Question about Garden
When the blades are engaged the lawn tractor shuts off.
This sis a micro switch issue, start by checking/replacing the seat switch, make sure the block connecter is fully pushed home onto the micro switch.

Good answers, but if not switches, does it shut down at low or higher RPM? At low RPM I have seen seized blade shaft stop engine when engaged. Check each blade to make sure they are free to spin while disengaged. FREE-PPV.com

Yes sounds like it's a saftey switch, it could be your seat or the reverse switch is stuck in

Check one of the four Nuka safety switches one on the brake pedal one on the blade left 100 C and the 4th one is on the shift lever I believe

Try pulling on the cable coming down to deck. This cable might be your problem. Also check that the spring on the end of this cable is present and functional.

Did you try to disengage the safety feature that should shut the tractor off when the blades are engaged and the tractor is placed in reverse? I believe that it is located under the shift leaver

I'm betting that you need a new safety kill switch - probably the one underneath the seat (the spring-loaded plunger switch that won't let you use the machine without your *** in the seat). Could also be the one behind the "dash" that is associated with the blade engagement mechanism.
I know that the under-seat-switch cannot be bypassed or it will disable the machine in the exact way that you described. Why do I say this? Because I just tried to bypass my own "***-in-the-seat-safety-switch" on my very own 15.5 HP, 42" Sears tractor, and it responded by punishing me - the absense of the switch caused the motor to cut out when I tried to put the machine in gear AND/OR engage the blade. It seems to have some measured capacitance - the absense of same seeming to interrupt the ignition timing enough to shut the motor down when you attempt to get anywhere past neutral or engage the blade. These "safety" switches may be needed by a very few who prefer to be drunk while they mow lawns on steep slopes that their tractor mowers were not designed for, but I find these items to be troublesome and enfuriating. My trees shed a lot of sticks in high winds, and I can't stand shutting the machine down and restarting it EVERY SINGLE TIME I have to dismount to clear sticks or other obstructions out of my mowing path. This is an obnoxious, "nanny-design" feature that desparately needs to be discontinued. It also makes both jump-starting the tractor and electrical troubleshooting much more difficult than they should be. The tractor should let you dismount without shutting down, as long as you have disengaged the blade and shifted into neutral. It should also let you jump start with jumper cables - impossible to do with your rear end in the seat. By the way, call Manufacturer's Supply, Inc. at 1-800-826-8563. They may have a replacement - their item number 31-9664 might do it, but talk to them first. I'm calling them tomorrow. Good luck.
