25 Adjustments
Coulter Depth
Adjust coulters to run 13 to 25 mm (1/2 to 1 inch-
es) below the drill openers. Coulter depth can be
adjusted hydraulically for all coulters or manually
for individual coulters.
Hydraulic Control
Make the following adjustment when drilling in lev-
el ground with the seed box half full.
1. Retract tongue cylinder to transfer weight to
coulter toolbar.
Refer to Figure 15
2. Set tongue cylinder so coulters are at desired
depth. Note setting on cylinder gauge so you
can return to the same depth.
NOTE: Use cylinder gauge only as a reference.
Gauge does not measure actual coulter depth.
Refer to Figure 16
3. With coulters and drill lowered to desired
seeding depth, check that hitch frame (1) runs
parallel with ground.
Refer to Figure 17
4. If the hitch frame is not level, remove or re-
place spacers (1) from transport-lift-cylinder
rods until hitch is level.
NOTE: As a reference, 95mm of bushing on the
cylinders is approximately 50mm of coulter depth
with the frame level.
The 5 bushings adjust in 6.4mm increments from
19mm to 146mm.
