Scratching my head here.
Worked fine last time used.
Set in garage through winter time. We had some cold weather, maybe down to 17F for a night or 2, but that is gone.
I tried to start the engine today - no go.
1. starter spins fine
2. tank half full
3. Choke up, as it should
4. PTO down, as it should be'
5 Parking lever up, as it should be
6. I'm in the seat, as I should be
7. throttle lever at about 75%, as it should be
Starter just spins engine, not a single catch.
After about 10 attempts, battery started dying. Then, engine BACKFIRED like a gun. LOUD.
Oil level is fine.
Have charger on battery, but a bit hesitant to start it again, after battery charged. That backfire scared me. It backfired few times before, during normal use. It's still under warranty, but my problem is - I don't have trailer to take it down to shop, so I'd rather figure it myself.
To be honest, it was kind of finicky to start always. Oh, and it's Toro Twin engine.
Any thoughts?

Maybe one of these service manuals will help you out. https://www.toro.com/getpub/117255

Thank you.
Is it safe to crank it again after that backfire?

What the heck...
So I went back to the mower..
Started with removing post fuel filter hose - no gas.
Removed pre filter hose - no gas.
Well, maybe it needs pump to engage, OK..
Removed charger clamps off the battery terminals
Turned key into #2 position, whatever that is. Some faint noise came from the engine, like some relays buzzing
Removed fuel line from filter again - no gas.
Out of curiosity - STANDING BESIDE THE MOWER - turned key to Start. Starter spun engine, I turned it back to #2 position again.
Then, like - why it even spun the engine? - turned it to Start position - ENGINE FIRED RIGHT AWAY!
Took it out for a spin, everything works, as it should!
Why did it even start with me not in the seat?
Weird. Oh well.

Most manufacturers but not all put the seat switch in place to kill the ignition when you get out of the seat. This is so you can't get off while the engine is running unless the pto is disengaged and the control levers are out or start position. This is so you don't get run over or chopped up by the mower.
Some manufacturers put a seat switch so you need to sit in the seat to start and run. So it depends on the manufacturer.
Here is a link for the manual for the mower -- next to last page is the wiring diagram.

I would pull the spark plugs and replace them. If fuel got into the intake, they may not have fired correctly and caused the backfire. Many mowers can run when you're out of the seat if the parking brake is on and the PTO is off.

What oil do you have in it?

Replacing spark plugs is usually unnecessary. You can clean, gap, and blow them out with an air compressor blow gun. Spark plugs in small engines usually last for several years.

I've seen many bad plugs, especially if oil or fuel soaked.

You can light the spark plugs with a torch and blow it out with a blow gun. Doesn’t mean the plugs need to be tossed in the garbage.

I have had problems with the fuel filter, the engine had a cough and the filter was very clogged.
You have to check it often and perhaps a slightly older one wouldn't be bad.
The other problem I had, almost when I new the machine, was the carburetor fuel solenoid valve. It started out failing from time to time until in the end it didn't work anymore.
Remove the cable and needle from this valve, and... the problem is over.
I don't think the carburetors overflow.
Another problem was the front wheels, ... very delicate. I ended up putting some bushes,... perfect
My translation is from Google, sorry for the language kicks...
