Instruction set for operating 9 Tyne cultivator is secondary tillage equipment most commonly used in India for field preparation. It essentially has tynes with reversible high carbon showel points at the end arranged in two rows on a sturdy steel frame. The front row has five tynes and the rear row has 4 tynes and it is ideally suited for 35 h.p. Tractors of all makes and types with cat ii linkage. Depth of operation is controlled by tractor hydraulic.

1. Hitching the cultivator to tractor
A) Attach the cultivator to the tractor by aligning the holes of the lower arm with the pins attached on either side of the cultivator and the pushing the holes of the lower arm of the tractor in to the pins of the cultivator. Lock the free end of the pins with lynch pins.
B) Align the adjustable screw top link of the tractor with the holes on the upper edge of the three point linkage of the cultivator by placing the top link in between the two flats of the three point linkage of cultivator and then lock the same by means of the pin provided with the top link and lock the free end of the pin with lynch pin.
C) Tighten the top link to the extent that the three point linkage of the cultivator is perpendicular to the ground for normal operation.

2. Angle of penetration
The angle of penetration / pitch of showel points can be varied very easily by adjusting the top link. Tightening the top link increases the angle of penetration resulting in deeper penetration while loosening the top link has reverse effect.

Maintenance tips
1) Ensure proper tightening of all nut bolts with periodical checks as per the usage conditions.
2) Ensure usage of lynch pins to lock the free ends of the locking pins.
