Kawasaki FS730V-S09 24.0HP 726cc Engine – 1-1/8in Shaft, Electric Start

Description

Need to repower a stalled commercial zero-turn mower? The Kawasaki FS730V-S09 vertical shaft engine provides an exact drop-in replacement that eliminates costly deck modifications. Commercial landscape crews wear out stock utility motors through constant heavy mowing, resulting in scored cylinder walls and hard morning starts. This 726cc 24.0HP engine uses an overhead valve V-twin design and cast-iron cylinder sleeves to handle harsh commercial demands.

The 1-1/8-inch crankshaft handles drive belt tension on twin hydrostatic drives, while full-pressure lubrication protects moving components against premature wear. The heavy-duty 12V starter motor engages the flywheel ring gear with positive solenoid drive, turning the crankshaft without manual effort on cold mornings. The dual-element commercial air cleaner prevents pulverized grass chaff and field sand from eroding the intake valve seat, preserving engine compression year after year.

Core Mechanical Specifications of Kawasaki FS730V-S09

• 726cc 24.0HP Commercial Turf Engine: Supplies robust cutting torque to slice through dense overgrowth without engine stall.
• 1-1/8-Inch Keyed Output Shaft: Integrates with standard commercial blade adapters and ground-drive transmission systems.
• Full-Pressure Oil Lube with Spin-On Filter: Circulates pressurized oil to rod bearings and main journals during steep incline runs.
• Cast-Iron Cylinder Bore Protection: Preserves compression and limits oil burn during prolonged commercial cutting shifts.
• Heavy-Duty Commercial Air Filtration: Dual-element design protects carburetor and cylinder bore from fine lawn dust.

Mechanical Advantages for Commercial Fleets

Engineered to withstand daily field use, this vertical-shaft engine combines heavy torque displacement with operator-friendly starting.

• Heavy cast iron bore lining and hardened crankshaft journals prevent mechanical failure from blade shock.
• Overhead valve design cuts fuel expenditure per route while providing broad torque bands for commercial equipment.

Equipment Fitment & Repower Applications

With an overall dry weight of 85 pounds and a 1-1/8-inch vertical PTO shaft, this unit repowers commercial zero-turn mowers, stand-on turf units, and wide-area rotary mowers without frame drilling.

Factory Warranty Protection & Service Care

• Commercial equipment owners receive 3-Year limited factory warranty coverage on internal mechanical assemblies.
• Consumer property owners receive 3-Year standard factory warranty protection.

Change oil after the initial 20 operating hours, then service every 100 hours with SAE 30 or 10W-30 oil and a new filter. Inspect the air filter weekly, and set the spark plug gap at 0.030 inches.
