I have a 13.5 HP Yanmar which is about25 years old and I need a little bigger for our yard and some farm chores (on a real farm). I'm looking at a 27 HP 276D with a power shift which is about the same vintage as mine. It shows about 900 hrs and thats how the tractor looks. I know Yanmar engines are near bullet proof but I'm wondering about the powershift. And I'm wondering about parts availability, for the whole tractor. This is not a grey market tractor. Any comments would be appreciated
