STIHL RZ 560 K 24 HP Kawasaki 60-Inch Commercial Zero-Turn Lawn Mower

Product Description The STIHL RZ 560 K Commercial Zero-Turn Lawn Mower combines professional Kawasaki engine power, a wide commercial-grade cutting deck, responsive hydrostatic drive, and an advanced suspension system for maintaining large residential, agricultural, institutional, and commercial properties. It is powered by a Kawasaki FT730V 726cc V-Twin gasoline engine rated at 24 HP. The engine uses an overhead-valve, air-cooled design with two cylinders, electronic spark ignition, pressurized lubrication, cast-iron cylinder liners, and a carburetor with a fuel shut-off solenoid. These features are designed to provide consistent power and dependable operation during extended mowing sessions. Kawasaki’s Vortical Air Filtration system uses centrifugal airflow and dual-element filtration to help separate grass, dust, and debris before they reach the engine. Large integrated clean-out ports provide access for inspection and cleaning, while the rotating metal grass screen helps reduce debris accumulation around the engine’s air-intake area. The engine produces immediate mechanical power for demanding mowing conditions, including thick grass, rapidly growing turf, open commercial grounds, and properties with moderate terrain changes. Actual productivity depends on grass height, moisture, terrain, cutting height, travel speed, blade condition, tire traction, and operator technique. The mower is equipped with a 60-inch commercial-grade fabricated cutting deck. Its wide cutting path allows the operator to cover more ground with each pass, improving productivity on large properties while remaining maneuverable around trees, pathways, buildings, fences, landscaped areas, and other obstacles. The deck uses three cutting blades to cover the full 60-inch mowing width. STIHL uses durable cutting components designed to produce a clean, consistent finish while handling the demands of frequent professional mowing. Blade condition, deck cleanliness, engine speed, and ground speed directly affect the final cutting result. Cutting height can be adjusted between approximately 1.5 and 5 inches. Thirteen cutting-height positions allow the operator to configure the mower for maintained lawns, taller turf, seasonal growth, dry summer conditions, and different customer preferences. A foot-operated deck-lift system allows the cutting deck to be raised and adjusted while the operator remains seated. The spring-assisted mechanism reduces the effort required to reposition the commercial deck and makes it easier to respond to changing mowing conditions. Grass clippings are discharged through a flexible rubber side-discharge chute. The flexible construction helps the chute move around obstacles more safely than a rigid metal chute while directing clippings away from the mower’s cutting path. The mower uses a commercial two-belt deck-drive system. Distributing the operating load between two belts reduces excessive belt flex and strain, allowing the belts to operate cooler and supporting longer service life under demanding mowing conditions. Routine belt inspection, tension checks, and replacement are still required according to the maintenance schedule. Three greaseable 5.25-inch aluminum mower-deck spindles support the cutting blades. Their serviceable design allows lubrication to be added during routine maintenance, helping protect the spindle bearings and extend component life. The RZ 560 K uses dual commercial-grade Hydro-Gear ZT-3400 hydrostatic transaxles. Independent control of the rear drive wheels gives the mower true zero-turn maneuverability, allowing it to rotate within its own footprint and navigate efficiently around landscaping, trees, corners, and other obstacles. Maximum forward travel speed is approximately 10 MPH, while maximum reverse speed is approximately 5 MPH. The operator controls direction and speed using dual lap bars. Pushing both controls forward moves the mower ahead, pulling them back reverses the mower, and moving them independently controls turning. The ZT-3400 transaxles include large cooling fans that help manage operating temperatures during extended use. Actual ground speed should be adjusted according to grass density, surface conditions, visibility, terrain, and desired cut quality rather than operating continuously at maximum speed. An advanced four-wheel suspension system helps improve comfort, stability, and cutting consistency over uneven surfaces. Independent front suspension uses upper and lower control arms connected to shock absorbers, helping the front wheels remain properly positioned as they move over changing terrain. The front suspension works with mower-deck height compensation to help maintain a more consistent cutting position as the wheels and suspension move. This reduces the amount of deck movement transferred from bumps and uneven ground. At the rear, an adjustable swingarm suspension system with shock absorbers helps absorb impacts and stabilize the mower. The complete suspension system is designed to provide a smoother ride during extended commercial mowing while supporting a more uniform finished cut. A deluxe high-back operator seat with armrests provides support during long mowing sessions. The open operator platform, accessible controls, integrated cup holders, and lap-bar steering layout are designed to keep essential functions within easy reach. The mower includes a dual-function digital hour meter that records operating time and mowing hours. This information helps owners and fleet managers schedule engine-oil changes, filter service, lubrication, blade inspection, belt checks, and other routine maintenance at the correct intervals. Two integrated USB-A ports provide up to 3.15 amps of charging power for compatible mobile devices. Cup holders provide storage for drinks, while the visible fuel gauge lets the operator monitor the remaining fuel level without leaving the seat. The flip-up floor pan provides convenient access to the top of the cutting deck for cleaning, inspection, belt checks, and routine maintenance. Removing accumulated grass from the deck area helps maintain airflow, reduce corrosion, and prevent excessive buildup around belts and pulleys. A folding Roll Over Protection System is installed to provide added operator protection when used correctly with the appropriate restraint system. Polyurethane blocks help reduce rattling, and the structure can be folded when additional clearance is required for storage or trailer transportation. The ROPS should remain in its recommended operating position whenever conditions allow. An integrated rear trailer hitch allows the mower to tow compatible lawn-care attachments within STIHL’s approved operating limits. Potential accessories may include utility carts, lawn sweepers, spreaders, aerators, and dethatchers. Towing capacity, slope limitations, and attachment compatibility should always be confirmed before use. The RZ 560 K weighs approximately 1,290 pounds without fuel. Its substantial commercial construction, wide stance, large rear tires, suspension system, and hydrostatic drivetrain provide a stable operating platform for professional mowing. Overall shipping or carton dimensions are approximately 91 inches long, 69 inches wide, and 48 inches high. Actual operating dimensions may differ according to ROPS position, discharge-chute position, tire configuration, and dealer preparation. Unlike the standard STIHL RZ 560, which uses a Briggs & Stratton engine, the RZ 560 K specifically uses the Kawasaki FT730V engine. Retailers should clearly identify the “K” model in the product title and specifications to avoid presenting engine information from the standard RZ 560 variant. Routine maintenance includes engine-oil and filter changes, air-filter inspection, spark-plug servicing, fuel-system care, deck cleaning, blade sharpening or replacement, belt inspection, spindle lubrication, tire-pressure checks, hydrostatic-system inspection, and suspension checks. Maintenance frequency should follow the STIHL mower manual and Kawasaki engine manual.
