Fitting the Sponge Bar
Assemblies
Locate the plain end of the sponge bar within the spring-loaded bearing on the side of
the drill under the seed/fertilizer hoppers applying sufficient even pressure along the
bar.
Depress the spring in the bearing block so the collar on the motor end of the roller bar
clears the end of the slotted driven shaft on the other end of the drill.
Release the pressure on the bar, allowing the collar to engage with the drive shaft.
Rotate the sponge bar assembly until the roll pin locates in the slot on the drive shaft.
In this position, all the sponges should be in line with the hopper openings.
Check that all sponges are secure on the shaft.
Always fit the furthest away sponge bar first and make sure that the sponge bar located
correctly at both ends.
They should align with the hopper openings. When the second bar is fitted, align the sponges
with each other. If adjustment is needed, loosen with a 3mm Allen key and align making sure
both sponge bars are fully engaged with the motor end drive.
Bolted Connections
All bolts and grub screws should be re-tightened after the first day or 10 ha of use. Thereafter
the tyne and tip bolts should be checked at regular intervals (i.e. every 50 - 100 ha). Nyloc
nuts should be replaced or a spring washer added after they have been removed more than
once.
