In the OP's defense, I own a LX2610. The owners manual is almost good for the basics. But, other than that, it is campfire starting paper. More than 10% of it is dedicated to safety and liability stuff. It's pretty bad.
I don't own an official "Service or Repair Manual" and I have considered buying or downloading one. But if it's anything like the Owners Manual I'm sure that it's more campfire starter.
Kubota really does build fine equipment, but they skipped a real owners manual.
My 2017 Ford Super Duty Manual, is over 500 pages. So is my late model Jeep and Dodge. My Kubota LX2610 Cab owners manual is 149 pages including the index. 26 pages of that 149 is warnings.
