Product Information

AIRGUARD Seed Brakes

AIRGUARD Seed Brakes are an innovative product designed to provide added protection during seeding. They are available in two models: 7360 with 1 1/2 inch (38mm) OD hose and 7350 with 1 1/4 inch (32mm) OD hose. The Seed Brakes come with adapters, including 7340 with 1 inch OD hose, 11/8 inch and 11/4 inch OD hose, 7330 with 11/4 inch OD hose, 7394 with 1 inch OD hose for use with 7330/7350, 13/16 inch and 7346 with 11/8 inch OD hose for use with 7330/7350, 7375 with 11/8 inch OD hose for use with 7340/7360, 17/16 inch and 7388 with 13/16 inch OD hose for use with 7340/7360, 7344 with 11/4 inch OD hose for use with 7340/7360, and 7392 with 17/16 inch OD hose for use with 7340/7360.

The Seed Brakes come with SABRE clamps and optional adapters. You will need a hose cutter and other tools during installation.

Product Usage Instructions

1. Before installation, make sure you have all the required tools and parts.
2. Mark the hose and cut the seed tube at the desired location using your hose cutter. Attach all of the Seed Brakes to every cut hose using the supplied SABRE clamps. Only attach the inlet side of the Seed Brake at this time.
3. Start the tractor and turn on the fan. Set the air speed to your highest RPM used for seeding. This will make it easier to balance the air flow on each Seed Brake in the following steps.
4. Choose a Seed Brake in the center of the drill or where the airflow is strongest and insert a 6-inch piece of hose to the exit port. Use a wind meter to measure the wind speed exiting the Seed Brake. Record the observed target speed as this will be used to balance all of the other Seed Brakes.
5. Measure each Seed Brake exit port using the 6-inch piece of hose. If the wind speed is lower, remove some of the washers to increase the speed to match the recorded target. Small shim equals 1 mph, medium shim equals 2 mph, and large shim equals 4 mph.
6. Once all of the exhaust ports have been balanced, install the hoses on all of the exit ports of the Seed Brakes. Tighten every exhaust port cap and place a dab of silicone on the threads before it is tightened to prevent the caps from vibrating off.

Congratulations! You are now ready to seed with the added protection of AIRGUARD Seed Brake Technology. For more information or support on using AIRGUARD Products, visit our support page at airguardproducts.com or call 1-604-744-0070.

SUPPLIED PARTS

INSTALL IN 6 STEPS

STEP 1

Choose a location on your drill to install the Seed Brakes. There are many places for installation, at the manifolds, or between the frame and the opener. If you install at the manifolds, note that sags in the hose or longer hose lengths may cause plugging issues with lower air speeds. For most drills, it is recommended placing the Seed Brakes 6-12” above the opener. Ensure that the Seed Brake will not interfere with the trip mechanism or hit the bottom of the drill frame when the trip is engaged. If the brake has to be placed further up the hose, for proper clearance, ensure there are no dips on the hose after the brake.

STEP 2

Mark the hose and use your hose cutter to cut the seed tube at the desired location on every hose. Attach all of the Seed Brakes to every cut hose using the supplied sabre clamps. Only attach the inlet side of the Seed Brake at this time.

STEP 3
Start the Tractor and turn on the fan. Set the air speed to your highest RPM used for seeding. This will make it easier to balance the air flow on each Seed Brake in the following steps.

STEP 4
Choose a Seed Brake in the center of the drill or where the airflow is strongest and insert a 6” piece of hose to the exit port. Take the wind meter and measure the wind speed exiting the Seed Brake. Record the observed target speed as this will be used to balance all of the other Seed Brakes.

STEP 5
Start measuring each Seed Brake exit port using the 6” piece of hose. If the wind speed is lower, remove some of the washers to increase the speed to match the recorded target. Small Shim equals 1 mph , Medium Shim equals 2 mph, and Large Shim equals 4 mph. (approximately)

STEP 6
Once all of the Exhaust ports have been balanced proceed with installing the hoses on all of the exit ports of the Seed Brakes. Next tighten every exhaust port cap. It is very important to place a dab of silicone on the threads before it is tightened to prevent the caps from vibrating off
