Opener Depth (Press Wheel Height)
Refer to Figure 106
After the opener pressure is set, opener depth
is con-
trolled by the press wheel adjustment. Attached to the
rear of each opener is one of several optional press
wheels. The press wheels close the furrow and gently
press soil over the seed while also providing depth con-
trol for the opener. To adjust the position of the press
wheel, which automatically changes the seeding depth of
the opener, lift the “T” handle
located on top of the
opener and slide it forward or rearward until the
seeding depth is correct.
Moving the handle:
forward plants shallower, and
rearward plants deeper.
A spring loaded pin holds the “T” handle at the setting to
maintain the proper depth. Lift the opener frames slightly
to take the pressure off the “T” handles when adjusting
the press wheel depth.
Note: The opener pressure setting controls the soil firm-
ing pressure on the press wheel as well as the disk
penetrating force. DO NOT use more opener down
pressure than necessary to obtain the desired
opener penetration and to maintain the proper firm-
ing action over the seed. Set the planting depth with
the depth controlling press wheel and only use
enough opener pressure to cut the proper seed
groove and maintain the desired soil firming action.
Excessive opener force will lead to excessive wear
and damage of the opener components.
If press wheels are lifting off ground, increase hydraulic
down pressure.
If press wheels are digging into ground, reduce hydraulic
down pressure.
