Maintenance

Proper servicing and maintenance is the key to long

implement life. With careful and systematic inspection,

you can avoid costly maintenance, downtime, and repair.

Always turn off and remove the tractor key before making

any adjustments or performing any maintenance.

Crushing Hazard:

Always have transport locks in place when working on

implement. You may be severely injured or killed by being

crushed under a falling implement.

1. After using your planter for several hours, check all

bolts to be sure they are tight.

2. Remove excess slack from chains. Clean and use

chain lube on all roller chains as needed.

3. Lubricate areas listed under “Maintenance

Schedule” on page 40.

4. Replace any worn, damaged, or illegible safety

labels by obtaining new labels from your Great

Plains dealer.
