Kohler Engines – a KOHLER Company based in Italy – have been manufacturing engines since the 1920s. Kohler Engines produces a wide range of gaseous, gasoline and diesel engines, from 4.5 to 140 hp, which are supplied to equipment manufacturers worldwide in the lawn and garden, commercial and industrial, agricultural and construction markets.

Kohler engines are over 100 years old and have built a reputation supplying single and multi-cylinder high quality gasoline and diesel engines to diverse industries around the globe.

They were the first company to supply Electronic Fuel Injection (EFI) gasoline engines to the lawnmower / grasscare market over 20 years ago and more recently they built the world’s first Tier 4 diesel engine (KOHLER Diesel KDI) without a DPF. This revolutionary engine provides operators with a Tier 4 final solution and significantly lower operating costs.

Their innovation continues and they were one of the first engine manufacturers to release Stage V compliant diesel engines and now have a range of engines from 5kW to 100kW with Stage V compliance.

We also have a comprehensive range of single and twin cylinder gasoline engines which are European Stage V compliant with power ratings from 4.5Hp to 38HP.

Kohler’s latest innovation is the ground breaking K-HEM hybrid energy module which combines their renowned KDW1003 or KDI2054TCR engines with a 48V electric motor.  Specifically designed for applications with a consistent base load requirement, but also the need for intermittent peaks it removes the need to specify a much larger single engine to cope with peak demand.  The K-HEM system won the prestigious Diesel Progress Award for engine of the year <175hp in 2019.
