Overview
The Massey Ferguson AgTV 250, 300, 400 and 500 Quad ATV Service Manual provides technical information for maintaining, inspecting, troubleshooting and repairing the covered Massey Ferguson all-terrain vehicles. The documentation includes model-specific specifications, periodic maintenance, petrol engine and transmission repairs, carburettor and fuel systems, lubrication and cooling, electrical wiring, drive axles, suspension, steering, brakes, chassis components and operating controls.
Repair topics include engine and crankcase disassembly, clutch adjustment, carburettor servicing, oil pump pressure testing, differential and axle repairs, ignition and starter diagnostics, and steering and suspension adjustments. The contents below group repeated topics under shared technical headings, while retaining references that are genuinely configuration-specific, including 500 cc automatic transmissions and certain brake, drive and V-belt arrangements.
Notice: The original manual has separate 250/300 cc and 400/500 cc sections. Shared topic labels below are condensed for readability, not an indication that specifications or parts are interchangeable. Confirm the model, drive type and transmission before using a procedure.

Model-Specific Engine and Transmission Service References
The original workshop publication separates general information, maintenance, engine/transmission repairs, electrical service and troubleshooting into 250/300 cc and 400/500 cc model groups. This condensed index removes repeated capacity labels from common subjects; the manual retains the individual specifications and procedures for each model group.
Select the installed drivetrain before using the repair instructions. In particular, the 500 cc automatic transmission has dedicated removal and crankcase procedures, the 400 cc 2×4 model has a separate left-side component installation reference, and brake, clutch and V-belt information varies by transmission arrangement.
