Subaru introduces a new line of diesel generators powered by Hatz four-cycle, single-cylinder diesel engines. The RGD3300H uses a 6.8-hp Hatz 1B30 engine with a rate output of 3,000 watts, while the larger RGD5000H (pictured) uses a 9.9-hp Hatz 1B40 for a rated output of 5,000 watts. Both models have electric starters with recoil backup, while GFCI receptacles and fuseless circuit breakers protect the current level. Both models also include a full-power switch, voltmeter and 12-volt DC charging, as well as a spark arrestor that lessens both noise and ignition risk. Large 4.4-gallon fuel tanks allow for hours of continuous operation, while a low-oil shutdown system prevents damage to the engine should lubrication levels drop.
