I once worked near an MTD plant in Canada. They made JD, White, Toro, Craftsman, MTD, Cub Cadet, Yardworks (and possible some others). At the time you could easily tell as they all looked the same - just color and sticker differences. Shape of the hood, styling - all the same.
My dad had a Kubota G5200 lawn mower 30-35 years ago. He used and abused it the whole time. We rebuilt the mower deck twice and boiled the coolant out at least 10-12 times, each time the engine would just stop (the rad screens would plug up with grass and weed debris stopping air flow). We would wait an hour or two, add some water back in the rad and it would start right up and run normal again. You couldn't kill it. After 20+ years it finally wasn't running right so my dad got rid of it. A nephew picked it up and changed a second fuel filter we never knew existed and it ran like a charm again. You can't kill those Kubota 3 cyl. diesels from the 90's.
One of the things I focus on after use is rinsing out the radiator fins.
Particularly, during the summer when it's dry.
I also discovered that on my machine at least: Filling the oil to the Fill-Line is a no-go. Keep it at or just above half. Not a big deal if you fill it all the way... The machine will just burn or puke it out until it's at the level that it likes. LoL
