Front hopper seed drill eases sowing pressure
Austrian tillage and seed drill manufacturer Pöttinger has expanded its range of Aerosem pneumatic seed drills, with the addition of 4 metre and 5 metre folding versions units with a front hopper.
The rake offers a working width of 7.7 to 8.4 metres. Replacing the conventional jockey wheels, Flowtast creates a larger area of contact to improve load-bearing capacity on wet, peaty soils, it says.
Working in conjunction with a hydraulic cylinder to alleviates the weight of the TOP 842 C rotor unit, results in a low ground pressure of about 200kg, protects soil and the glide bar as well as wear and tear on the machine’s frame.
Pöttinger engineers tested various materials and selected a special plastic (PE 1000) for this application.
It says this synthetic material possesses an enormous resistance to wear and abrasion. Each glide bar consists of five individually exchangeable 15mm thick plates. To provide perfect ground tracking and tine guidance, the glide bar is installed close to the tines. It tracks the ground along the full raking length of the tine arc. The sickle shape bar also offers the best gliding properties during sideways movements.

First presented at Agritechnica 2019 in Hanover, Germany last year, the option is said to take over when wheeled assemblies reach their limits, for example, on wet, peaty soils with deep wheel marks, or when working with whole crop forage in fields where the sward does not provide full surface cover.
