Subaru Industrial Power Products expanded its engine line earlier this year with the introduction of the EH90 and EH99 Big Block V-Twin Engines. Although Subaru was already a big player in the V-Twin engine market, customers were asking for larger engines that could meet EPA requirements and handle more rigorous applications. The engines are ideal for equipment like concrete polishers, riding trowels, utility vehicles, zero-turn mowers and ride-on blowers.
The 35-horsepower EH90 and 40-horsepower EH99 are extremely durable, low maintenance and feature heat-reduction technology. Both engines are 999cc and have heavy-duty connecting rods, large crankshaft bearings and three-ring pistons. The hardened exhaust valve and seats can handle high temperatures, which improves engine performance, efficiency and overall life of the engine. Our temperature sensor triggers an alarm to alert the operator to high temperatures before damage occurs‚ and the oil pressure sensor automatically shuts down the engine when pressure is too low.
In addition, the standard four-cycle OHV (overhead valve) gasoline engines feature a dual element air filter that protects the engine from dust and reduces maintenance. An optional Donaldson® canister style air cleaner has an inlet pre-cleaner, which offers additional filtration by removing a majority of the particles before they reach the filter, thereby minimizing maintenance and extending the intervals between cleanings or filter changes. The engines come standard with a low-mount air filter.
Both engines are backed by Subaru’s 5-year limited warranty.
