Initially, these tractors are shipped with four manuals – the Tractor Owner's Manual, the Tractor Parts Manual, the Engine Owner's Manual, and the Engine Parts Manual. You really need all four manuals to have the complete information necessary to work on one knowledgeably. All the torque specs for the engine are in the engine manual, not the tractor manual, for instance. And so on. Dealers like Tommy at Affordable can supply you with all the necessary manuals if you tell them both the particular engine in your tractor and the tractor model number.
