    OPTIONAL EQUIPMENT 1. BOGIE AXLE KIT (2 x No 113 6180) ) (standard equipment on GA 7301 USA) This equipment is recommended for improved floatation when operating on irregular grounds. It helps stabilising the machine at high speed thereby reducing the load placed on structural components.
  • Page 30 2. 3D - SUSPENSION KIT (No. 114 6400) The 3D - suspension kit provides an additional degree of freedom to the rotors. Under the support of a third wheel, the rotor pitch angle is adapted to the ondulations of the terrain. The result is a better raking quality and greater crop yields when working in uneven conditions.
