Key changes to the 2021 John Deere 4-Series Self-Propelled Sprayers include roll out of the CommandDrive all-wheel drive system to more models and additional enhancements to the optical carbon fibre boom

John Deere is making a push for more market share with the 4-Series self-propelled sprayer range available to order now.

Deere intends to entice buyers by offering updates aimed at greater efficiency from these 2021 models with improvements to operational traction.

While also offering operators a much quieter ride than previous models and easier management of the booms by adding a carbon fibre options.

Further key changes to the model year 2021 line-up include the roll out of John Deere’s CommandDrive all-wheel drive system to the R4038 and R4030 models – already available on R4045 and R4060.

CommandDrive is designed to help cover difficult ground more efficiently as it allows operators to travel over hills, wet spots, and soft ground without added wastage.

This is achieved through an intelligent powertrain that uses a single hydrostatic pump to power all four variable-displacement wheel motors.

For instance, if one or more wheels lose traction, the system adjusts to slow the slipping wheel and directs more flow to the other wheels with traction, to keep the sprayer moving.

In addition, CommandDrive works in tandem with the engine and entire sprayer system to automatically increase RPMs when more power is needed and to maintain proper spraying.

The Auto Mode setting allows operators to maintain selected ground speed and application rate at lower engine RPMs and automatically reduces the engine’s RPM to 900 when the machine is stopped, thereby reducing fuel consumption by up to 20%.

Another option worth considering is ExactApply nozzle application

It’s at the business end where growers will notice the greatest cost savings from John Deere’s 4-Series Self-Propelled Sprayers as the optional T6 and T7 suspension rope booms are designed to run across difficult terrain and still be able to reduce input costs

Deere engineers, sweating on a way to bring precision farming technology and cost control to the forefront, have adopted this nozzle design as a way to minimise overlap.

It works around controlling product application with individual nozzles rather than the whole section.

While on the subject of getting everything you want, the AutoTrac Vision and RowSense options offer a higher degree of accuracy for in-row crop applications using a camera or paddles.

But it’s at the application end where Deere engineers have made the most progress.

Take note of the upgrades that come with the optional carbon fibre T6 and T7 suspension rope design.

There is an additional breakaway bumper for more stability, with a breakaway strap wear plate and solenoid design to improve fold functionality.
