The Kohler LV675/LV675S is a 674 cc, (41.1 cu·in) V-twin liquid-cooled four-stroke internal combustion gasoline engine from the Aegis series, manufactured by Kohler Co.
The Kohler LV675 engine has an OHV (overhead valve) design, vertical PTO-shaft, pressurized lubrication system with Gerotor oil pump. This engine is equipped with a carburetor with a fixed main jet and electronic ignition system.
It has an 80.0 mm (3.15 in) cylinder bore and 67.0 mm (2.64 in) piston stroke. The compression ratio rating is 8.5:1. This engine produced 23.3 PS (17.1 kW; 23.0 HP) at 3,600 rpm of horsepower and 44.0 N·m (4.5 kg·m, 32.4 ft·lb) at 2,400 rpm of torque.
The breakdown of the engine code is as follows:
- L – Liquid-cooled
- V – Vertical PTO shaft
- 675 – Numerical designation
- S – Electric start
