回答“Why does my engine die when the blade is engaged?”It sounds like you have a loss of power when you put the extra load on the engine. A possible answer could be as simple as changing or cleaning the air filter. A dirty air filter will allow the engine to run but too rich. The clogged filter acts like another choke. But when the load is applied to the engine, it is too rich and so it dies. Make sure that you are running the engine at full throttle when you do engage the blades.
