NOTE: Adjust all attachments (de-thatcher and brush) in the same way.
Tighten the groomer height locking nuts
on both sides of the machine.
Re-check the groomer height setting and
if necessary re-adjust.
Once the groomer height is locked off
and checked to be correct you will
then need to lock off the groomer
adjuster nuts.
Do this by holding the bottom nut firm
whilst tightening the top nut against it
by turning it in a clockwise direction.
The act of nipping the two nuts
together will lock them so that they
do not work loose during operation.
The groomer height is now set.
