Installation Instructions 1
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
“Left” and “Right” are facing in the
direction of machine travel. An orientation rose in the line art illustrations
shows the directions of Left, Right,
Front, Back, Up, Down.

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.

If the hose can reach the ground, protect the open
end from contamination, for example, by clamping
a plastic bag over the end. If the strainer is due
for maintenance, this is an ideal time to clean it.
4. Loosen the hose clamp on the outlet port of

4 Ground Drive Fertilizer Pump
Install New Components
Determine Ground Drive Location
These instructions do not specify a precise location for
mounting the new ground drive, due to the wide variety
of factory configurations and end user modifications.
The hose connections to the fertilizer feed line, strainerto-pump line and pump-to-distribution manifold permit
considerable flexibility in placement of the strainer and
pump.
The strainer (on a new mount) requires a vertical surface with mounting holes, typically the inside or outside
of either plate of the wing drive shaft bracket. Unless
you add hose, it needs to be within existing hose length
of the feed line.
The optimal placement for the drive unit itself is halfway
between rows (row units or row unit pairs in twin-row),
and within hose length of the strainer and manifold. If
you add hose, you have more flexibility.
These instructions assume that the strainer is mounted
inside the wing drive shaft brackets, on the inboard
plate, and the ground drive assembly is mounted about
a foot outboard of the wing drive shaft brackets.

The valve assembly attaches to the mount
using two bolts already present in the valve, which
pass through the holes in the short bent end of the
mount.
21. Hand-position valve/strainer assembly / to
determine:
• mounting clearance,
• hose clearance,
• operator access,
• clearance for valve operation,
• preferred inlet elbow orientation, and
• clearance for strainer maintenance.
22. Apply pipe sealant to male threads of adaptor
and screw it into the inlet port of valve . Apply
sealant to the male threads of elbow and screw
it into adaptor , adjusting final orientation to
desired angle.
Note: Do not use tape sealant on pipe threads. Tape
fragments will clog strainer and block orifices.

To complete the installation the Driving and Driven
sprockets need to be mounted on the drive. If you do
not know the next fertilizer rate desired, sprocket
change does not need to be completed at this time.
Setup and use of the Ground Drive Fertilizer Pump is
described in the 401-226M Operator’s Manual, a copy
of which is included in this kit.
To change sprockets, remove the knob securing the
drive guard , and remove the guard. Remove the linch
pins securing the sprockets on drive shafts and storage shafts . Exchange sprockets per the Drive Type
table of the Fertilizer Rate chart, and re-pin.
