The Kawasaki FX600V is a 0.6 l (603 cc, 36.8 cu-in) V-twin 90° air-cooled 4-stroke internal combustion small gasoline engine with vertical shaft, manufactured by Kawasaki Heavy Industries LTd., for general-purpose applications, commercial mowers, heavy-duty industrial and construction equipment.
The Kawasaki FX600V has V-twin design with vertical PTO shaft. The motor uses overhead V-valves; spherical combustion chamber; cast-iron cylinder liners; metal engine cover with integrated cleanout ports; rotating grass chopper screen. The engine is equipped with electronic spark ignition and internally vented carburetor with fuel shut-off solenoid. The motor uses a high-performance lubrication system and single or multi-stage canister air filter.
The engine has an automatic compression release (ACR) system with recoil or heavy-duty shift-type starter. 13A or 20A charge coils, muffler, oil pressure switches, and shaft variations are available as an option.
Bore and stroke are 73.0 mm (2.87 in) and 72.0 mm (2.83 in), respectively. Compression ratio rating is 8.1:1. The FX600V engine produced 17.3 PS (12.7 KW; 17.0 HP) at 3,600 rpm or 19.3 PS (14.2 KW; 19.0 HP) at 3,600 rpm of maximum horsepower and 40.4 Nm (4.1 kg·m; 29.8 ft·lb) at 2,200 rpm or 44.1 Nm (4.5 kg·m; 32.5 ft·lb) at 2,200 rpm of torque.
