[Vwdiesel] OT: Kubota 3cyl Diesel tractor-opinions sought

[Mike & Coreen Smith]

Pardon my slightly off-topic post, but you guys are the BEST when it comes
to diesels.

I have a chance to get what I think is a good deal on a 1998 Kubota Lawn
tractor.TG1860
3cyl 18hp, 43.9CI,(719.4cc) diesel.  54" deck, 650hours on the machine.
I currently have 2 acres of old farm field to mow. Bumpy and rocky, but
mostly flat-ish terrain.
I am beating my poor spine to death wtih an old 1988 Murray (MTD) 14hp/42"
cut right now.

What should I do?

Is the Kubota a reliable machine with that many hours on the engine?

Thanks!
p.s.-still looking for another VW diesel BTW.
