If I recall, the documentation is in 3 sections for Bobcat. 1) Operators manual 2)service manual, 3) diagrams containing all of the component part numbers
Thus was for a commercial piece of equipment, don't know if it is the same for their re-badged tractors. If you didn't have the 3rd manual, you only had a vague idea of what you were replacing and clarification required going in to the dealer and looking at the screen with the dales guy. The nearest Bobcat dealer is about an hours drive away open Mon-fri. So I have to take time off work to go and see them. I ended up photocopying pages out of the manual and marking the parts I wanted and sending it by mail.
For my equipment there was nothing I could look up on line.
On the Compact tractors you just got a owners manual. You could get a work shop manual if you wanted. I guess you could get a parts diagram, I know some of the Kioti dealers have parts of the tractor online but not all of it.
