Why does my lawnmower die when I engage the blades?
My 1988 John Deere 175 Hydro Lawn Tractor dies when I engage the blades.
If I disengage the blades quickly after engaging them it will normally stay alive.
Before it dies it does do a power down; it almost sounds like I've turned the key off but I think a key turn off takes a touch less time.
It just started doing this out of the blue. When it initially happened the mower died in the middle of a cutting. After that it wouldn't start. It was suggested to me to replace the fuel filter, so I did. Mower still wouldn't start. I walked for maybe a half hour and came back to the mower starting right up. From that point on the mower starts and runs like it always has but now will not stay on when the blades are engaged.
The blades spin like normal if I reach under and push by hand.
