H. LUBRICATION
There are five lubrication points on the rough cut mower -- one spring-loaded idler pivot, two
caster wheel pivots, and two blade spindles. Lubricate at approximately 10 hr. intervals or more
often as required in dusty conditions. Lubricate the blade spindles 2-5 pumps every 50 hours.
(The bearings have trash guard seals to hold the seals in place during lubrication.) Lubricate with
a high grade of pressure gun grease.
Note: Do not over grease blade spindles. Blade spindles are initially greased at the factory.
Greasing before 50 hrs. may cause bearing seal damage which will result in premature
bearing failure.
