Gauge/Transport Wheel
Adjustments
The gauge/transport wheels serve two functions:
1. When the planter is lowered, the wheels establish
the heights of their respective sections, nominally a
tool bar height of 26 inches (66 cm) above the
planting surface.
The main and trailing wheels are not adjustable
in height.
The wing gauge wheels may be slightly raised or
lowered by adjusting a nut on the cylinder rod. See
“Wing Leveling, Inboard End” on page 23.
2. When the planter is raised, all of these are the
transport wheels. The main wheels
are rigid, and
aid steering. The trailing wheels are full castering.
The gauge wheels are usually adjusted only to bring all
sections to level.
Marker Adjustments
There are six adjustments for markers:
• Disk Angle
Even if your row spacing rarely changes, you may
need to adjust disk angle for soil conditions and
planting speed.
• Marker Extension
Once set for a specific row spacing, this only needs
periodic checking to ensure the clamp is secure.
• Marker Support Wheels
Three bolt holes are available for adjusting height.
• Shear Bolt Replacement
If a marker hangs up on an obstruction, a bolt at the
fold is designed to fail.
• Chain Length
This needs to be set if the chain is replaced. It may
also need adjustment for unusual terrain.
• Marker Speed
Once initially set by your dealer, this rarely needs
modification.
Sharp Overhead Object Hazard:
You may be injured if hit by a folding or unfolding marker.
Markers may fall quickly and unexpectedly if the hydraulics
fail. Never allow anyone near the planter when folding or
unfolding the markers.
