A Honda GX690 V-Twin Series Engine powers the D-15. Proven reliability is not an option while on site. The GX690 is a workhorse that boasts solid performance and excellent fuel efficiency. Power is transferred directly to the air-end via a direct drive system. No belts to slip or cause on-site breakdowns. The motor is coupled to the air-end by means of an aluminium cage and this helps to reduce the weight of the drive system. The oversize air-end features high efficiency and long service life. It is designed to withstand the harshest operating conditions, day in and day out.
