Holmer does not normally implement manufacturer, and the project to develop its first slurry injector started in 2021. Following successful tests this season, the camera steering system on the prototype, which was attached behind the Terra Variant 435, comes from Claas, but the rest of the 7.5m-wide unit, which is designed for applying slurry to 10 rows of maize, was developed by Holmer.
Claimed as a new approach, slurry is injected either side of the row at depths from 2.0-4.0cm. Any slurry on the surface is covered by a rear share. The company says the technique has already been successfully tested in 65cm-high crops.
Main features include the compact design of the sliding frame to keep the centre of gravity as close to the vehicle as possible, and the width of each unit is easily changed using a lever (min row spacing in 45cm).
The plan is to test some of the five pre-production units in Germany (and other Euro countries) next season in sugar beet.
The first commercial units are planned for 2024, and the injector will be available for fitting to other brands of self-propelled machines.
