assisted lift system, allowing the operator to select one of 15 cutting heights (from 3.8 cm to 12.7 cm) with a simple metal plug. Maintenance is also simplified, with an easy-access panel on the mowing deck for cleaning and belt changes.
Optional Accessories for Enhanced Versatility
The Ariens APEX 48R can be customised to meet specific needs with a wide range of optional accessories. Enhance its utility with a trailer hitch kit, improve safety with a foldable ROPS (Rollover Protection Structure), or boost comfort with a full suspension seat kit and suspension forks kit. Other available upgrades include LED headlight kits for mowing in low light, a protective zero-turn cover, and puncture-proof tyre solutions like the “TWEELS” kit and 13″ semi-pneumatic front tyre kit. For improved traction on slopes, an aggressive tread pattern rear tyre kit is also available.

Frequently Asked Questions
Frequently Asked Questions
Who is the Ariens APEX 48R best suited for?
The Ariens APEX 48R is designed for semi-professional and commercial users like service providers, janitorial services, and municipalities who mow frequently and require durability and efficiency. It is ideal for maintaining medium to large-sized areas.
What is the benefit of a rear-discharge deck?
The rear-discharge design ejects clippings neatly between the rear wheels. This prevents grass from being thrown onto paths, flowerbeds, or patios, resulting in a cleaner finish and less clean-up work. It also handles taller grass more effectively than a dedicated mulching deck.
Can the APEX 48R be used on slopes?
Yes, the APEX 48R is suitable for hilly and undulating terrain. However, for operator safety, Ariens specifies not to exceed a 15° incline. The optional ROPS (Rollover Protection Structure) is highly recommended for enhanced safety when working on slopes.
What warranty is included with the APEX 48R?
The Ariens APEX 48R comes with a comprehensive limited warranty of 4 years or 500 hours, whichever comes first, providing excellent peace of mind for your investment.
What makes the frame and deck so durable?
The mower is built on a fully welded, curved tubular steel frame that avoids the weak points found in bolted frames. The ENVY™ cutter deck is fabricated from heavy-duty 10-gauge (3.6 mm) steel and features forged aluminium spindles, which are more resistant to impact and vibration than cast alternatives.
