Grimme unveils 4-row self propelled harvester at Agritechnica

A new 530hp four-row self-propelled potato harvester – complete with a 15t unloading bunker – will be showcased at this month’s Agritechnica show at Hannover, Germany.

Grimme’s Ventor 4150 four-row harvester will be the company’s star exhibit at the show from 12-18 November. Output is twice that of the two-row alternative, having effectively joined two
SE machines together without compromising the legal road width.

The principle of the Ventor separation system is based on the SE range of harvesters. It incorporates digging, de-vining and sieving webs, followed by NB type, pintle web separators. The Ventor is the first road legal self-propelled four-row potato harvester to be fitted with the system.

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. It includes two patented features in the intake area.

Levelling system

A narrow rubber belt above a rotating torpedo feeds 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 first 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.

Crab steer

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

A comfortable cab with excellent visibility and control arm improve the driver experience. The new 12.1in CCI 1200 operator terminal with interactive Grimme Digital Interface, gives an overview of operations with all functions at their fingertips.

The Visual Protect camera system, AutoPilot system and MemoryControl for harvest parameters all come as standard. A digital video surveillance system comprising two wide lens cameras and a high resolution monitor provides an unobscured 360° view with no blind spots.
