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 Packer Tires Only) from the recommended settings. Contact

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.
