Installing RowFlow Liquid System (Sidedress)
Liquid system
Installaon of liquid tank, pump, lines, etc. is le to the discreon of the grower.
RowFlow system
Refer to RowFlow Installaon Guide to install components of the RowFlow system. It will be
required to have the 20/20 SeedSense Display, Cab Control Module, 20/20 SeedSense Tractor
Harness, CAN Extension, and RowFlow Module installed on the tractor & sidedress applicator. A
li switch or height sensor will be necessary for the RowFlow Liquid system to operate. The li
switch or height sensor will either plug into the RowFlow Base Harness (in conguraons where
this harness is used) or the Sidedress Base Harness.
Hydraulic Motor
If installing a new Precision Planng Hydraulic Motor (727105), please refer to installaon guide
included with motor for installaon instrucons. The motor may be aached to the liquid pump
with a direct coupler or a chain & sprocket combinaon.
Pressure Sensor and Flow Meter
The Pressure Sensor (727301) should be installed into a diagnosc “T” (not provided by
Precision Planng) somewhere between the liquid pump and the applicaon. Placement of the
sensor is not crical. The grower should understand that dierent pressures can be measured
at dierent points (main line versus individual row line) and where the sensor is installed is the
only point at which pressure can be measured. NOTE: Threaded ng for the Pressure Sensor is
¼” NPT.
The Flow Meter (727305/727306) should be installed between the liquid pump and the
distribuon to the rows. All ow should pass through this meter. The Flow Meter should be
installed vercally with approximately six inches before and aer that are free of any
impediments and sharp objects. There is no specic direcon of travel to factor into installaon.
The green ow sensor threads all the way into the housing and then locked with the jamnut.
NOTE: Thread tape or sealant should be used on all threaded connecons, ow meters, and
pressure sensors.
Connecng Components
With Sidedress Base Harness – 727310 – Connect the two Cinch connectors on the Sidedress
Base Harness to the RowFlow Module. The Pressure Sensor and Flow Meter Sensor will connect
to their respecve plugs on the Sidedress Base Harness. Connect the CAN extension from the
Cab Control Module to the Sidedress Base Harness and then connect the height sensor harness
to the Sidedress Base Harness.
The hydraulic motor harness (for the motor driving the liquid pump) will be connected to the
Drive Motor (8-pin Deutsch) connecon on the Sidedress Base Harness.
With Sidedress Sensor Harness – 727307 – Connect the 8-pin Deutsch connecon to the Drive
Motor 1 plug on the RowFlow Base Harness (MUST be plugged into Drive Motor 1 plug). The
Pressure Sensor and Flow Meter harness will connect to their respecve plugs on the Sidedress
Sensor Harness. Connect the 4-pin AMP round connector to the AUX plug on the RowFlow Base
Harness to pull power for the Pressure Sensor. Height sensor and CAN connecon will be made
with the RowFlow Base Harness .
The hydraulic motor harness (727111 - for the motor driving the liquid pump) MUST be
connected to the Drive Motor 2 (8-pin Deutsch) connecon on the RowFlow Base Harness.
