Features:
Engine performance, by the numbers.
- From power and torque numbers to engine features and more, the following is here to help communicate engine performance details and capabilities. Be sure to consider these specs to help ensure the engine you’re choosing is a match to your mowing needs.
Overhead v-valve
- Designed with an overhead V-valve (OHV) configuration, this engine optimizes the intake and exhaust flow for improved combustion efficiency. This layout enhances power delivery while reducing fuel consumption and heat buildup, ensuring the engine runs cooler and lasts longer.
Integrated Clean-Out Ports
- The engine features large, integrated clean-out ports that provide quick and easy access to the cooling fins. This user-friendly design allows operators to clear away grass clippings and debris in seconds, preventing overheating and maintaining peak performance during long shifts.
90° V-Twin
- Engineered with a naturally balanced 90° V-twin architecture, this design cancels out internal engine vibrations for a smoother operating experience. The balanced layout not only increases operator comfort but also reduces mechanical stress on the mower’s frame and components.
Pressurized Lubrication System
- Equipped with a full-pressure lubrication system, the engine uses a high-efficiency pump to deliver a constant flow of oil to all critical internal bearings. This automotive-grade protection ensures the engine remains lubricated even when working on steep hills or under extreme commercial loads.
Electronic Spark Ignition
- The precision electronic spark ignition system ensures fast, dependable starts in all weather conditions. By providing a high-energy spark at the exact moment it's needed, it eliminates the frustration of "hard starts" and contributes to a smoother, more consistent idle.
Automatic Compression Release
- Featuring an automatic compression release (ACR) mechanism, the engine significantly reduces the cranking force required at startup. This places less strain on the starter motor and battery, allowing the engine to turn over effortlessly and reach operating speed instantly.
Internally Vented Carburetor with Fuel Shut-Off Solenoid
Rotating Metal Grass Chopper Screen
- To combat heavy debris, the engine uses a heavy-duty rotating metal grass chopper screen. This system actively shreds grass and chaff before it enters the cooling fan, preventing clogs and ensuring a steady stream of air reaches the engine block.
Dual Element Air Filtration System
- The engine is protected by a high-capacity dual-element air filtration system, featuring a reinforced primary filter and a secondary safety element. This multi-stage defense captures the finest dust particles, ensuring only purified air enters the combustion chamber in the dirtiest mowing conditions.
Cast-Iron Cylinder Liners
- Built for professional durability, the heavy-duty cast-iron cylinder liners provide a rugged, wear-resistant surface for the pistons. This robust construction significantly extends the engine's service life compared to standard aluminum bores, making it a true commercial-grade powerhouse.
