information will lead to efficient operation and good
working habits. Always operate farm machinery with
safety in mind.
Pre-Start Checklist
Perform the following steps before transporting the
YP2425A Planter to the field.
 Carefully read “ Important Safety Information ” on
page 1.
 Lubricate planter as indicated under “ Lubrication ”
on page 115.
 Check all tires for proper inflation. See
“ Specifications and Capacities ” on page 139.
 Check all bolts, pins, and fasteners. Torque as
shown in “ Torque Values Chart ” on page 154.
 Check planter for worn or damaged parts. Repair or
replace parts before going to the field.
 Check hydraulic hoses, fittings, and cylinders for
leaks. Repair or replace before going to the field.
 Install seed disks appropriate for crop. To change
disks, see “Air-Pro
® Meter Disk Installation
” on
page 81.
Fold/Unfold Lock Overview
The YP2425A planter includes five sets of locks for the
frame, wings and casters:
1. Wing locks: Hooks on the tongue engage locks on
the wings to prevent unfolding in transport. Tongue
must be raised to engage/release. See page 27.
2. Lift cylinder lock channels: These are
operator-installed on a raised plater, these prevent
lowering in transport or when parked. See page 32.
3. Fold cylinder and Caster swing arm cylinder lock
valves: Switch-controlled solenoid valves prevent
motion of the fold cylinders and caster swing arm
cylinders, in transport and field. See page 147.
4. Tongue lock: This engages automatically at unfold,
and lock the tongue/draw bar geometry for field
operations. See page 27.
5. Caster pivot locks: operator-engaged after unfold,
these prevent caster swiveling in the field, which aids
in tracking across hillsides. See page 26.
High Pressure Fluid Hazard:
Relieve pressure before disconnecting hydraulic lines. Use a
piece of paper or cardboard, NOT BODY PARTS, to check for
leaks. Wear protective gloves and safety glasses or goggles
when working with hydraulic systems. Escaping fluid under
pressure can have sufficient pressure to penetrate the skin
causing serious injury. If an accident occurs, seek immediate
medical assistance from a physician familiar with this type of
injury.
