Tillage disc arm drift control

A ground engaging tool connectable to a mounting bar on a cultivator, the ground engaging tool comprising:

• a bottom bracket;
• a cap bracket connectable to the bottom bracket, for attachment to the mounting bar, the cap bracket comprising:
• a first member having a first side and a second side;
• a second member having a first side and a second side, the second member joined at the second side to the second side of the first member;
• a peak formed where the second side of the first member is joined at the second side of the second member;
• and
• a first extended portion extending laterally from a first end of the cap bracket at the peak so that the first extended portion at the peak extends further laterally than the first end of the cap bracket at the first side of the cap bracket;
• an arm attached at a top end to the bottom bracket;
• and
• a ground working tool attached to a bottom end of the arm.

A cap bracket for connecting a ground engaging tool to a mounting bar of a cultivator, the cap bracket comprising:

• a first member having a first side and a second side;
• a second member having a first side and a second side, the second member joined at the second side to the second side of the first member;
• a peak formed where the second side of the first member is joined at the second side of the second member;
• and
• a first extended portion extending laterally from a first end of the cap bracket at the peak so that the first extended portion at the peak extends further laterally than the first end of the cap bracket at the first side of the cap bracket.

A spacer for positioning between an adjacent pair of cap brackets, each cap bracket used to attach a ground engaging tool to a cultivator, the spacer comprising:

• a first connection flange;
• a second connection flange;
• and
• a spacer member extending upwards from the first connection flange and the second connection flange to define a contact surface positionable between the adjacent pair of cap brackets,
• wherein each cap bracket, in the adjacent pair of cap brackets, is attached to a bottom bracket that is attached to a ground engaging tool by an arm.
