Section 7 – Lubrication/Maintenance

Danger: Before lubricating or performing maintenance on any part of the corn head, engage the
feeder house lift cylinder safety stops, set the parking brake, turn off the combine engine and
remove the key and hang a warning sign on the operator’s platform. Failure to do so could
result in serious injury or death.

Maintenance can be categorized in three types:

1) Pre-Season Maintenance – This type of maintenance is carried out after the corn head is removed
from storage at the beginning of the season. This is mainly an inspection of fluid levels and ensuring
no damage occurred during storage.
2) In-Season Maintenance – This type of maintenance must be carried out in relationship to the
recommended lubrication guide. This type of maintenance should not be postponed.
3) Post-Season Maintenance – This maintenance is carried out at the end of the season to
ensure and preserve the efficiency as well as proper operation of the corn head for the following
season.

Important: Failure to complete the required maintenance may cause poor performance and
unnecessary downtime. Follow lubrication and maintenance intervals as noted on Table 7.3.1
for normal harvest conditions. If running in down corn or severe conditions follow lubrication
and maintenance intervals indicated on Table 7.3.2. Failure to follow this maintenance schedule
may cause component failure.

Pre-Season Maintenance

Careful inspection of the corn head following removal of the corn head from annual storage will prevent
any damage due to fluid leaks or other damage incurred during storage.

1) Inspect the corn head for any fluid leaks. Replace any seals that are leaking or damaged.
2) Inspect the corn head for any damage that may have occurred while in storage.
3) Check all fluid levels according to the instructions in Section 7.4.
4) Attach the corn head to the combine and operate at low speed to ensure all parts of the corn
head rotate.

In-Season Maintenance

Careful inspection and service of the corn head prior to operation each day will prevent unnecessary
breakdowns and delays in the field. Make the following checks and adjustments prior to operation each day:

• Clean the corn head of all dirt and debris periodically to aide in inspections.
• Always verify that there is no loss of oil or broken parts in areas to be greased. Be alert for
loose/missing hardware and tighten/replace as required.
• Lubricate the corn head according to the instructions on Tables 7.3.1 and 7.3.2 of this manual.
• Pay special attention to the condition of the stalk chopper knives, if equipped. If damage
occurs replace the knives immediately. Always replace the knives in pairs to maintain proper
balance.

Danger: Stop harvest immediately if any missing or damaged chopper knives are
observed. This is essential to prevent further damage to the corn head and to
prevent serious injury or death.
