Ag Spray 28 ft Boom with 17 Quickjet Diaphragms and Bracket

Ag Spray standard boom assembly, 28 feet wide with 17 Quickjet diaphragms and a bracket, for compatible 3-point sprayers.

Choose the matching boom assembly

Model 368-8-8767 is Ag Spray’s standard 28 ft boom assembly. It has 17 Quickjet diaphragms and a mounting bracket. The boom is an attachment, not a complete sprayer, tank or pump. Check the sprayer frame and mounting arrangement before ordering. It is offered for Ag Spray’s 110-, 150- and 200-gallon three-point units. The standard boom is distinct from Pro-Series and shock-absorber configurations, which use separate model numbers.

Treat the boom as part of the application system

The 28 ft dimension describes the boom’s listed span, not the area that can be treated accurately on every pass. Nozzle choice, height, pressure, ground speed and overlap affect the application pattern. Start calibration by confirming nozzle spacing and operating speed, then measure the output collected from each outlet. Use the spray product label for the target rate and nozzle type, and calibrate the assembled sprayer with its intended settings before applying material.

Check the spray pattern across the full width

A long boom can deliver uneven output if an individual outlet is worn or obstructed. During calibration, compare flow across the assembly rather than checking only the center. Replace nozzles outside the tolerance set by the application equipment guidance. A visible streak or gap in a test pattern can also point to a height or overlap problem. Set boom height and pressure for the chosen nozzle, then confirm the pattern with clean water before filling the tank.

Plan clearance and transport

Measure the tractor, sprayer frame and storage route before mounting a 28 ft assembly. The extended boom needs room to fold or be secured for transport according to the sprayer’s instructions. Keep the tips clear of the ground and nearby structures while moving through gates, along a barn wall or around parked equipment. Confirm that the bracket matches the host frame and that the supplied mounting hardware is available before installation.

Keep model numbers straight when servicing

Keep model 368-8-8767 in the sprayer’s service record so replacement parts can be matched to this standard boom. Retain the full code when ordering a diaphragm or related component. After service changes a nozzle, pressure or operating speed, check the output again; those adjustments affect delivery across the span. Follow the sprayer instructions for installation and the selected product label for use conditions.

Assembly and application setup

Directions for use

Confirm the mount and frame compatibility with the host sprayer's instructions before installation. Set nozzle type, pressure, boom height and travel speed for the product label and intended application. Calibrate with the assembled sprayer and verify outlet uniformity before use.

Cautions

Use the chemical product label and sprayer instructions for application rates, personal protective equipment and operating limits. Do not infer a spray rate from the boom width or number of diaphragms.
