- Industry-leading fully welded tubular steel frame for maximum durability and stability.

The Ariens APEX 52R is engineered for professionals and service providers who demand high performance and reliability. Combining top-tier components with an exceptional price-performance ratio, this zero-turn mower is built for frequent, intensive use on large areas.
At its heart is the first-class Kawasaki FR691 V-Twin engine, delivering consistent power to the commercial-grade Hydro-Gear® ZT-3100 transaxles. The ‘R’ in its name signifies its key feature: a rear-discharge cutting deck. This design efficiently ejects grass clippings between the rear wheels, preventing them from being thrown onto paths, driveways, or into flower beds, ensuring a tidy finish.
Professional-Grade Construction
Durability is paramount in the APEX 52R’s design. The machine is built around an industry-leading, fully welded tubular steel frame, which provides a robust skeleton capable of withstanding years of shocks and vibrations without the weak points found in bolted frames. The 132 cm (52″) ENVY™ mower deck is fabricated from 10-gauge steel and is 14 cm (5.5″) deep, featuring improved airflow and an enlarged discharge for a perfect cut, even on grass that is lying down. This advanced deck is suspended at four points for stability and parallelism, and features blade spindles made of forged aluminium, which run cooler and are more resistant to impact than cast alternatives.
Operator Comfort and Precision Control
Long mowing sessions are made more comfortable thanks to the APEX 52R’s focus on ergonomics. It features a high-back plush seat with padded armrests and an adjustable operator position. The new ergonomic steering levers fit perfectly in the hand, providing effortless control and manoeuvrability. Raising and lowering the heavy-duty deck is made simple with the foot-operated, spring-assisted deck lift system. A simple metal plug allows the operator to select one of 15 cutting heights, ranging from 3.8 cm to 12.7 cm.
Designed for Efficiency and Easy Maintenance
The APEX 52R is ideal for a variety of demanding environments, including large estates, leisure facilities, and municipal grounds. It performs exceptionally well on flat, undulating, and even hilly terrain. Maintenance is streamlined with easy top-down access to the mowing deck for cleaning. Furthermore, the automatic Constant Belt Tension (CBT) technology not only ensures a consistent cutting pattern by preventing belt slippage but also simplifies belt changes, reducing downtime.
