Probably don’t need to but easy to start. Sharpen or replace blades annually, fresh gas 93 octane. Always busy with home and vehicle maintenance as well. Who needs a vacation

.
Why 93 octane in an engine with perhaps a 6:1 compression ratio??
@ OP
What about storage space? I sold my rider for this reason. Mine was taking up too much room in my shed and I still needed my walk behind for mowing around obstructions and close to my fence. I hired out for a year but was unhappy with the job done and their giant mowers twice damaged things here.
Been using my elderly Toro walk behind since so mowing time and effort are a bit more now an extra 20 minutes or so for my 1/4+ acre. Zero turns are always on my mind, especially this time of year when I'm mowing every three or four days but price and the room it must occupy always convince me not to.
That said if a screaming deal were to present itself I'd probably bite but keep that trusty old walk behind just in case I chaneg my mind.
