Auxiliary Hydraulic Kit
Yield-Pro Planters
Used with:
• All model year YP1225 and YP1625 (pull type) planters
General Information
These instructions explain how to install the Auxiliary
Hydraulic Kit. When the planter is not in motion, this kit
enables the marker hydraulic circuit to be used to drive
off-planter equipment, such as a seed auger.
Note: These instructions apply only to planters with
markers (which are standard). If your initial planter
order deleted the markers, have your dealer con-
tact the factory for special instructions.
These instructions apply to:
Before You Start
Each kit converts one planter.
For each kit, inventory the contents per the “Parts Lists”
on page 13.
Review the instructions, to make sure the steps are
understood and what tools are expected.
If necessary, move the planter to a dry well-lighted loca-
tion suitable for disassembly.
1. Unfold and lower the planter. Although this kit can
be installed on a folded and/or raised planter,
access to the hose support bracket to be replaced,
and the marker sequence valve, is much easier
when unfolded/lowered.
2. Select the Marker circuit in the tractor. Set control to
float (to drain pressure in that circuit). Shut down
hydraulics.
Secure the tractor if left connected.
“Left” and “Right” are facing in the direction of machine
travel.
