You know MD - I've seen a lot of sites, including dealer sites, where you can download the owners manual for free. Not so with the workshop manual. And I've visited a few sites that are selling work shop manuals - not the latest/up to date versions either.
JMHO - but if I were in the market for a work shop manual - I would go to the parts dept of my tractor dealership and get the very latest version directly from them - bite the bullet - pay the price - I've not seen a free lunch when it comes to work shop manuals.
BTW - where is your local Kubota dealer - Hooterville or Crabwell Corners or somewhere else in the Branson area??
