Is there an online manual for the Kubota V2203 Diesel engine? I believe this is the engine in the Bobcat 2010 S150. It may be the V2203MDI. Not sure the "MDI" maters
I think the M-DI refers to the engine being a newer tier 4 engine rather than a tier 2. In a nutshell, its pollution stuff. As far as a manual goes, I wish I could help. Kubota makes a great engine, so hopefully you wont find a manual necessary.
