I will be mowing once maybe twice a month from March/April - September/October depending upon weather.
Will be using ethanol free fuel with Startron additive.

There is no fuel shut off between the tank and the fuel pump. Should I install a shut off and run it dry after each time I mow since it will be sitting for a month?
If so should the shut off go after the inline filter to keep crap from building up in the shutoff?

The mower is kept in a metal barn that just stays hots as balls all summer long.
It currently has a flooded U1 batter that is 2 years old and I plan to put a solar battery maintainer on it.
Plan to swap to an AGM when this battery calls it quits.

During the winter months I plan on taking the battery in the house and leaving it on a maintainer since it will see no use for 4 months.
Figured shutting off fuel and leaving fuel in the tank is not an issue since the tank is plastic. But in the winter the barn is cold as balls at time which stretches below freezing for weeks.

Sounds good.

I haven't had any issues (other than wear and tear) from having mine being stored as yours has.

I bought mine used in 2006 and it has been running good ever since.

You say fuel pump, is it fuel injected? If so I would not run the fuel pump dry because that's pretty hard on them.

If it's carbureted with just one of those vacuum fuel pumps you might install a fuel shut-off to drain the carb come Fall but it shouldn't need drained after each use if it'll be used again in a month or two.

I would see no reason to do that if you run ethanol free and put startron into the fuel especially with a small window between running of a month...

Ethanol free fuel and a battery maintainer should be all you need. My mower sat all winter because I never needed to plow this year, and it started fine when it was time to mow in the spring.

You mean I’m supposed to mow more than once a month?

My last cut is in Dec and my 1st is mid March. I don't do anything but fill my gas tanks with Kroger gas treated w/Startron. Been doing it this way for 40 years.

Guess it all depends on what you mow.
At my house I mow weekly. It’s tiny and my Honda push mower does just fine.
I use ethanol free and run it dry my last mow of the year.
Come spring it fires right up on the 1st or 2nd pull.

Was not sure if I should handle the zero turn the same way or not.

Year, Make, Model of mower and engine?

E0 and Startron will be just fine . Don't overthink it .

At least 10 years old. John Deere Z225 with an 18.5hp Briggs.

Has always used ethanol fuel prior to me acquiring it.
It currently starts and runs like a champ. I just did a full service on it. Oil, filters, spark plug, new blades.
Also replaced the steering stabilizers as one was fully blown and lost a nut so it was detached from the frame.
Well, truth be told my 7 year old swapped the steering stabilizers.

If you go by the widely-recommended "cut off no more than 1/3 the grass blade), you would want to mow sometimes more often than weekly, and sometimes less often than weekly. In this area that would mean every 4-5 days in April and May, and maybe every ten days in July and August.

When I was running a mowing firm, I would map out a schedule/calendar at the beginning of the season so customers would know what days to expect the crew (with rain provisions of course). This also helped with manpower prediction, hiring, and scheduling, and helped differentiate us from the competition. We would mow 28-30 times a year for most customers, with some high-$ folks getting more cuts.

Yeah selogic is correct.
It uses a carb and the cheap plastic vacuum fuel pumps.

Few bucks to replace if the diaphragm fails.
(sadly, if it does, you won't get a tiny Z-turn)

When I lived in Montana, I’d park my Kubota zero turn after the last mow, fill the take and walk away. In the spring it would immediately fire up. I did this for at least 10 years.
