I came across this in the Southern Utah Craig's List today:
It's in Lost Wages, NV--same place I picked up my little Broyhill grooming machine (which I now refer to as a lawn truck for simplicity's sake).
He has quite a bit of stuff with it, including the trailer.
I know the F-series Yanmars aren't near as well-supported for parts, but there appears to be a number of the machines in the country. The decal on the fender says "Power Shift" but the F16D is a standard gear transmission, if I understand correctly.
I've also heard that the engines don't have a sleeved cylinder--when the bore gets worn, you either install oversized pistons or throw the block away. This doesn't concern me a great deal if the engines in good shape now, as I probably won't put more than 500-600 hours on it before I'm too aged and decrepit to use it anymore.
The Bulldog Loader tells me that at least part of the machine came from Viet Nam/China--need to be careful of "refurbished" tractors.
I've sent an email to the seller for more information.
Your feedback is also appreciated, as always.
