I currently have a 18 HP Yanmar with 14 PTO HP. I'm looking for an upgrade in the same basic size.....loader, power steering, HST, etc.... The extra 4 HP of the 2800 would be nice on the PTO, but that's about 5 hours per year for bush hogging. Probably not enough for me to take the chance on the turbo. Typical use would be more pulling and hauling wood, moving dirt/gravel, scraper blade work, etc.... Like you, I want my next purchase to last many years so I'll probably steer clear of the turbo.
How does the hydro perform? I know that in some small units (Kioti specifically), the high range is basically useless.
Thanks for your input.
