Bobcat CT225 Compact Tractor Service Manual (SN A59B11001-A59B99999)

A CT225 compact tractor spends its life mowing, moving dirt, running a loader, and doing all the odd jobs around a small farm. The service manual is what you pull out when something quits, starts leaking, or you're about to lose a whole weekend chasing a problem. It's written for people who actually turn wrenches and need the right sequence, specs, and diagrams to get in and out of a repair once.

What this manual helps you do

  • Diagnose hydraulic issues, check pressures with gauges, and trace loader/3-point problems back to valves or cylinders
  • Follow step-by-step teardown and reassembly on major components like the engine, transmission, and front axle
  • Troubleshoot electrical faults using wiring diagrams, from no-start issues to dead lights and charging problems
  • Adjust linkages, clutches, brakes, and 3-point hitch settings after repairs so the tractor actually works right again
  • Replace seals, bearings, and gaskets with the correct sequences so you don't have to redo the job next weekend

Who this is for

This is for a CT225 owner-operator, farm shop, small contractor, or field tech working on a Bobcat CT225 in the A59B11001-A59B99999 serial range. If you only want basic controls, safety, and daily checks, you want the operator's handbook instead, not this manual.

FAQ

Q: Is this a searchable PDF, and can I read the wiring diagrams clearly?

A: Yes, it's typically a searchable PDF and the wiring diagrams are laid out so you can zoom in and trace circuits.

Q: How do I know if it fits my tractor?

A: Check your serial plate. If your CT225 falls between A59B11001 and A59B99999, this is the right service manual.

Q: Is this the right thing if I'm just doing oil and filter changes?

A: It will cover that, but it's overkill if that's all you need. It's meant for deeper diagnostic and repair work.

Bottom line: If you own or maintain a CT225 in that serial range and plan to do real repairs, this is the manual you want. If you only need operating tips, skip it.
