Angling Front And Rear Gangs

Changing the angle of front or rear gangs will affect penetration of gangs and mixing and covering of crop residue. By changing the gang angle, the operator can adjust for different soil and trash conditions. Too little total angle between gangs (front and rear gangs set at minimum angle) may leave uncut areas and poor penetration of disk blades. Too much total gang angle (front and rear gangs set at maximum angle) may cause harrow to trail unevenly in hard or soft ground conditions. Also, it may cause the gang to bulldoze so the soil will not flow through the disk blades. The greater the angle, the more aggressively the gang will plow. The ideal situation is for the front and rear gangs to have close to equal amounts of angle so they both plow to the same depth. The front and rear gang carriers both have a series of angle adjusting holes that are located on the frame. Each gang carrier can be adjusted from a minimum of 17.5 degrees to a maximum of 25 degrees - approximately. To change the angle of the front and rear gangs, lower the disk to the ground. Then, remove the gang angle selecting bolts located on opposite sides of each end of the frame. Loosen the gang carrier mounting bolts and the gang carrier pivot bolts on the end of the gang carrier opposite the angle selecting bolts. Slide gang carrier to the desired angle and replace the angle selecting bolts. Make sure to torque securely all bolts that attach the gang carrier to the frame.
