Download 4940 Self-Propelled Sprayer Operation Maintenance & Diagnostic Service Manual TM113519 PDF 

The John Deere 4940 Self-Propelled Sprayer Operation, Maintenance & Diagnostic Test Service Manual TM113519 is the complete factory operation, maintenance, and diagnostic test service reference for the John Deere 4940 Self-Propelled Sprayer — 2220 pages of detailed factory operating procedures, complete maintenance schedules, structured diagnostic test procedures, full electrical wiring diagrams, hydraulic schematics, advanced electronic control system diagnostic procedures, sprayer system diagnostic test procedures, AutoTrac guidance system diagnostic procedures, Section Control diagnostic tests, application system diagnostic procedures, and comprehensive troubleshooting guidance covering every system on the 4940 Self-Propelled Sprayer in a single authoritative factory document.

Whether the task is learning correct 4940 sprayer operation for row crop, broadacre, or specialty crop applications, understanding all 4940 instrument panel warnings and correct operator responses, performing a complete scheduled machine inspection and service, performing structured factory diagnostic tests on the 4940 PowerTech engine management system, diagnosing a hydraulic drive system fault using factory test procedures, testing the 4940 multi-ECU electronic control system for fault codes and sensor failures, performing factory-level diagnostic testing on the boom hydraulic system, testing the 4940 application system including pump, flow meter, and nozzle control components, diagnosing AutoTrac guidance system faults using factory test procedures, testing Section Control and variable rate application system components, performing factory diagnostic tests on the 4940 sprayer boom suspension system, testing all chassis and drivetrain systems for correct performance, or following the complete factory maintenance schedule to keep the 4940 in reliable working condition through demanding spraying seasons — TM113519 is the original factory document that covers every aspect of correct operation, complete maintenance, and factory-level diagnostic testing for the 4940 Self-Propelled Sprayer across 2220 comprehensive pages.

Spraying season is one of the most time-critical and agronomically sensitive periods in any broadacre farming operation. Application accuracy, correct boom height management, correct nozzle performance, correct product rate application, correct guidance performance, and correct machine reliability through demanding high-acreage spraying seasons directly determine application quality, crop protection effectiveness, input cost management, and ultimately crop yield potential. A self-propelled sprayer that is incorrectly calibrated, insufficiently maintained, or experiencing undiagnosed system faults applies product incorrectly, wastes expensive agricultural chemicals, creates crop damage from skips or overlaps, and fails at the most critical times. TM113519 provides the complete factory technical knowledge required to operate, maintain, and diagnose every system on the 4940 correctly through every spraying season.

Built for the John Deere 4940 Self-Propelled Sprayer

The John Deere 4940 Self-Propelled Sprayer is a large-frame high-clearance self-propelled sprayer built for high-capacity, precision application of herbicides, fungicides, insecticides, liquid fertilizers, and other agricultural chemicals across large broadacre row crop farming operations. The 4940 is designed to deliver maximum field capacity — covering the maximum number of acres per day — while maintaining the application precision required for effective crop protection and correct input cost management across every acre sprayed.

The 4940 is powered by a John Deere PowerTech diesel engine delivering the power required for demanding spraying conditions including fully loaded tank operation on hilly terrain, high-speed transport between fields, and continuous boom actuation during difficult field conditions. The hydrostatic ground drive system provides smooth, infinitely variable ground speed control for precise travel speed management during spraying, correct speed-based application rate control, and efficient field maneuvering. The large-frame high-clearance chassis provides the ground clearance required to spray over established row crops at advanced growth stages without crop damage.
