Description
John Deere GX Series Technical Manual for the GX255, GX325, GX335 and GX345 garden tractors. Identified by publication number TM1973, this factory service technical manual provides workshop information for servicing, fault diagnosis and repair across the model range.
The publication is intended for professional technicians, machinery workshops and experienced owners carrying out structured maintenance or repair work. It brings together specifications, machine information and model-specific technical sections covering the engines, electrical equipment, hydrostatic power train, hydraulics, steering and brakes.
Engine coverage is divided according to tractor model and installed engine. This distinction is important when identifying specifications, service information and repair procedures, particularly where similar tractors use different Kawasaki engine types.
