Blade Servicing - Progressive Turf Equipment SDR-90 Operators Manual And Parts Lists

BLADE SERVICING

Always observe proper lock-out procedures when performing
any maintenance work including changing or servicing the
blades. Always remove and retain the ignition switch key,
ensure parking brake is engaged, and block and or support
machine using equipment designed for the task.
Be sure deck safety locks are engaged when working on decks
in the raised position.
Use gloves when handling mower blades. Blades can be very
sharp.
Inspect blades before each use to determine that they are
mounted tightly and are in good condition. Replace any blade
that is bent, excessively nicked, worn or has any other
damage. Small nicks can be ground out when sharpening.
Use only original equipment blades when replacing worn or
damaged mower blades. They are made of special steel alloys
and subjected to rigid heat-treat and inspection requirements.
Substitute blades may not meet these specifications and MAY
BE DANGEROUS.
BLADE SELECTION (SDR-90 Only)
We offer four blade styles for use with this mower:
Fixed high lift
Combined with Progressive‟s high tip speed, the fixed High-
Lift blade „stands‟ grass blades up for a clean cut, even in
damp conditions or at high mowing speeds.
Fixed low lift
Developing less lift than the High-Lift blade, Progressive‟s
Low-Lift fixed blade is ideal for both new growth or sandy
soils where abrasion is a concern but superior cut quality can
never sacrificed. Also requires less tractor horse-power.
Pro-EZ Change System (Available in high or low lift)
Developed with turf professionals in mind:
 Economical as only the tips are changed
 Flat profile fastener extends life, reduces cost
 Standard hand-tools are used for reduced cost and easy
change out
 Lower start-up torque requirement reduces stress on the
complete drive train
 Thinner profile than a standard blade means the tips retain
their sharpness after the equivalent number of mowing hours
Pro-Ez Change Blade System installs on the same blade support
bar as a fixed blade. This allows users to easily swap blade types
as growing conditions or mowing requirements change.
