Description
John Deere 6100 6500 6600 Sprayer Service Manual is the factory Service Technical Manual TM1511 for the John Deere 6100, 6500 and 6600 self-propelled sprayers. It provides detailed repair information together with system operation, diagnostic procedures, tests and adjustments for the principal mechanical, hydraulic, electrical and spraying systems fitted to these machines.
This publication is intended for agricultural machinery technicians, sprayer specialists and professional workshops carrying out fault diagnosis, component repair and scheduled maintenance. Its organisation separates component repair sections from operation-and-test material, allowing technicians to study system function before performing checks, adjustments or repairs.
Coverage begins with safety, general specifications, fuels and lubricants. The technical sections then address the engine, fuel and air systems, hydrostatic powertrain, steering, brakes, hydraulics, solution spray equipment and operator’s station. Electrical diagrams, theory of operation and model-specific control-system information are also included.

Subjects covered include:
- Engine removal and installation
- Engine cooling-system repair
- Air intake and exhaust components
- Diesel fuel-system service
- Engine diagnostic information
- Fuel and air system diagnostic information
- General specifications, fuels and lubricants
HYDROSTATIC POWERTRAIN, STEERING AND BRAKES
The powertrain material covers the removal, installation and repair of hydrostatic drive components and power wheels. Steering and brake sections combine component repair with operational checks, system tests, adjustments and theory of operation.

JOHN DEERE 6100 6500 6600 SPRAYER SERVICE MANUAL TESTING AND ADJUSTMENT
TM1511 contains dedicated operation, test and adjustment sections for the powertrain, steering and brakes, hydraulic system, foam marker and operator’s station. These sections include system operational checks, diagnostic information, test procedures, adjustments and theory of operation. The electrical section also provides diagrams and system-specific diagnostic material for tracing control and circuit faults.
TROUBLESHOOTING AND REPAIR
Diagnostic information is arranged by system so technicians can relate symptoms and operational checks to the relevant repair section. The combination of theory, testing and component repair makes the manual suitable for investigating electrical, hydraulic, hydrostatic drive, steering, braking, spray-control and cab-system faults. A section covering dealer-fabricated tools is also included.
