Deere Debuts New R4045 Sprayer

Deere R4045 Sprayer With the introduction of the R4045 Sprayer, John Deere is adding a higher horsepower, large capacity self-propelled sprayer to the lineup of 4 Series sprayers introduced in 2013. The R4045, which replaces the company’s 4940 Sprayer, offers the high application rates, productive spray speeds, and all the technology and comfort that ag service providers and large producers need to cover large fields quickly and efficiently.

Dave Mulder, product line manager for John Deere application equipment, says the new sprayer offers the performance, productivity and versatility that farmers and ag service providers need in a rugged, fully-integrated, three-season machine. “The R4045 Sprayer was designed with the durability to handle challenging field conditions and accurately apply liquid product and dry nutrients as quickly as possible while providing the uptime, comfort and control operators demand. It’s all engineered and built into this machine.”

The new R4045 Sprayer features a 346 horsepower Final Tier 4 PowerTech PSS 9.0L engine with four-wheel hydrostatic drive that can operate at 25 MPH spraying/spreading and 35 MPH in transport. For liquid applications, it comes with a 1,200-gallon solution tank and option of 90-, 100-, or 120-foot dual swing-link suspension, flat-fold booms that can apply up to 230 gallons per minute with a high-flow pump and dual flow meter.

The industry’s newest Class 4 sprayer can easily be converted to a dry nutrient applicator by installing a high-capacity 200- or 300-cubic foot New Leader dry spinner spreader, increasing the use and versatility of the machines.

The R4045 shares a similar frame and chassis design, as well as the standard and premium CommandView II PLUS cab options, as its R4030 and R4038 family members. This includes a more spacious cab with more glass for greater visibility, the high-backed ComfortCommand Seat and redesigned CommandARM with integrated GreenStar 3 CommandCenter display for more comfortable, finger-tip control of all machine operations. The cruise control feature allows the system to automatically control the vehicle to the operator’s target speed when the operator sets the engine speed and hydro handle at maximum positions.

Mulder says many other features have been built in to the R4045 to make loading and applying product even faster and more precise. “Our exclusive Load Command system can fill the 1,200-gallon tank in as little as three minutes, and the factory-installed front fill option makes loading the machines much easier and convenient with 3-inch Quick Fill couplings,” he adds.

The R4045 Sprayer equipped with the Solution Command System comes with the industry exclusive Target Fill feature, which allows the operator to input the desired fill level (min. 150 gallons) using the numeric keypad. Target Fill consists of a tank level sensor inside the tank, the appropriate software and a micro display that shows the actual volume in the solution tank during the filling process.

Other optional features of the R4045 include the Direct Injection system that promotes quicker changeovers and faster cleanouts, and helps lower the risk of using multiple products. Standard end cap aspirators at the end of each spray section reduce nozzle turn-off time and the boom air purge system is available to help purge out additional product during change over. The new tri-directional breakaway tip sections and full-boom breakaway features help protect the booms, and the number of boom sections has been increased to improve spray resolution by up to 33%.

“Operators can quickly adjust boom height from 19 inches to 92 inches or add BoomTrac Pro for automatic boom-height control,” notes Mulder. “Because the chassis sits on a dual strut independent wheel air-ride suspension, operators will enjoy a smooth, stable ride at higher speeds, and auto air spring leveling keeps the chassis level at all times, including on uneven terrain and as the spray tank empties.”

The GreenStar 3 2630 Display features increased memory, a touch-screen interface, video capabilities and is ISOBUS compatible. It comes loaded with Field Documentation, Map-Based Prescriptions, On-Screen Mapping and other applications.

Other integrated technologies that further enhance productivity include AutoTrac, John Deere Section Control, John Deere Mobile Weather and AgLogic. JDLink is available and enables Remote Display Access, Service ADVISOR Remote and Wireless Data Transfer. These are all part of the John Deere FarmSight experience available through local dealers to help customers more efficiently utilize their machines.

“The new R4045 Sprayer provides the latest in application technology that’s ideal for ag service providers and large producers needing a high capacity, high performance applicator,” Mulder says. “These machines are designed to load faster, cover more acres in less time and apply material more accurately while making it easier and more comfortable for the operator.”
