''On grip'' tines

The narrow TineTeC coulters of the Cayena are arranged “on grip” and pull themselves automatically into the soil. As the machine is supported via the tractor’s lower links and the wedge ring tyre roller in the rear, the downward pull of the tines is limited. In this way a permanent, even placement depth of the seed, irrespective of the fill level of the seed tank is ensured. The two half-side setting elements allow a central, quick and safe adjustment of the sowing depth.

Narrow and hard

Thanks to their extremely narrow shape the hard metal armoured coulters of the Cayena easily penetrate the soil and move only a little soil – minimising the loss of soil moisture when sowing. The narrow coulter shape offers additional decisive advantages: The pulling power requirement of the Cayena is low and the wear of the coulters is reduced to a minimum and, in spite of its large working width of 6 metres, the Cayena can be operated with tractors from just 100 kW/136 HP.

Narrow row spacing, spacious clearance

36 tine coulters and 16.6 cm row spacing – in three rows and arranged in an offset to one another on the main frame. The coulters of the Cayena, despite their narrow spacing, allow the easy passage of crop residues and stones.

Overload and stone safety device

Special rubber spring elements optimise the adaptation of the coulters to the ground contours, even on hard ground. They also act as an overload protection and stone release function and allow the tines to give way in three dimensions. The slight vibration of the tines in work frees the coulters of organic matter, without adversely affecting the placement quality of the seed.

Blockage-free – even where large amounts of straw prevail

Following the seed placement the exact harrow S covers the seed furrow with loose soil and levels the soil. The covering intensity of the harrow can be also adjusted centrally.
