John Deere Q850M – QuikTrak™ Stand-On Mower

The John Deere Q850M QuikTrak™ Stand-On Mower is a high-performance commercial mower engineered for professional landscapers who demand speed, durability, and precision. Designed to maximize productivity in demanding mowing conditions, the Q850M combines powerful performance with exceptional maneuverability and operator comfort.

At its core, the Q850M is powered by a 27-hp (20.1-kW) Kawasaki FX850V V-twin gasoline engine, delivering strong and consistent power at 3,600 rpm. With a displacement of 852 cc, full-pressure lubrication, a heavy-duty air filtration system with safety element, and forced-air cooling with integrated clean-out ports and an oil cooler, the engine is built for long service life and reliable operation in tough environments.

The mower is available with 54-inch or 60-inch 7Iron™ PRO side-discharge mower decks, constructed from one-piece forged 7-gauge steel for superior strength and impact resistance. The deck delivers a clean, professional cut with a blade tip speed of approximately 18,000 fpm, while adjustable cutting heights ranging from 1.5 to 5 inches in 0.25-inch increments allow precise control across varying turf conditions. Front anti-scalp rollers further protect turf quality on uneven ground.

The Tuff Torq® TZT13 integrated hydrostatic transmission provides smooth, responsive control with infinite speed adjustment. The Q850M reaches mowing speeds of up to 10 mph (16.1 km/h) forward and 5 mph (8 km/h) in reverse, significantly increasing jobsite efficiency. Twin hand-controlled levers offer precise steering, while dynamic braking and an internal wet-disc parking brake ensure safe operation.

Designed for operator comfort and visibility, the stand-on platform allows quick on-and-off access, ideal for frequent stops. The mower is equipped with a comprehensive digital display panel, including an hour meter, fuel level, engine speed, system voltage, oil pressure warning, safety interlock indicators, diagnostic alerts, and operator-presence starting system.

Durability is reinforced by heavy-duty 22-inch drive wheels (pneumatic or optional Tweel®), flat-free caster wheels, and a robust frame capable of handling commercial workloads. A large 12-gallon (45.3-L) fuel tank supports extended mowing sessions with fewer refueling stops.

Backed by John Deere’s commercial warranty of 36 months or 1,200 hours (with no hour limitation during the first 24 months), the Q850M offers long-term confidence and reduced downtime for professionals.

In summary, the John Deere Q850M QuikTrak™ Stand-On Mower delivers exceptional power, speed, cutting quality, and durability, making it an ideal solution for commercial landscaping operations seeking maximum productivity and precision in a compact, stand-on design.
