Earlier this week we ran a story about the Nexat gantry system developed by German firm Kalverkamp Innovations. Powered by a pair of 550hp Liebherr engines, the striking vehicle carries a number of specially-made Väderstad cultivators, drills and planters.
The Swedish company has not been a part of the full Kalverkamp journey which started in 2017, but has been a partner for the last two years, explains Fredrik Gustafsson, Väderstad director product management.
The Nexat system is designed to be adaptable between 6.0m and 24.0m, but the existing Väderstad kit currently fitted to the two test vehicles in the Ukraine are all 14.0m wide.
“This is the planned width for the first commercial units,” comments Mr Gustafsson. “Going forward we will adopt the widths of our modules according to the system.”
Carrying the modules rather than pulling them has allowed the company to develop a simpler and lighter main frame. “The machines are all based on existing Väderstad kit but in other combinations which doesn’t necessarily translate to an existing product family.”
One of the fundamental ideas of the Nexat system is that there should be no other vehicles in the field, which explains the monster 32.0m³ grain tank of the NexCo combine harvester. We are intrigued to know whether Väderstad has been able to fit a similarly large seed hopper to allow the vehicle to run for longer intervals between a refill.
“Our focus is on flexibility to enable the system to carry different seed or fertiliser at the same time in separate hoppers. However, we have tried to give the system as much capacity as possible. Total hopper capacity is currently 20.0m³.”
