Wheel Bearings
Pump grease into the hub until grease comes out
around the seals. Lift the wheel off the ground. Move the
tire in and out to check for end play. Check for rough-
ness in the bearing by rotating the wheel. If the bearings
are rough they should be inspected and replaced if
necessary.

Seed and Chemical Meter Chains
Lubricate all chains at intervals to maintain freedom at
every chain link joint. Use a multipurpose spray lubricant
on chains, because it penetrates into the rollers on the
chain. Spray chains if planter is going to be idle to pre-
vent the chains from rusting and becoming stiff. Stiff
chains will cause metering inaccuracies.
Gauge Wheel Module
Lubricate gauge wheel module links every 50 hours.
