Welcome to JUST ANSWER small engines, let me try to help you !! I don't know it all, but maybe together we can get you a satisfactory answer!

Expert:  Curtis B. replied 1 month ago.

What have you done? Spark plug replaced? Fuel and air filter changed? The carburetor fuel bowl been drained? Valves ever been adjusted?

Expert:  Curtis B. replied 1 month ago.

Sounds like lack of fuel when the engine needs extra fuel.

I should have been more specific, engine makes enough power for tractor to climb steep hills, can over power the parking brake. It's when parasitic electric load is applied the engine starts to die, however the same battery has been starting the tractor for last 8 years

!! Really, your battery is 8 years old? Wow, that is a first. I know you won't believe it, but , check the battery voltage when you turn on the blades . If it drops below 12 volts, replace the battery!

Engine has electric fuel solenoid in the carburetor, if voltage drops below 12 volts, this solenoid can try to cut off the fuel supply.
