Marker Disk Adjustment

Sharp Object Hazard:
Use caution when making adjustments in this area.
Marker disks may be sharp.

Refer to Figure 41
1.

To change angle of cut, and the width of the mark,
loosen

-inch bolts

holding the disk assembly.

For a wider mark

, increase the angle of the

marker with respect to the tube

. For a narrower

mark

, reduce the angle.

Note: Do not set a marker angle wider than needed to

make a useful mark. Excess angle increases wear
on all marker components.

2.

Tighten bolts

.

Note: Direction of travel

tends to drive the disk angle to

Wide. If bolts are not tight enough, or loosen over
time, disk slips into the Wide mark configuration.

Gauge Wheel Height Adjustment

The YP625PD is factory pre-set for planting on 18 cm
beds.This operating height can be reduced by 5 cm, to
13 cm, but relocating the gauge wheel axles.

Note: For operation on flat ground, do not make this

adjustment. Instead adjust the lift cylinder mounts.
See “Appendix C - Flat Ground Planting” on
page 114.

Refer to Figure 42
1.

Raise the planter. Support the frame with jacks or
stands. Retract the lift circuit to raise the tires off the
ground.

2.

Remove the axle bolts

from the lower holes

.

3.

Re-install the bolts and axles in the upper holes.

Sharp Overhead Object and Pinch/Crush Hazards:
Never allow anyone near the planter when folding or
unfolding the markers. Markers may fall quickly and
unexpectedly if the hydraulics fail. Anyone beneath may be
injured if hit by an unfolding marker, or caught in a folding
