ECH730 - 23 hp 747cc

New Engine Horsepower Rating Standard
The new SAE J1940 standard requires all engines produced after and including October 1, 2013 must be within 95% of the declared rated power and torque as opposed to the old standard of 85%. SAE (Society of Automotive Engineers) has also stated that the engine manufacturer must disclose the rpm for rating and with the GROSS (SAEJ1995) or NET (SAEJ1349) horsepower.

Note: Engine produced before October 1, 2013 are labeled and rated by the old standard.


In most cases the engine displacement (cc) has not changed. Example: Model CH740 with 725cc, before it was rated as 27hp and will now be rated as 25hp under the SAE J1940 standard. The engine has not changed, only how it’s rated under the new SAE J1940 standard.

Engine Type:

4-cycle, gasoline, OHV, cast iron cylinder liners, aluminum block, electronic fuel injection

* Length is front to rear of engine. Width is valve cover to valve cover. Height is mounting surface to top of air cleaner.
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. Engine Engineering Department. Kohler Co. reserves the right to change product specifications, designs and standard equipment without notice and without incurring obligation.
