Adjusting Front Fold Cable - Hardi EAGLE 3PT Boom Operator's Manual

6.5 Adjusting Front Fold Cable

The performance of the EAGLE 3 Point Boom, while spraying, depends
greatly on the front fold cable adjustment. A correctly adjusted cable will
also control the movement of the outer wing section.
WARNING: THE REAR CABLE CAN SNAP AND INJURE YOU OR
1. Unfold boom into operating position.
2. Shut the tractor off.
3. Check the security of turnbuckle anchors to the hinge.
3. Slide a straight edge down the underside of the intermediate boom
section until it just contacts the front cable.
4. Suspend a 10lb (4.5kg) weight from the straight edge-to-cable contact
point and check deflection by measuring the distance from the
straightedge to the cable. Cable should deflect .50-.75 in. (13-20mm).
5. Loosen jam nuts (A)(Fig. 15) on the turnbuckle assembly and adjust
turnbuckle (B)(Fig. 15) for proper cable deflection.
6. Tighten jam nuts (A)(Fig. 15) and remove weight.
IMPORTANT: Check boom alignment again. If front cable was tight-
ened, the wing assembly will move forward; or if loosened, wing will
move rearward. Adjust fold cylinder (if necessary) as described in
Aligning Wing Assemblies, (Section 6.3).
