Ridger Bodies (optional)
The ridger bodies (item 1, fig 16) create the sides of the bed. The ridgers are
positioned by loosening the retaining bolts (item 2, fig 16) and sliding the units along
the tool bar. The height of each ridger is adjusted by loosening the clamp bolts (item
3, fig 16) and then raising or lowering the unit. The pitch of the ridger bodies can be
altered in the same way. To adjust, loosen one bolt and then tighten the other. Which
bolt to tighten and which to loosen depends on the required direction of tilt.
The wings (item 4, fig 16) are adjustable to provide additional control of the soil flow.
To adjust, loosen the retaining bolt (item 5, fig 16) and pull the wings out equally.
Each ridger body is protected by a shear bolt (item 7, fig 16). If the ridger hits an
obstruction the bolt will break allowing the ridger to swing backwards preventing
serious damage to the machine.
If a shear bolt breaks, stop, lift the machine out of work and check for
damage. Reset the ridger and replace the shear bolt. Shear bolts
should be kept tight at all times.
2-Row Front Ridger
The centrally mounted front ridger moves soil from the centre of the bed to the
outsides giving more soil for the openers to work with. Adjustments are the same as
above.
