Operating Instructions
This section covers general operating procedures.
Experience, machine familiarity and the following
information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
Pre-Start Checklist
1. Carefully read “Important Safety Information” on
page 1.
2. Lubricate planter as indicated under “Lubrication”
on page 104.
3. Check all tires for proper inflation. See “Tire
Inflation Chart” on page 127.
4. Check all bolts, pins and fasteners. Torque as shown
in “End of “Appendix A - Reference Information”.”
on page 140.
5. Check planter for worn or damaged parts. Repair or
replace parts before going to the field.
6. Check hydraulic hoses, fittings and cylinders for
leaks. Repair or replace before going to the field.
7. Be sure hydraulic hoses are securely held out of the
ball swivel area at hitch. Failure to do so could cause
hoses to pinch requiring hose replacement.
Wing Lock Overview
Refer to Figure 12 and Figure 13
The YP1225A & YP1625A planters include four sets of locks for the frame and wings:
1. Transport hooks behind the wing pivots:
These prevent the planter frame from fully lowering
when folded. The planter frame is raised to allow the
wings to clear the hooks. See page 20 and 26.
2. Wing locks at mid-tongue and inside wing casters:
These prevent the planter from unfolding while in
transport. The tongue (hitch) is raised to allow the
hooks to clear the locks. See page 21 and 26.
3. Transport lock channels at wing caster cylinders:
These lock channels prevent the frame from fully
lowering during transport and maintenance. They
are installed prior to folding, and removed after
unfolding. See page 22 and 26.
4. Lift cylinder lock channels above frame pivots:
These lock channels are only required during
maintenance. However, if installed, they must be
removed after unfolding. See page 22 and 89.
High Pressure Fluid Hazard:
Check all hydraulic lines and fittings before applying pressure.
Escaping fluid under pressure can have sufficient pressure to
penetrate the skin. Fluid escaping from a very small hole can
be almost invisible. Use paper or cardboard, not body parts,
and wear heavy gloves to check for suspected leaks. If an acci-
dent occurs, seek immediate medical attention from a physi-
cian familiar with this type of injury.
