How a Repair Looks on FieldTech

Why FieldTech exists

Service manuals tell you how a machine is supposed to work. They don't tell you what actually broke last Tuesday on a 336F with 8,400 hours in 104°F heat. That knowledge lives in technicians' heads and gets lost when they retire, switch shops, or move on.

We're building a permanent, searchable, verified record of those repairs — owned by the community that creates it. Every case you post makes the next technician faster.
