General “Musts”:
- Follow manufacturer’s installation, maintenance, and operation recommendations/specifications.
“Musts” for Double Swivel Brackets & Flat Bar:
- Swivel Brackets: Install bushings in both swivel bracket bolted connections to allow break-away coupling device (BACD) to move freely - generally 80 degrees side to side and 30 degrees up and down.
- Flat bar Installation:
- Two bolted connections to toolbar support.
- Single bolted connection to swivel bracket. This bolted connection is not to be connected to the toolbar support.
“Musts” for Other Components & Items Installed On/Around BACD:
- Bleed valves on both sides of BACD.
- 350-400 psi/NH3 rated hydrostat/rain cap when withdrawal hose is mounted on the toolbar and not the nurse tank.
- Discharge “jumper” hose must be long enough to allow full movement and separation of BACD - see mfg. specs.
- Toolbar components/components in assembly with the BACD must not impede the its operation.
- Display manufacturer-specific connection/disconnection instructions to be readily visible near the BACD. Parker-Pioneer requires both the aluminum ring around the female half of the BACD and the instruction decal posted near their BACD.
Recommended placement of BACD:
- Attach support holding the BACD assembly to toolbar frame - NOT the toolbar hitch.
- Position BACD as close as possible over the toolbar/nurse tank hitch connection point.
- Position BACD at least 24 inches above the toolbar/nurse tank hitch connection point during field application.
The goal of the last two recommendations is for maintaining consistent hose length through turns, free from entanglement.
