my riding lawn mower loses power and nearly cuts off when I engage the blades?
We changed the spark plug and fuel filter, cleaned the air filter, and checked for obstacles in the belt that engages the blades. The battery was replaced last summer.
are you at full idle? If so chck to see the pulleys are not worn out and need to be replaced. Take the drive belt off and move each pulley by hand they should move freely. Other that that it would most likely be carb, timing or ignition
