Made for regular mowing and service providers

Made for service providers who mow frequently. Top components in the engine, drive and cutter deck combined with an excellent price-performance ratio.

With its first-class Kawasaki FR691 V-Twin engine, its highly stable frame and its professional cutting deck with a cutting width of 132 cm, it is ideal for commercial use.

Features & Benefits

Curved tubular steel frame

The frame, made entirely of tubular steel, forms the skeleton of the mower. It bears the entire load of the machine for many years and must be able to cope with shocks and vibrations over the long term. State-of-the-art bending technology avoids weak points due to welded joints.

Professional mowing deck

The mowing deck is the most heavily loaded component of a mower. Stability is particularly important here. The APEX has a 14 cm deep, fully welded mower deck made of 3.2 mm thick sheet steel with double spindle supports, 12.7 mm steel edge, enclosed anti-scalp wheels, all-steel pulleys, welded 4-point suspension and high-quality blade spindles made of forged aluminium. Everything about it is designed for a long service life.

Automatic belt tensioner system

The automatic CBT (Constant Belt Tension) technology keeps the belt tension of the mower deck constant at all times. This increases the service life of the belt, compensates for wear and prevents belt slippage for a consistently high-quality cutting pattern.

Mower deck lifting by foot pedal

The solid cutting deck is raised conveniently and effortlessly using a foot pedal. To select one of the 15 cutting heights from 3.8 - 12.7 cm, a metal plug is inserted into the respective recess in the display.

Easy access to the mowing deck

The mowing deck is easy to access from above for cleaning and maintenance. Thanks to CBT technology, changing the belt takes just a few minutes. Simply slacken the tensioning pulleys, thread in the belt, tension the tensioning pulleys again - done.

Padded seat and armrests

The soft, adjustable seat with high backrest is equipped with padded armrests for greater comfort even during long periods of mowing. Coil spring damping absorbs shocks on uneven surfaces.

Customer reviews

The Apex was purchased for one particularly challenging site. A mix of informal lawns, park lands, meadow areas and access tracks. The site regularly floods 3 to 4 times a year which can limit the number of times we can mow so hence has to handle a wide variety of ground and grass conditions. The Apex has exceeded all expectations and greatly increased efficiently. Having been so impressed with the cut quality we now use the zero turn on some of our more larger formal lawns which previously mowed using walk behind roller mowers.
– Graeme Mann, Berkshire Garden Service Ltd
We use our Ariens APEX 48 zero turn mower on village greens and commercial properties that are cut on a weekly basis. It has a fantastic quality of cut, it’s easy to manoeuvre into tight spaces and is powered by a strong and dependable Kawasaki engine.
– Jimmy the Mower, Ditton Services Ground Maintenance
I needed a mower that was light, manoeuvrable and solid. The grass on my property is anything but tight and straight. There are also quite a few hidden stones, or branches of trees that get in the way. With the APEX 52, I don’t have to worry about it, this zero-turn is so strong and robust. It’s a pleasure to drive and it’s always satisfying to look back afterwards and see the quality of the cut.
– Corne Smeets, private user
We carry out many grounds’ maintenance contracts including a site with 6 football pitches on. We have found that the APEX is brilliant for it, it’s fast and leaves a great finish. A great machine!

Peter Williams, private user

I wish my dad had an ARIENS zero turn mower. Peter Williams kindly reviews his new Ariens APEX 52 inch zero-turn mower after purchasing it in early spring. He’s been using it frequently since he purchased it from his local dealer, Hertfordshire Garden Machinery. “It’s a fantastic mower, with a great cutting width. I have about an acre and a half of grassland and I purchased this machine with a view of maintaining my lawn and grounds as pain free and easy as possible. Its manoeuvrability is fantastic and goes right around trees, you hardly need to strim afterwards which is a big bonus. [..] Out of 10, I’d give it 9.9. Not much wrong with this machine, great value for money and I’d highly recommend it”.


Service providers

Time is money for a service provider. Modern zero-turn mowers are therefore particularly popular with them. Time savings of up to 40 % come into their own here. Daily changing job sites and high annual operating times place demands on the material. The Ariens APEX and ARROW zero-turn models bring momentum and speed to the daily work of lawn care service providers.

Leisure Facilities

Camping sites and playgrounds are usually very winding. A zero-turn mower is ideal here and fully in its element. You can steer around obstacles with absolute maneuverability and precision. You can drive around a tree in one go. A zero-turn mower makes your work much easier.

Janitorial services

The constantly changing activities of a janitor service are part of daily routine. Regular lawn mowing is often perceived as a chore and is particularly time-consuming. With a zero-turn mower, you'll be done faster. You can save up to 40% time compared to a conventional lawn tractor. The Ariens IKON is made for private gardens of any size or even semi-professional applications. For smaller janitor services, it is the ideal machine for mowing green spaces quickly and maneuverably.

Municipalities & building yards

User comfort for long mowing jobs in public spaces. Efficient work that is fun and enjoyable. The Ariens models ZENITH, ZENITH E, ARROW and ARROW E zero-turn mowers are made for long and frequent mowing intervals on large areas. Perfect cut and durability come as standard. Suspended wheel forks, optimum seating comfort or ergonomic, upright driving position on the ARROW models protect the user and increase their well-being.
