Your seller did you a good favor
Nice lawnmower, you probably won't need a mulching plate after you get your gatorblades installed...but like you said it is cheaper & easier to make a plate if you decide you need it.
I don't know how old it is, I sold a used one similar to that about 15 years ago, I think I got $1500 for it, but all it had was just a mower deck.
Tire tubes will inexpensively fix tires with decent tread that are not split. If you have a local tire shop, you might ask about having the tires filled with anti-freeze & water, for the weight, as those lawnmowers work better with a low center of gravity.
Personally I would rather spend money on frequent oil changes... (approx. every 20hrs., or whenever it gets to the ADD mark, or whenever it has a brown color)...than buying oil filters each time. If the oil change time is extended to 50 hrs. as Kohler recommends, the oil will be black, regardless if you changed the filter or not. I would never spend extra money on synthetic oil. That engine is recommended by Kohler... multigrade oil, as it has hydraulic lifters...those lifters will give you trouble if you use straight weight oil.
If you gotta spend money on filters, spend it on fuel filters, & air filters, (1) extra foam wrap prefilter is handy to have & should be serviced often. Always make sure that the air filter wing nut has a red rubber seal in place and remains tight, this wing nut is different than the nut on the top of the cover. Inspect your PVC tube often, do not run the engine if that tube is leaking or cracked, as dirt will go directly into the engine & quickly ruin it. As old as yours is, you might consider getting a new PVC tube. Make sure your dipstick seals completely, as this too will allow dirt directly into the engine.
Find a bottle or can that will fit over your gas cap, the idea is to not allow rainwater to contaminate in the tank. When you fill your lawnmower, try not to empty your supply tank into your lawnmower (most of the contaminates settle in the bottom of the supply tank, so don't pour those into your lawnmower, leave an inch of gas in your supply tank).
For your seat, not much can be done once they split, try not to let the foam get rain soaked, as it will rust out the seat pan & could cause trouble with the seat switch. Sunshine dry cracks the vinyl over time, eventually it will get hard & brittle. Try not to take the windlace off the rim of the seat cover, as reinstalling it can be difficult, check the 'bradded area' where the windlace comes together with a pair of pliers, keep it crimped tightly. You might try making a patch to slide in under the vinyl, add epoxy glue, and another patch over the outside, make the patches larger than the rip.
Find an aftermarket plastic battery tray of some sort for it, as those were bad about spewing acid and rusting chassis components, all the way down to the deck.
I would lube everything that moves. I would replace the fuel line & gas tank grommet.
