The John Deere Sprayer 4045 is a self‑propelled field sprayer from the 4‑Series for crop protection. It was built from 2012 to 2014 and belongs to the John Deere Sprayer product line. The machine is equipped with an inline six‑cylinder engine of 9,001.4 cm³ displacement, rated at 258 kW at 2,200 rpm and delivering a maximum torque of 517 N·m at 1,550 rpm. It runs on 7‑15 ppm Ultra Low Sulfur Diesel, uses direct injection, a turbocharger with wastegate and air‑cooled charge air, and meets the Interim Tier 4 emissions stage. Fuel tank capacity is 586.7 l, turning radius 9,200 mm, and the spray system comprises 13 sections.
A power output of 258 kW enables rapid coverage of large fields and drives high‑capacity pumps for uniform spray distribution. The high torque at low rpm assists starting under full load, while the large tank extends operating time. The 9,200 mm turning radius facilitates maneuvering in narrow rows, and the 13 sections allow precise dosing across different crops.
Within the Sprayer range the 4045 ranks 1 of 7 models with 258 kW. The next smaller model 4930 provides 242.4 kW. The overall power span of the series is from 79 to 258 kW.
John Deere Sprayer: self-propelled field sprayers of the 4 Series from 4045 to 6700 with PowerTech diesel engines, 79 to 258 kW, four- to six-cylinder
John Deere builds self-propelled field sprayers for crop protection in the 4 Series, which unlike trailed or mounted sprayers carry their own drivetrain, their own chassis and usually a raised cab for working in growing crops; the register lists here the types 4045, 4720, 4730, 4830, 4920, 4930 and the older 6700. The machines are powered by John Deere's own PowerTech diesel engine range, including the 6068T; the engines drive the travel hydraulics as well as the pumps for the spray system.

The register lists here 7 versions with 79 to 258 kW from four- to six-cylinder engines of 4,523 to 9,029 cm³ displacement.
Self-propelled sprayers such as the 4 Series are common in large-scale arable farming in North America and Europe, where compared with trailed sprayers they offer higher area output, greater ground clearance for tall crops and more precise boom control; John Deere competes here chiefly with Case IH and Hagie.
For a used purchase of these sprayers, check the condition of the boom and nozzles, the tightness of the spray pump and lines, the condition of the tyres or track-width adjustment, the calibration of the metering system, and the operating hours and service condition of the PowerTech engine; spare parts run through the John Deere dealer network. On the older 6700 versions, it is also worth checking the availability of specific parts for boom control and metering, which have become increasingly scarce.
