Thought of that , however used the tractor all winter for snow blowing and had no issues with this behavior. Changed plugs , fuel filter , air filter and cleaned carb. Tractor ran great all winter. Seems that something is happen when the mower deck is engaged that does not take place when the auger is engaged with the same lever.
Engine starts cutting out after engaging mower deck

Marko, I wouldn't get hung up on why it worked with the snowblower. It isn't working with the mower, and that's what you want to fix. To eliminate enine issues try putting it in high gear and running up a steep grade; if it runs fine then it's a safety switch causing your problem. Locate the kill wire by following the wire from the reverse switch, and disconnect it.
Do you have a meter? Do you know the model number of your machine? Speculation on why it worked with the snow blower may not be that useful.

I've located a wiring diagram at Parts and Diagrams for White Outdoor 13A1686G190 LT-15 (1997) .
Looks like the ground path is yellow/black wire from reverse switch to deck switch (connects with another yellow/black wire from seat switch), out on yellow wire to ignition switch. A yellow wire connects the engine magneto to the ignition switch via a connection at the clutch switch. The engine kill function works by various combinations of the clutch, PTO, reverse, and seat switches grounding the magneto. Other combinations will prevent the starter from engaging.
I'd print a copy of the wiring diagram and use a meter to diagnose the problem. Look at the wiring at the PTO(deck) switch. There are two inputs at the upper leg: the seat switch and the reverse switch. Here the where the decision is made that if the seat is empty or reverse gear is selected, and the deck is engaged, the magneto is killed. Since the engine runs until the deck is engaged I'd say the problem is from the PTO (deck) switch back to the reverse or seat switches. Try disconnecting the yellow/black wires at the PTO (deck) switch.

I had a similar problem. Ended up being low voltage on the battery.
jhwentworth - I check the continuity between the seat and reverse switches to the deck switch over yellow / black wire and all is Ok. Found no broken wires or an damage of the wire looms etc. Did notice that the battery is not 100% even though it started right up wonder if the low battery voltage condition that General Lee posted is the issue. I get a new battery and test again. Just out of curiosity , once the engine starts I though that the mag took over providing spark to the plug and not off the battery ?

Low battery voltage doesn't seem like a viable issue here. Look at the wiring diagram; does it seem that the battery is the source for the ignition? Kill the mag, kill the ignition.
Disconnect the yellow wire at the deck switch.
Disconnect the yellow wire at the deck switch.
Wouldn't disconnecting the seat switch and reverse switch at their respective places solve the same things as disconnecting them at the deck switch. I'll give both a try but have a hard time believing that if I have full continuity on this is the problem. The seat and reverse switches are simple contact ones so testing them and seeing of there are issues with this is fairly easy.
I have to get a new battery anyway as having on the trickle charger for the afternoon did not yield anything.

I am fighting the same problem with a Dixon 4421, B&S 13 hp motor, electric clutch mower engagement ! I too wanted to bag leaves! LOL!---as soon as deck engage switch is flipped, motor dies!---Runs uphill full speed, full rpm, just dont turn mower deck on!---Got me stumped too ---NEVER had one do this before!---has new F&F battery fresh otta the store just put on it!---still got the problem!
Didnt mean to hijack your thread, but I am getting desperate here as good weather is not going to last much longer and I have a lot of yard to clean! thanks; sonny 580
