• The are parts grouped according to the location on the tractor.
• Each group shows an “exploded view” which clearly illustrates each part in its correct  relation to other parts in the illustration.
• You need a parts catalog, it saves you time, money and helps you seem more informed when ordering parts

Also consider purchasing both the operators and service manual for your tractor, if available. The operator’s manual adds all the basic information meant for the end user of the machine, while the service manual will lay out all the procedures for you.
