firming wheels provide additional
seed-to-soil contact. The wheels are spring loaded and
do not require adjusting. In some wet and sticky
conditions the wheels may accumulate soil. To avoid
problems associated with this, you can lock-up the
firmers.
Refer to Figure 74 (which depicts a row unit with discs, side
depth wheels/arms and press wheels removed for illustrative
purposes - removal is not necessary for lock/unlock)
To lock up Seed-Lok
®
wheels:
1. Raise planter. Insert lift assist cylinder locks.
2. Lift Seed-Lok

lock-up handle until lever stop is
free to rotate.
3. Rotate lever stop to side/idle position . Release
lock-up handle .
4. Push up on Seed-Lok
®
wheel until wheel arm
latches up .
To release a locked-up Seed-Lok
®
:
1. Insert a

in tool drive tip in the tool hole of the
handle . Alternatively, lift up on the wheel .
2. Rotate the handle clockwise (handle arm up) until
the Seed-Lok

wheel releases at the latch point
and falls free.
3. While holding the handle up, rotate the raised portion
of the lever stop
under both sides of the handle
at the arm end. Remove the tool.
Press Wheel Adjustment
The press wheels close the furrow which gently presses
the soil over the seed to ensure good seed-to-soil
contact for even emergence.
To provide consistent seed firming, the press wheels are
free to move downward from their normal operating
position. This system maintains closing/pressing action
even if the row unit arm is lifted when the disks encounter
obstructions.
Note: Engage the lever stop under the handle when
Seed-Lok
®
is in use. If left disengaged , a furrow
obstruction could cause unintended lock-up.

Higher press wheel down pressures reduce the down
force on the main row unit shank components, such as
the openers. High press wheel settings may require an
increase in overall row unit down force. See page 52.
