The proven haulm topper, HT 400, is especially suitable for long, tough haulm in potato crops.

For season 2021, Grimme’s four-row self-propelled potato harvester VENTOR 4150 will be equipped with some new practical features.


The manufacturer of agricultural machinery recently announced that its VENTOR 4150 can now be optionally equipped with the HT 400 haulm topper, which is especially suitable for extremely high quantities of long, tough potato haulm. In addition to a significant increase in throughput, haulm topping prior to the harvesting process reduces the risk of losses on the deviner web. The potato haulm is widely distributed on the already cleared area by use of a cross conveyor and an integrated haulm spreader. Automatic depth control is monitored via skids on the potato rows and can be conveniently adjusted from the operator terminal in the drivers cab. For road transport, the HT 400 is hydraulically folded over the intake unit.

Reduced soil sticking
For use on heavy soils, highly wear-resistant plastic share blades can be used, which helps reduces soil adhesion and keeps wear to a minimum. The share blades are made of highly wear-resistant plastic and reduce soil buildup in severe, sticky conditions.

Further stone protection on the share blades 
In addition to the familiar shear off bolts on the share blades and the share frame, the share arms can now also be protected against overload by a shear off bolt. The required shear force can be varied with three holes for the positioning screws.

Speedtronic-web
The optionally available “Speedtronic-Web” automatically adjusts the speeds of the main webs, including the deviner web, in relation to the forward speed of the harvester. The system is particularly characterized by an increase in driver relief and the maximization of crop protection.

Automatic cleaning of the separators
The feature called “Turbo Clean” facilitates the cleaning operation of certain webs and separators. The drives of the webs and separators are step by step driven with maximum speed so that self-cleaning is achieved. Turbo Clean can be activated manually at the push of a button or automatically at the end of the field.

The VENTOR 4150 can be optionally equipped with large-volume tyres “MICHELIN CEREXBIB 2” which have a dimension of VF 900/60 R38. Thanks to MICHELIN UltraFlex technology, these tyres can be run at low inflation pressures, significantly increasing the ground contact area for optimum ground protection and operational safety.

Fast unloading
The drive of the bunker unloading conveyor was revised in such a way that the unloading time of the 15-ton bunker could be reduced from 90 to just 60 seconds.

Mapping of crop gross weight and digital capturing of harvest masses
For the documentation of harvest masses, the VENTOR 4150 can be equipped with an integrated system for mass mapping. Based on this data, a yield map can be created that visualizes zones of high and low yield. With the help of a Farm Management Information System (FMIS), a map for the site-specific application of i.e. fertilizer, pesticides or seed can be derived from this yield map. All measured values can be stored in ISO-XML format and transmitted using a USB stick or the manufacturer-independent data exchange platform “agrirouter”.
