Preface
This manual enables dealers and distributors to carry out repair and maintenance of the ST-series compact tractors (ST25 / MT225 and related models) quickly and correctly. Step-by-step procedures, matched to the specified special tools, let you finish every task within the times listed in the repair schedule.
Locating information — A contents page leads off each division, listing jobs in numerical order. Follow the operations in sequence unless noted otherwise; text callouts point to the matching items in every illustration, and any required special tool is identified at the exact step where it is used.
Indexing — Each page bears a combined part–section number at the upper outside corner (e.g., 7A-15), making cross-referencing straightforward. Page numbers run consecutively within each subsection, with intentional gaps left for future updates or to signal the start or end of adjacent subsections.
