As I mentioned in: http://gardentractor...t-cut/?p=385772
I'm looking at a possible purchase of a DOA three cylinder Kubota that has come for sale and am interested in seeing if there is a difference in the deck's noise level. If I get it (and get it running) I will report. I'd considered swapping the decks but read somewhere that the RC40 deck is almost too large for the two cylinder. I suspect the three cylinder has the RC44 or 48.
I picked up the G6200 ($400/1000 hours) and while the 48" deck is in very good shape, the rest of the system looks its age; the hood has seen it share of bumps and bruises as this is typically the first casualty on a Kubota Mower. Hydro fan is mostly unscathed. Dog got the seat, seat pan has some holes. I power washed off 30 years of frame and component goo.
The motor has less than 200lbs compression on any cylinder. Fuel flows, plugs glow, starter cranks - doesn't start.
When I tear it down (my first motor rebuild ever!) I will asses what it needs and then order the parts individually. A kit would be cheaper but I can't seem to find a D640 kit. I've found "rebuild kits" for D600's to be plentiful but haven't found a one for a D640. Still looking.
