Usually known as the specialists in grass overseeding, Vredo Dodewaard present their new Crop Drill System (CDS) capable of sowing cover crops, grass and arable crops into stubble or grassland.
Launching the slicing double disc system in 1976 which specialises in low soil disturbance the double disc openers are fed via a hydraulically driven fan and metering unit driven by the rear roller. John Campey from JC Machinery commented that the slicing discs are in fact known for no soil disturbance. Available in 4.4m and 5.8m working widths the CDS system costs approximately £7000 on top of the price for the standard overseeder.
The Pneumatic metering system is capable of delivering up to 240kg/ha in stepless segments and can handle all cover crops or arable crops as needed. Delivery is to the standard width of 7.5cm row spacing but via and additional hydraulic system the operator can raise alternate disc sets allowing 15cm row spacing. This not only supports a multitude of crops but also allows higher downforce to be applied to ensure soil moisture is encountered.
Following the cutting discs a slightly offset roller ring ensures each row is closed and a studded roller firms the soil around the seed. The rings of the roller can float ~5cm to allow exact contour following in a variety of conditions or stoney fields.
The Agri Twin Overseeder has received a Silver Innovation award at the 2020 LAMMA show and can be seen on Stand 17.430
