Hello all. I have a riding mower that dies when the deck is engaged. Any idea as to what might cause this? Thanks

Does your mower engage the deck with a switch or lever ? If it is a switch then it probably has an electric clutch, which could be shorted and pulling down your power and killing the spark.

It all depends on what kind of mower you have. Could you let us know the brand/HP/model, etc ?

Engage the blade slower?
Have you cleaned out the grass build-up under the deck? Neighbor had the same problem a while back and I went to look.... Just found the grass built up so thick the blades would no longer turn.

Something wrapped around one of the blade shafts or a bad bearing, try turning the blades with the mower shut off and see if they're binding.

Start by checking the safety swxs.

Safety switches; depending on age and model of mower, it will (may) have 3 or more safety switches which must be correctly positioned before it will start or work; i.e. clutch pedal must be depressed; must have weight in seat; blade engagement lever must be properly positioned, gear shift lever must be in neurtal, etc.,etc..... .

Sounds like the seat saftey switch to me. A common problem on all mowers.

I was actually thinking that the seat safety switch would be one we could definately rule OUT.
Note it dies when the blades come on. If it were the seat switch the mower shouldn't run at all.

Could be the reverse safety switch. Usually this switch works by completing a circuit when you go into reverse. If the switch wouldn't shut off then it'd think it were in reverse all the time.
Usually that switch is really easy to check too, especially on an MTD mower. If the shifter is down between your legs there'll be a plate there that comes off. Lift the plate and you'll find the switch. Disconnect the wire. If it mows fine its a bad switch.

I beg to disagree. It still can be the seat switch because the mower can still run and drive without the blades being in gear, (except some models in reverse with the blades on, but that is what it is supposed to do.) I have worked on many mowers over the years at my place of work and I don't know of any models that shut off the engine when the blades are OFF and you get off of the seat in PARK. The mower can run by itself with the blades OFF and no one on the seat. It is when the blades are ENGAGED and the mower out of PARK and or no one sitting on the seat when the engine can will die. If the seat switch were defective, and the blades were ENGAGED the engine would kill immediately indicating no weigh on the seat. It would also kill in all of the situations as thurlow had stated. It would also as you stated kill the engine if it had a reverse switch out of adjustment, but usually the switch fails to close leaving the switch OPEN to where the blades would come on anyways. I have worked on these for many years and usually, but not always, the seat switch is the one to fail if it is in the saftey curcuit and in PARK. My $.02
