Our C Series line of engines encompasses 5 different models, with hp from 5 to 73, and speed ranging from 300-800 rpm. The C Series has been tested by time in the field for over 60 years and is a proven worker with incredible longevity and durability. We continue to refine the design to provide ever greater efficiency of operation and reduced emissions.

Arrows K Series engine is our newest addition to our single cylinder line of engines. With 6hp and 400-800 rpm, it is a perfect engine to run in place of an electric motor in situations where dependability, lack of electric, availability of natural or wellhead gas or longevity of the engine are factors. This diminutive engine features the same qualities as our C Series, including the heavy flywheel to provide smooth high torque operation at low speed

These are beautifully engineered engines, in the field for more than 70 years, are one of the most durable and long lasting engines anywhere.
