NOTE: Proper inflation of tire pressure contributes to longer tire life and proper
flotation for field operations. Tire inflation pressures listed are recommended initial
settings. Some soil conditions and operating environments may dictate deviation
(on Pneumatic Packer Tires Only) from the recommended settings. Contact Seed

for additional information and advice if needed.
NOTE: If you do change your tire pressure, ensure that your opener is correctly
placing your seed at the depth you require.
