The Bracke S35.a attaches to a scarifier rig and is used to sow in conjunction with scarification.
The S35.a can be attached to the T26.b , T28.a, T35 or M24.a, M36.b and even some older two- and three-row scarifiers T21.a, T26a, M26.a, M36.a
The seeder senses the scarifier rig's forward speed and regulates the seed feed accordingly.
The seeder can also be synchronized with the scarifier, so that only scarified soil is sown.
