Loaded with EFI to Make Mowing Better.
Everybody knows the best mowers are powered by the best engines. That’s why we designed the fuel-injected 7500 Series™ EFI engine. With this powerhouse, it’s all about easy starting, reliability and fewer trips to the gas station—so you can have more time to relax.

4-Wire Oxygen Sensor
The oxygen sensor measures the oxygen content in the exhaust gas and calculates the appropriate fuel flow. This sensor completes the closed-loop system.
Throttle Body
The throttle body includes the air temperature sensor and throttle position sensor. These sensors provide information to the ECU for precise fuel metering under all conditions and loads, resulting in best fuel economy and load response.
MAP Sensor
The manifold absolute pressure (MAP) sensor provides instant manifold pressure information to the ECU. It calculates the air density, determines the air mass flow rate, and adjusts for changes in the weather and altitude.
Fuel Injectors
Fuel injectors are designed and positioned to optimize targeting of fuel into the cylinder by shortening the distance the fuel has to travel. This results in improved load response and starting, better fuel economy and lower operating costs.
Inductive
Battery Ignition
The inductive battery ignition coils provide quick, reliable starts by delivering full spark energy during cranking.
Electronic Control Unit
The electronic control unit (ECU) is the engine-mounted computer that continuously monitors and adjusts the amount of fuel delivered and ignition timing for optimal performance.
Onboard Fuel Module
The onboard fuel module handles high-pressure fuel delivery and fuel pressure regulation. Unlike all other EFI System, this is located directly on the engine, eliminating the need for a return fuel line to the tank.
