LUBRICATION
Lubricate the unit at the locations shown in Figures
15 through 18 as well as the following lubrication
points.
Grease:
• front caster wheel axles & yokes
• deck lift pivot blocks
• mower deck spindles
• mower deck idler arm
Use grease fittings when present. Disassemble parts
to apply grease to moving parts when grease fittings
are not installed.
Not all greases are compatible. Ferris Red Grease
(p/n 5022285) is recommended, automotive-type
high-temperature, lithium grease may be used when
this is not available.
Oil:
• control handle pivots
• seat plate pivots
• deck lift pivots
• discharge chute hinge
Generally, all moving metal parts should be oiled
where contact is made with other parts. Keep oil and
grease off belts and pulleys. Remember to wipe
fittings and surfaces clean both before and after
lubrication.

1. Remove the 1/4-28 bolt (A, Figure 18) screwed
into the front caster and install a 1/4-28 grease
fitting.
