Lubrication

To help keep the I-series in proper running order,

Cub Cadet recommends the following lubrication inter-
vals be used (adjustable to local conditions). Use a
high quality petroleum grease to lubricate the tractor.

* On 42” timed decks, the idler stop bolt needs to

be readjusted every 10 hours.

NOTE: Lubricate all of the pivot points with a
light coating of oil once a season.

The spark plugs

The spark plugs should be checked, cleaned and

re-gapped on a monthly basis or every 100 hours of
use. The plugs should be replaced every six months or
300 hours of use.

When checking the spark plugs, a dry, light colored

residue on the plugs is a sign of running lean.

If there is a thick, wet, black residue on the plug the

engine is running rich.

There should be a dry tan coating on the plugs.

This would indicate the proper mixture.

To remove/replace the spark plugs:

1.

Remove the spark plug wires on each side.
See Figure 9.1.

NOTE: Do not use metal pliers on spark plug
wires. Damage to the wire can result.
