2025 STIHL Zero-turn mowers RZ 972i

This top-of-the-line professional zero-turn mower has a Vanguard® EFI engine and 72? deck.

The STIHL RZ 972i is built for hard work and operator comfort featuring an extra-wide, 72? deck and four-wheel innovative suspension system with mowing deck height compensation that create a smooth, stable ride. The Vanguard® Electronic Fuel Injection (EFI) engine with Oil Guard™ provides fuel efficiency and extends maintenance intervals. Built with heavy-duty, commercial grade materials and components, this mower is made to take on tough jobs.

Features may include:

  • Vanguard® Oil Guard™ System - Vanguard® Oil Guard™ System features a separate oil tank, transferring cool oil to the engine—helping oil last longer, increasing working times, and allowing for less maintenance.
  • Commercial-Grade Hydro-Gear® ZT-5400 Transaxles Include 9" Cooling Fans - Hydro-Gear® ZT-5400 transaxles offer a top forward ground speed of twelve mph and a top reverse speed of five mph, as well as nine inch cooling fans to prevent overheating.
  • Heavy-Duty 10" Cast Iron Greaseable Mower Deck Spindles with Taper Lock Pulleys - The STIHL RZ 900 Series features taper lock spindle pulleys to ensure perfect belt alignment and the tightest fit between the pulley and spindle to ensure a long service life.
  • Premium Suspension Seat - The STIHL RZ 900 Series features a premium suspension seat with adjustable backrest, adjustable lumbar support, and adjustable armrests.
  • Large Fuel Capacity - With a fuel gauge that is visible from the operator's seat, not only can users monitor fuel level and experience fuel coverage for large jobs, but the wide opening also makes fueling easy.
  • Four-Wheel Suspension System with Independent Front Suspension and Rear Shock Absorbers - Adjustable to suit your yard’s terrain, the rear suspension uses shock absorbers to help stabilize the machine for a consistent cutting height and a smooth, comfortable ride.
  • Independent Front Suspension with Mower Deck Height Compensation - Independent front suspension features two control arms that connect to shock absorbers, designed to ensure wheels remain perpendicular to the ground throughout the range of travel.
  • Swingarm Rear Suspension with Shock Absorbers - The adjustable rear suspension with shock absorbers are designed to help provide performance and comfort while mowing uneven surfaces.
