Seed-Lok Lock Up
Optional Seed-Lok firming wheels provide addi-
tional 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.
Refer to Figure 80
NOTE: Side gauge wheel and seed meter is re-
moved for clarity.
To lock up Seed-Lok wheels, raise drill. Rotate
lock-up handle (1) 90 degrees down on top of
opener body. Push up on Seed-Lok wheel (2) until
wheel arm latches up.
Opener disk blades may be sharp. Use caution when
making adjustments in this area.
To unlock Seed-Lok wheels, pull up lock-up han-
dle (1). Seed-lok is spring loaded so it will snap
back into place.
Tongue Spacer Block
If the drill does not pull straight or if the drill wan-
ders back and forth while being towed it may be
necessary to adjust tongue spacer block.
Refer to Figure 81
1. Loosen nut on 5/8” x 6”x 7 3/4” U-bolt (1) and
slide block forward or backward to it line-up
with the block on the opposite side of the
tongue.
2. Remove nut from 5/8” x 6” x 7 3/4” U-bolt (1).
Remove block (2) and add or remove shims
(3) as necessary.
Note: Make sure when retightening U-bolt that
the block lines-up with the block on the oppo-
site side of the tongue.
Note: It is normal for the tongue assembly to
rotate slightly when the wings move up and
down independently. Adjusting tongue shims
will not eliminate this.
