Ground Drive Fertilizer Pump
Yield Pro Planters
Used with:
• 2006- Yield Pro
® 1225/1625
General Information
These instructions explain how to install the Ground
Drive Fertilizer Pump enhancement kit on a planter
which already has a fertilizer pump coupled to the meter
drive system. Installing this kit eliminates the need to
adjust the pump whenever seed rates are changed.
This kit is not needed for 2007+ planters, as their
optional fertilizer systems already include these components. This kit requires a pre-existing fertilizer system,
and re-uses many existing system components.
These instructions apply to:

Before You Start
Each kit converts an entire planter. Inventory the contents per “New Parts: Kit 407-148A” on page 7.
Review these instructions, and make sure you understand which existing system components are re-used,
and where they are located. The new components, and
the existing components to be re-used or discarded, are
located on the back of the left wing of the planter, about
halfway out on the toolbar.
Tools Required
• pipe sealant such as RECTORSEAL® NO. 21
• basic hand tools
• a second or third person for Step 28
Notations and Conventions

2 Ground Drive Fertilizer Pump
Pre-Assembly Preparation
Refer to Figure 2,
which depicts the planter with row units removed for clarity.
The ground drive pump is installed on the left wing,
at or near the location of the existing shaft-driven
fertilizer pump.
1. Unfold the planter. The planter must be raised for
unfolding, but may be raised or lowered for all
tasks prior to Step 28. If left raised, installed lift/
transport locks. Secure the tractor.
2. Flush the existing fertilizer system with water. Fluids will drain off during updates to the plumbing.
!
CAUTION
Exercise caution when working with a used fertilizer system.
The chemicals are usually very caustic. Unless you fully
operate the planter while flushing with water, some chemicals
will drain from components during disassembly. Trace
amounts may remain in any case.
