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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003eBuilt for the John Deere 4940 Self-Propelled Sprayer\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan style=\"color: rgb(43, 0, 255);\"\u003eThe 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.
