Question about Craftsman 17.5 hp 42 in. Deck Lawn Tractor - CA Model
Mower turned upside down to replace blades. Engine is B&S 6.5 Hp. (Easy-Start).
OOOh I don't recomend turning any 4 cycle engine upside down for any reason , i'll bet the starter won't even turn it over now, 1st your gonna need to replace engine oil to proper level , second your gonna need to locate valve (locker) this canbe ident by a small tube comming from it to carb , remove this cover and clean/drain oil from here and last remove spark plug tilt engine that direction and remove as much oil as you can attempt to turn engine over with key off by hand or with jumper on starter several times to get it moving again , clean plug with solvent and reinstall , also reinstall valve cmpt cover and tube , attempt to start might take several tries to get fresh fuel over to cylinder to fire or you might need to reclean plug several times

It may think you are in reverse and is killing the motor to keep you from backing up with the blade running. Look for switch that is telling it when you are in reverse, maybe it is stuck with grass or other debris. another possibility is that the blades are jammed and they are stalliing the motor. Mines stalls easily when cold.

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.

When you move the lever and engage the blades you are also engaging the belt that drives the blades and sits on top of the mowing deck. Chances are that belt either came off one or more rollers, or broke. The only way to check it out is to get down and look on the top of the mowing deck. Get back and let me know what you find.

maybe the safty switch under seat might be starting to go out if that switch doesn't work the blades wont come on at all for safety

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.
