Grimme launches 4-row self propelled harvester at Agritechnica

Agritechnica 2017 will be the showcase for Grimme’s new 530hp 4-row self-propelled Ventor 4150 potato harvester, complete with a 15t unloading bunker.

The principle of the Ventor’s separation system is based on the SE range of harvesters incorporating digging, de-vining and sieving webs, followed by NB type, pintle web separators. Output on the 4-row harvester is double that of the 2-row alternative, having effectively joined two SE machines together side by side, but without compromising the legal road width requirement.

The technological breakthrough came when an innovative folding mechanism for the two hedgehog webs mounted on each sides of the harvester was incorporated into the design. The Ventor 4150 is the first road legal self-propelled 4-row potato harvester to be fitted with the SE principle of soil separation.

The Ventor includes two patented features in the intake area; with a narrow rubber belt above a rotating torpedo feeding haulm into a cutting knife to prevent a buildup of tops between the lifting units. A unique levelling system after the intake web maintains constant drop height onto the 1st main web; even when the harvester is operating in crab steer.

From the front of the Ventor the intake unit follows the same principle of the SE harvester without the use of a haulm topper. By having no wheels in front of the intake unit it reduces the potential of soil compaction or damage to potatoes.

Speedtronic automatically adjusts the speed of the separating devices based on load sensing; reducing the pressure on the operator. Final crop inspection by up to three people is possible on the picking off table prior to the crop entering the 15t bunker.

Soil compaction and crop damage have been significantly reduced by a crab steer feature and large flotation tyres (front: 900/70 R32, back: 900/60 R38). An inner turning circle of only 6.1m means the Ventor is much more manoeuvrable than a tractor/trailed harvester combination.

A comfortable cab with excellent visibility, combined with the advanced operation of the “ErgoDrive” control arm all help to improve the driver experience. The new 12.1in CCI 1200 operator terminal with new interactive Grimme Digital Interface (GDI), gives the operator a unique overview of the machines operations with all functions at the operators fingertips.

The Visual Protect camera system, AutoPilot system and MemoryControl for the viewing and saving of harvest parameters all come as standard.

A new digital ProCam video surveillance system comprising of two high quality, wide lens cameras and a high resolution monitor gives the driver an unobscured 360° view with no blind spots.
