AGCO ST28A, ST33A Compact Tractor Service Manual

The bodywork photographs show the hood supports, front grille connections and fittings encountered before reaching the components below. Air-cleaner instructions distinguish inspection from removal, and the standard gearbox cutaway labels the main and range-drive parts. These are configuration-specific books: a mechanical gear arrangement should not be used as a substitute for the hydrostatic transmission procedure.

Systems & Components Covered

• Access and separation work: Hood and grille removal, body fittings and the disassembly sections used to reach major components.
• Engine accessories: Air-cleaner removal, inspection and related external engine-equipment information.
• Standard drivetrain: Clutch, main and range transmission, rear transmission and axle-housing sections in the standard book.
• Hydrostatic drive: The hydrostatic transmission section and its associated mechanical transmission information.
• Axles, steering and hydraulics: Front axle, rear housing, steering and hydraulic-system chapters for the relevant version.
• Electrical and maintenance references: Electrical equipment and the lubrication or maintenance information identified in each book.

The Digital Workshop Advantage

The labelled gearbox cross-section makes it possible to follow the relationship between a shaft and the gears around it. Body-access photographs use a different set of callouts for clips, supports and wiring connections. Reading those drawings within their own transmission edition avoids combining instructions from two differently arranged machines.
