The launch of the next generation 2 row Self Propelled Potato Harvesters by Grimme sees a new era for the company. Varitron 270 Platinum is the first to be launched in the latest range.
It starts with the new high torque 6-cylinder Mercedes Benz engine with 7.7 l capacity and 354 HP which replaces the old 326 HP. The engine runs at 1,300 rpm during road travel and 1,500 rpm during digging.
Fuel consumption is significantly reduced with the new engine due to the new engine speeds. The latest exhaust technology is also included in this upgrade.
Everything in view and under control is the motto of the ErgoDrive concept in the comfortable drivers cab with panorama view. The new ergonomically designed control desk integrated into the driver’s seat immediately catches your attention. This has been designed especially for the complex demand of selfpropelled potato and beet harvesters.
Up to 77 different functions can be programmed into the armrest and of course via the joystick, rotary or touch keys to avoid searching on the terminal. Quick software programming via the control panel is possible. With Clean Control, settings and adjustments made by the driver can be saved and then recalled easily when in the same or similar digging conditions. A total of 16 storage spaces are available with Clean Control. This function can keep individual values even when changing operators.
Two modern control terminals and two professional video monitors ensure a perfect overview. With up to 8 cameras to ensure nothing remains unobserved.
Visual Protect automatically switches the camera on, where a critical situation has been noticed (risk of a separator blockage e.g.), so the driver can react and prevent the blockage.
Turning night into day with the 6 standard LED headlights, which create a great panorama view and automatically switch-on while driving backwards for example.
The machine hydraulics have been radically changed. The whole hydraulic pipe layout is in a much eater understand-able way and makes fault finding much easier. As only the required components and pipe work are fitted for increased efficiency.
Also new is the track tensioning via the machine hydraulics of the VARITRON. Previously an external system was required (tractor hydraulics e.g.), now by switching the ball valve the tensioning is activated.
The new profiled carrier rollers, designed by Grimme, in the rubber track ensures smooth running under strong conditions without blockages.
The haulm feed-in roller brackets have been redesigned to allow a quick, almost tool-free maintenance when changing webs.
The new telescoping rear axle is a real all-rounder. For the first time a machine width under 3.5 m is achievable in con-junction with narrow wheels (option) and a row width of 75 cm. For digging it is possible to extend the axle by an impressive 550 mm which ensures the highest driving stability.
The inner turning circle of only 5.3 m generates the most manoeuvrable 2-row self-propelled harvester on the market.
Corrosion-free GFK bars are fitted to the 1.1 m wide picking web. Soil rarely sticks to the web and it is also
about 80 % lighter than traditional webs.
The new reversing system is unique to the VARITRON Platinum. The intake web as well as the 1st and 2nd main web are independently reversible to minimize the risk of block-ages under all digging conditions. And if a web gets blocked, it can easily be reversed without damaging the crop or need to get off the machine.
Various separators are available for the VARITRON series. Beside the fine haulm elevator, Grimme offers a Roller Separator or MultiSep and is the only manufacturer that offers a VarioRS, double MultiSep or the combination of a Roller Separator and VarioRS or MultiSep.
The 7 tonne Nonstop Bunker is unique to the market and applied for a patent. The whole time the effective capacity is in use thanks to the rotating bunker web and furthermore it is significantly gentler than traditional systems. When stationary it has an unloading time of only 45 seconds. The bunker head is hydraulically lower able in 3 steps and there-fore ensures extremely low drop heights during unloading. The maximum unloading height is 4.2 meter and the lowest position is only 1.4 meter. The user is talking about an in-creased output of 35 % compared to traditional bunker systems.
OptiBags with high resistant polyurethane are available as an option for the ring elevator. This creates an additional cleaning area and ensures gentle crop transport at the same time. If necessary it is possible to exchange a single pocket rather than the whole web.
