Ariens SUMMIT PRO: The New Standard in Professional Zero-Turn Mowing

Built for Professionals, Designed for Performance

In professional lawn care, reliability isn’t optional. Downtime means lost contracts, lost hours, and lost revenue. That’s why the new Ariens SUMMIT PRO series was engineered for one purpose: to keep professionals cutting at full capacity, season after season. With proven performance in the United States, this fleet leader is now coming to Europe for the 2026 mowing season.

The SUMMIT PRO delivers exactly what contractors & municipalities demand: maximum durability, a consistent premium cut, low downtime, and extended service life. Backed by premium Kawasaki engines, robust Parker transmissions, and Ariens’ signature zero-turn engineering, the SUMMIT PRO represents a decisive leap forward in the professional mowing segment.

A Model for Every Job

The Ariens SUMMIT PRO range offers five models to fit different site demands:

SUMMIT PRO 300 (26 hp) – available in three cutting widths (122 cm, 132 cm, 152 cm) for flexible use in both compact & mid-scale applications.
SUMMIT PRO 500 (27 hp) – available with 152 cm or 183 cm decks for maximum output on the largest areas.

Even the smallest model, the SUMMIT PRO 348, delivers an impressive mowing capacity of up to 17,800 m² per hour at 14.5 km/h. At the other end of the scale, the SUMMIT PRO 572 with its 183 cm cutting width achieves a staggering 29,500 m² per hour at 16 km/h – professional-scale efficiency redefined.

Strength in Every Detail

Robust Design

At the heart of the SUMMIT PRO is the new ENVY PRO cutting deck, made from 4.6 mm thick steel for extreme durability. Its deep profile ensures superior grass discharge & makes it ideal for optional mulching kits.

A fully welded one-piece tubular frame provides strength where it matters most. Large square tubing absorbs torsion & shock over years of tough, daily service.

High-Performance Spindles

Cold-forged aluminium spindles with sealed double ball bearings resist vibration & prevent dirt or moisture ingress. The result: longer service life, lower downtime, and consistent cut quality.

Kawasaki FX Engines

Professional-grade Kawasaki FX V-Twin engines with 852 cm³ displacement, dual air filters, and high-performance cooling ensure reliable full power under the most demanding workloads.

Productivity That Lasts All Day

A 48-litre fuel tank powers through entire working days without interruption. Parker hydrostats guarantee precise control:

HTJ hydrostats (SUMMIT PRO 300) – 17 km/h max speed, designed for heavy-duty reliability.
HTG hydrostats (SUMMIT PRO 500) – up to 24 km/h with gerotor motors, transferring up to 10% more power directly to the blades.

The result is smooth manoeuvrability, fewer service requirements, and higher operational efficiency.

Operator Comfort, Redefined

Professional mowing isn’t only about performance – it’s about endurance. The Ariens Air-Ride seat (standard on the SUMMIT PRO 500) ensures operators stay comfortable throughout long shifts. Adjustable air suspension, vibration isolators, armrests, lumbar support, and extra-thick padding make long days productive rather than punishing.

Front wheels are semi-pneumatic, meaning puncture-proof and maintenance-free. Large rear drive wheels (24” on PRO 300, 26” on PRO 500) add traction & stability across varied terrain.

Warranty & Planned Costs

The SUMMIT PRO is backed by one of the strongest warranties in the industry:

SUMMIT PRO 300 – 5 years or 1,250 hours
SUMMIT PRO 500 – 5 years or 1,500 hours

For the first two years, there are no hour limits. Predictable costs, long service intervals, and reliable support make SUMMIT PRO a smart investment.

The Next Era of Professional Zero-Turns

The Ariens SUMMIT PRO series combines maximum performance, operator comfort, and industry-leading reliability. Built for contractors, municipalities & large-scale operators, it’s designed to dominate demanding mowing schedules without compromise.
