Both the Varitron 470 model with wheel chassis and the Varitron 470 Platinum Terra Trac version will be equipped with various new innovations.

First up, both versions have more power now boasting a six-cylinder Mercedes Benz diesel engine with 10.7 litre cubic capacity and 460 horsepower (343kW), instead of the previous 435hp (324kW), and including exhaust emission stage V.

A new premium comfort cab has been developed to offer a better operating environment for the driver with optimised noise insulation now optionally available.

Two assistance systems based on Grimme Speedtronic ensure that the harvester can always be driven in the optimum range between performance and crop protection.

Speedtronic-Web increases throughput by an automatic adjustment of the main web speed in relation to working speed and thus improves crop protection.

To avoid any blockages in the ring elevator, its conveying speed is temporarily increased by Speedtronic Elevator in the case that the pressure of the hydraulic system exceeds a defined target value.

A bunker chain greasing system is standard from 2020 on and all Grimme self-propelled harvesters are equipped with a telemetry unit that enables a connection to the customer portal myGRIMME. In combination with the software-module myJobs, the system is able to differentiate automatically between road and field mode and thus can independently generate tasks.

Manually inputting data is no longer necessary which saves valuable working time and minimises potential errors. After completing a job the user receives a detailed overview including all important process parameters, such as fuel consumption, time per working state and weather conditions for example.

Additionally, the lanes are marked in colours according to the work status. The data generated in this way provides the farmer an optimum basis for billing jobs and for possible optimisation of work steps.

If the operator uses certified agricultural software, farm management information system (FMIS), it is possible to connect this software via the data exchange platform agrirouter with myGRIMME. On request, operators can send machine and GPS data from the machine to the FMIS.
