Maintenance and Lubrication
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.
General Maintenance
1. After using your drill for several hours, check all bolts
to be sure they are tight.
2. Replace any worn, damaged or illegible safety
decals by obtaining new decals from your Great
Plains Dealer.
Storage
1. Clean the Small Seeds Attachment as necessary. Be
sure that the seed boxes are completely cleaned
before storing.
2. Store the drill inside if possible for longer life.
Chain Installation
Whenever mounting a chain, make sure the clip at the
removable link is oriented to minimize snags.
Refer to Figure 13 (arrow shows chain direction)
Install clip with open end facing away from direction of
chain travel (striped arrows in routing diagrams).
Chain Slack
Check slack within the first 8 hours of operation and
tighten idlers as necessary.
Refer to Figure 14, which, for clarity, greatly exaggerates
slack, and omits the idlers.
1. Measure the span for allowable slack:
Locate the longest span of each chain (usually the
span which does not run through the idlers).
2. Determine the ideal slack:
Long chains (over 36in/91cm):
1 ⁄
4
inch per foot
Vertical short chains:
1 ⁄
4
inch per foot (2.1cm/m)
Horizontal short chains:
1 ⁄
2
inch per foot (4.2cm/m).
3. Measure the slack by acting at a right angle to the
chain span at the center of the span, and deflecting
in both directions. The slack is the distance of the
movement.
4. Adjust the idlers for ideal slack.
