Kohler XT800-3048 173cc Engine – 3-5/32in Shaft

Description

The Kohler XT800-3048 vertical shaft engine solves wide-area walk-behind repower challenges through high-displacement torque and an extended 3-5/32-inch drive shaft. Commercial wide-cut walk-behind mowers operating under continuous heavy turf cutting suffer shaft bending when fitted with lighter crankshafts. This 173cc engine incorporates an extended 3-5/32-inch vertical shaft, splash lubrication, and an advanced overhead valve cylinder layout that keeps head temperatures stable under heavy cutting decks.

An oversized cast-iron cylinder sleeve protects internal tolerances against bore wear, keeping oil consumption low across hundreds of operating hours. The 3-5/32-inch vertical shaft handles stacked transmission pulleys and commercial blade adapters without crankshaft deflection. The commercial-grade carburetor meters fuel with precision across varying load demands, preventing engine hesitation when mowing decks encounter thick, wet turf patches.

Engine Architecture of Kohler XT800-3048

• 173cc Commercial OHV Powerplant: Generates 8.00 gross torque ft-lbs to power wide-cut commercial walk-behind decks.
• 3-5/32-Inch Extended Vertical PTO Shaft: Matches stacked transmission drive pulleys and commercial blade adapters.
• Cast-Iron Cylinder Bore Liner: Resists bore wear from abrasive dirt, extending engine life in severe commercial service.
• Smart-Choke Automatic Choking System: Senses engine heat to meter startup fuel without choke levers or primer bulbs.
• Dual-Element Commercial Air Cleaner: Traps fine dust particles across two media layers to preserve cylinder wall compression.
• Mechanical Flywheel Brake System: Stops blade rotation within 3 seconds of safety bail release for crew protection.

Commercial Utility Stamina & Lifespan

Engineered for continuous commercial operation where equipment failure halts company revenue, this platform delivers reliable mechanical output.

• A rigid aluminum crankcase casting and cast-iron cylinder liner maintain shaft alignment under severe belt drive tension.
• High combustion efficiency lowers fuel burn per mowing shift, cutting daily operating expenses across commercial fleets.
• Landscape maintenance contractors and estate groundskeepers gain dependable power for high-hour mowing equipment.

Chassis Integration & Industrial Fitment

Weighing 32 pounds dry with an industry-standard vertical base pattern and 3-5/32-inch shaft, this unit drops directly onto commercial walk-behind mowers, wide-area turf equipment, and lawn vacuums without deck drilling.
