raised area behind the centre of the disc harrow then raise up the threaded
rods at the front (A) or lower the threaded rods at the back (B). The setting
depends upon soil type, planting depth, the moisture of the soil, and the
forward speed.
There are also 2 points at the end of each side where fine adjustments can be
made to the height of the disc chains. (A) refers to adjustment of the front
chain, (B) refers to adjustment of the back chain.

This adjustment option is intended for use once the disc harrow has started to
become worn. When the disc harrow has become worn, the entire frame
needs to be lowered further towards the ground to achieve the same level of
tilling. This reduces the ground clearance between the lower edge of the
frame and the surface of the ground, which results in an increased risk of
plant residue building up underneath the machine. When adjusting the 2
points at the end of each side, it is important that corresponding adjustments
up/down are carried out on the threaded rods at the front/back. This is to
maintain the same fine-tuning of the working picture behind the centre of the
machine.
