2026 STIHL Zero-Turn Mowers RZ 960i

The Stihl RZ 960I I/D is a top-tier, commercial-class zero-turn mower built for heavy-duty landscaping, acreage management, and professional turf care, combining rugged construction with high-performance power and precise control. At its heart is a high-displacement industrial diesel engine in the 900–1000 cc class delivering robust torque and fuel-efficient output, typically around 30–32 hp, with a vertical shaft, liquid-cooling, direct injection, and a heavy-duty air filtration system for long life in dusty or challenging conditions. Power flows through dual commercial hydrostatic transmissions offering smooth, infinitely variable forward and reverse speeds, true zero-turn agility via independent control levers, and excellent traction on slopes and uneven ground. The mower’s fabricated steel cutting deck is a broad 72 inch cutting width designed for large swaths of turf, with reinforced side skirts, anti-scalp rollers, heavy-duty sealed spindles, and a wide range of cutting heights — typically adjustable from about 1.5 to 5 inches via a foot-lift system with a clear height gauge.

Built on a fully welded steel frame with integrated roll-over protection structure (ROPS), the RZ 960I I/D rides on oversized, turf-friendly rear drive tires and smooth caster front wheels, providing stability and flotation while minimizing turf damage. The operator station is designed for full-day comfort, with a high-back, suspension-style seat, ergonomic lap bars, easily reachable throttle, choke, and PTO controls, and a large, anti-slip foot platform. A generous fuel tank capacity in the 12–14 gallon range supports extended mowing sessions without frequent refills. Additional professional features include heavy-duty front bumpers, quick-access service points, grease fittings on all critical pivot points, and durable belt and pulley guards, all engineered to reduce downtime and maintenance. Altogether, the Stihl RZ 960I I/D delivers diesel-powered strength, commercial-grade durability, and precise maneuverability for the most demanding mowing applications.
