Machine Operation
NOTE: Operate two-fold or three-fold row markers with the
tractor's hydraulic valve in float position.
Chain adjustment is critical. Adjust chain with second stage of
marker in vertical position and first stage in horizontal position.
Chain must be adjusted so third stage of marker is pulled
out as soon as second stage begins outward travel. Chain
stretches with use and needs routine adjustment. It may be
necessary to twist chain for a finer adjustment.
Marker chain is PROPERLY ADJUSTED if marker blade
pushes dirt 30 cm or less as marker completes fold into field
operating position. Chain should have some slack when marker
is in field operating position.
Marker chain is TOO LOOSE and should be adjusted if marker
blade pushes dirt more than 30 cm as it completes the fold into
field operating position.
Marker chain is TOO TIGHT if it will not allow marker blade to
follow ground contour and chain is tight when marker is in field
operating position.
