Importance of good chain setup
Operational
It is imperative that the correct chain tension is maintained. Only through correct tension can
a smooth and level finish be achieved in field working.
Loose chains lead to :
• Uneven performance across the width of the machine
• Uneven weed control
• Unsatisfactory incorporation
• Ineffective levelling
• Accelerated or premature chain link wear (not covered by warranty)
• Chains failing to engage with transport locator’s when folded
• Machine damage when folding or unfolding
• Uneven field surface with ridges and furrows being created.
A correctly adjusted machine will not cause this phenomenon.
The framework should be horizontal when set on level ground. ie parallel to the ground.
Fine adjustments should be made using the adjustor chains at each bearing mount plate.

Once the frame is level tighten the lock nut (Fig 21.) on the drawbar ratchet (Fig 20.). This sets the draw
bar height correctly for your tractor.
