Kawasaki FX651V-CR00-S 21HP V-Twin Vertical Shaft Engine Electric Start

When long days, heavy loads, and tough tasks are on the horizon, trust the V-twin 4-cycle Kawasaki FX651V engine to help you get down to business without letting up. Durably designed for heavy use, this example of capable Kawasaki craftsmanship features cast-iron cylinder liners, a twin-barrel, internally vented carburetor, and a metal engine cover with integrated clean-out ports.

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: An advanced valve configuration that streamlines the intake and exhaust cycles. This allows the 21HP engine to breathe more efficiently, resulting in cooler operating temperatures and sustained torque delivery during heavy cutting cycles.

• 90° V-twin: The gold standard for mechanical balance. By setting the cylinders at a perfect 90-degree angle, the engine naturally cancels out harsh vibrations, providing a smoother ride for the operator and protecting the mower's frame from structural fatigue.

• Pressurized lubrication system: An automotive-grade oiling system featuring a high-volume pump and spin-on filter. It ensures that critical internal bearings are continuously bathed in pressurized oil, providing total engine protection even when mowing at steep, 20-degree angles.

• Electronic spark ignition: A digital, maintenance-free ignition system that delivers high-energy timing. This ensures reliable "first-turn" starts and consistent power output across the entire RPM range, regardless of humidity or cold weather.

• Automatic compression release: A mechanical system that reduces cylinder pressure during the starting phase. This allows the 726cc engine to spin up to ignition speed with minimal effort, significantly extending the life of your battery and starter motor.

• Rotating metal grass chopper screen: A rugged, debris-shredding intake guard. This rotating metal screen acts as a powerful centrifuge, pulverizing grass and leaves before they can reach the cooling fins, ensuring the engine stays cool in the messiest field conditions.

• Multi-Stage canister air filter: An industrial-grade filtration powerhouse. It utilizes a cyclonic pre-cleaner to eject 90% of dust and particles before they hit the primary filter, doubling service intervals and protecting the engine in punishing, dry environments.

• Cast-iron cylinder liners: Durable, high-density iron sleeves that provide a rugged, wear-resistant surface for the pistons. This premium feature ensures the 726cc engine maintains long-term compression and structural integrity through years of commercial use.

• Metal engine cover with integrated clean out ports: A professional-grade, impact-resistant shroud. The built-in clean-out ports allow operators to quickly blow out trapped debris from the cooling system without having to disassemble the engine.

• Heavy duty shift-type starter: An automotive-style solenoid-shift starter motor designed for maximum reliability. It ensures positive gear engagement every time, providing the high-torque power needed for the constant start-stop cycles of a professional crew.
