Fuel Type
25 Vertical V-Twin Air Gasoline Retired

Professional Grade Design.

Professional grade engineering for the consumer. Cool-running OHV design and tough cast-iron cylinder bore provides better fuel efficiency, more torque per unit of displacement and means your engine will last longer in harsh mowing conditions - so you can keep your mower longer and avoid costly trips to the repair shop.

Durable, Long Life Design.

Hardened crankshaft bearings are built extra tough for superior strength and added protection under high-load, heavy-debris mowing conditions. The large capacity, professional oil, air and fuel filters provide even better performance under tough conditions for longer engine life.

High Power Performance.

Consistent-Cut™ technology delivers more consistent power to your mower deck in extreme load conditions, maximizing cutting, bagging, and mulching performance. So you can rest assured knowing there will be less clumping and missed areas.

Comfortable Operation.

Tough on grass, easy on you. V-Twin design provides smooth operation and the acoustically dampened air induction system reduces noise for quieter operation. This engine also features a flip-up air cleaner cover that allows for quick inspection and change

Reliable Starting.

High-torque inertia drive starter ensures quick, reliable starting in all conditions.

Increased Efficiency.

Overhead valve design makes KOHLER® engine more fuel efficient and provides more power per displacement while emitting fewer harmful exhaust gasses.

1 Power (hp) and Torque (lbs ft) specifications for Kohler general purpose engines are rated pursuant to Society of Automotive Engineers (SAE) J1940 based on gross output testing performed according to SAE J1995 without the air cleaner and muffler. Actual engine power and torque are lower and affected by accessories (air cleaner, exhaust, charging, cooling, fuel pump, etc.), application, engine speed, ambient operating conditions (temperature, humidity and altitude) and other factors. This J1940 / J1995 rating provides consistent measurement to customers who may want to control the intake and exhaust features of the engine. For more information, contact Kohler Co.
