When the mower deck safety switch is working correctly - you can engage the blades and the mower will not die. Well if that switch isn’t getting pressed or depressed correctly by a rotating piece of metal connected to the engage wire or in my case, it’s all metal pieces - I have a SABRE and there’s a rod with a spring on it - that rode that goes through the spring will get out of circle and wear out to an oval shape. well there’s a shape like this [______] now imagine a spring and washers on the inside of that on both sides - well how the bar stays inside of that - there is two little bumps - well once that metal bracket thing is worn to an oval that bar will go right through - so there is NO spring action - that spring action is just enough to put pressure on the switch - when there’s no spring action, that switch can not get pressed. When you go to start the blades and your mower is running fine but it dies when you start them - that button is not getting pressed in all the way - due to that slack - and it will kill the engine. Now that rod and spring may be just fine - but there is a nut at one end - adjust that nut in or out - that rod is threaded. You may need just a bit of an adjustment to get it to push that button in all the way. - due to the places on the deck it mounts to and so on getting a bit out of wack or just wear and tear over time. This is the answer to the problem - bar none. Personally - I got sick of hitting bumps or going on hills and the mower dying so I bypassed every stupid switch. Lots of tutorials on youtube and online.

If the mower runs just perfect until you go to engage the blade - this is the issue.

WARNING - IF YOUR MOWER DIES WHEN YOU GO TO ENGAGE THE DECK./BLADES - YOUR ENGINE STOPS GIVING SPARK - SO YOU WILL HAVE A HEAD FULL OF GASOLINE ON TOP OF THE PISTON (S) - BEFORE ATTEMPTING TO START - REMOVE THE SPARK PLUG (S) AND HAND CRANK THE ENGINE A FEW TIMES - IT WILL SPIT THE GASOLINE OUT OF THE SPARK PLUG HOLES. - REPLACE SPARK PLUGS AND YOU'RE SET AFTER YOU MAKE THE ADJUSTMENTS NEEDED OR REPLACE THAT BAR./SPRING DEAL.

IF YOU DO NOT DO THIS - YOU WILL BE STARTING YOUR MOWER - AND YOU WILL BLOW THE ENGINE - MOST LIKELY IT WILL BREAK THE PISTON ARM (S) AND POSSIBLY THE CAM (S) - DO NOT BE THAT GUY!
