What makes our engines better? Two things: A better, fully integrated fuel system and higher quality manufacturing. Most mower engine manufacturers will tell you torque is critical to the performance of an engine, and that’s 100% correct, but what is really critical is what happens to torque as you put the engine under load. In most cases, you get a drop in rpm, as much as 25%. That’s the bogging down sound you hear as you go through heavy grass. Our TillotsonTCT fuel system virtually eliminates engine bog so you can maintain torque under even the heaviest load.
