Professional Performance for Demanding Use
The Ariens ZENITH 52 is engineered for daily professional and local authority use, delivering the pinnacle of performance, durability, and comfort. This machine is the choice for mowing professionals who require unwavering reliability. At its heart is a Kawasaki professional FX730V V-Twin engine, boasting a 726 cm³ displacement and a double air filter, ensuring consistent power for the toughest conditions.
Equipped with a wide 132 cm (52″) professional cutting deck, the ZENITH 52 is designed to cover large areas efficiently. It operates as a side-discharge mower as standard, but can be converted for mulching with an optional Mulchkit. This mower is perfectly suited for contractors, local councils, and owners of large estates who need a machine that can handle extensive and frequent use on areas including flat, undulating, and hilly terrain up to 15°.
Engineered for Durability and a Superior Cut
The foundation of the ZENITH 52 is its industry-leading, fully welded tubular steel frame. Constructed with automotive bending technology to minimise weld seams, this design provides unrivalled strength and stability to carry the machine’s loads. The cutting deck itself is a formidable 10-gauge fabricated steel ENVY™ deck, featuring improved airflow, an enlarged discharge, and blade spindles made from forged aluminium for cooler running and greater impact resistance. A 4-point suspension ensures the deck remains permanently fixed and parallel for a perfect cut every time.
Ariens’ automatic Constant Belt Tension (CBT) system maintains consistent tension on the mower deck belt, extending its service life, compensating for wear, and preventing slippage to guarantee a high-quality cutting pattern consistently.
Operator Comfort and Safety
For those who spend long hours on the machine, comfort is paramount. The ZENITH 52 excels with its fully adjustable comfort seat, which features hydro-pneumatic suspension that can be precisely adjusted to the driver’s body weight. This, combined with front caster fork suspension, adjustable armrests, and a high backrest with lumbar support, significantly reduces operator fatigue by absorbing shocks and vibrations. Safety is also a key feature, with a Roll-Over Protection System (ROPS) and safety belt fitted as standard. The ROPS is foldable and ergonomically tilted to prevent interference during operation.
Versatility and Optional Accessories
The ZENITH 52 is a versatile platform that can be enhanced with a range of optional accessories to meet specific needs. These include a Road homologation lighting kit for use on public roads, a striping kit for a pristine lawn finish, and a trailer hitch kit to tow various attachments. Other available enhancements are an operator controlled chute baffle, LED headlight kits, and a protective zero-turn cover. For ultimate durability, puncture-proof “TWEELS” kits and semi-pneumatic front tyre kits are also available.
