Ours had the diesel... Can't remember which, but it was pre emissions era. Thing was a tank. Like literally, it was a tank.
Same thing for the park I was at. River cut through it as well as a major tributary, so there was swamp everywhere. I was their only farm kid, so I spent the summer on a Kubota with a brush hog. Same story there, damn ventrac would handle areas I'd have the 4x4 Kubota sunk to the axles.
Didn't care about hills, grades, cliffs if the duals were on it.
Got to mess around with its big brother once, an Aebi. Always thought they were ideal for ag in places like PA. We farm on cliffs here lol
