Adjusting Tool Bar Height
” on page 26 for how to
check tool bar height. To change the tool bar height, add
or remove master lift cylinder rod spacers
, in the com-
binations shown in the chart at the bottom of this page.
To change spacers:
1. Perform a Lift operation (page 36).
2. Add or remove spacers. Unused spacers are stored
on rods loops welded to the cart-implement link (not
visible in figure). If you store spacers on hoses,
make sure they cannot slide into locations where
they interfere with implement operation.
Note: Chart values are approximate. Press wheel set-
tings, disk wear and manufacturing tolerances can
cause actual heights and depths to vary from chart
values. Choose spacer combinations based on ac-
tual field measurements.
Note: The cylinder has 5.7cm (2
1
4
in) of exposed rod
when fully retracted, for a minimum tool bar height
of 58.4cm (23.0in). All spacer combinations that
increase tool bar height above the minimum must
be a stack of at least 5.7cm in height.
Note: Each full (1)cm or (1)inch of spacer stack height
change changes the tool bar height by 2cm or 2in.
Note: Do not use a spacer stack taller than 10.2cm
(4.0in), or the furrow will be too shallow, or there will
be no furrow at all.
