25P Opener Depth
Refer to Figure 65
The “T” handle
sets planting depth by limiting the how
high the side depth gauge wheels ride relative to the
opener disks. The position of the seed tube itself is fixed
relative to the disks, and is not adjusted.
With the planter raised, lift both side depth wheels
against the stop and measure the depth of exposed
opener disk below it. Do not lift just one wheel, as the
25 Series T handle sets the average depth of both
wheels.
Alternatively, check the actual furrow depth with openers
lowered and pulled forward in field conditions.
To adjust seed depth, pull the “T” handle up and back,
move it forward or aft, and set it back in a different pair of
holes in the scale.
• For shallower planting, move the “T” handle forward.
• For deeper planting, move the “T” handle back.
Check opener down-pressure and press wheel(s) after
adjusting depth. See “25P Series Down-Pressure” on
page 65, and “Press Wheel Adjustment” on page 83.
