KONGSKILDE DELTA Shear bolt version
The Delta is designed to cultivate in a wide variety of soils. When cultivating soils without large amounts of stones a shear bolt version can be the right choice. When the tine is overloaded the shear bolt snaps, and the tine releases backwards away from the obstacle. The shear bolt may be fitted in either of two holes which provides differing penetration and tine operating angles a real benefit in hard soils.
