Hoe-Type Fertilizer Furrow Opener

CQ289210-UN-24JAN11

Hoe-type furrow opener necessarily requires using the cutter disk. The furrow opener can be mounted in one of two positions. One position is close to the cutter disk and the other is further away. These different mounting positions can be very useful in different operating conditions, since they permit that the hoes can be offset, thereby improving the flow of straw between them.

Adjusting Angle of Attack (Y) between Hoe and Ground

1. Remove bolt (A).
2. Loosen bolt (B).
3. Align hole (C) of hoe shaft with bolt hole and insert bolt (A).
4. Tighten bolts (A and B).

IMPORTANT: A lesser angle of attack (Y) implies greater penetration capacity and less force is needed for traction.

A greater angle of attack (Y) implies less soil turn over.

These observations may differ due to local ground conditions and they should be verified in practice to determine the best operating position.

NOTE: The bolt works as a shear bolt, i.e. it will break if the hoe encounters an obstacle that may damage it. If this occurs replace bolt by another of class M10, grade 8.8.

CQ292514-UN-25JAN12

When the hoe-type furrow opener is adjusted to the greater angle of attack (Y), there is a difference of (X) in furrow depth.

To correct this difference, use depth adjustment bolt (A) or adjust the position by means of bolts (B).
