Blade Servicing - Progressive Turf Equipment Pro-Flex 120 Operators Manual & 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 and wing 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 out
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 REMOVAL AND INSTALLATION
Replace any blade that is bent, excessively nicked, worn or has any
other damage. Small nicks can be ground out when sharpening.
When replacing mower blades, be aware of blade rotation as blades
rotate in opposite directions. Ensure the cutting edge is facing in the
correct direction
The Pro-Flex 120 is equipped with 4 left hand (LH) rotation blades
and 1 right hand (RH) rotation blade*:

4 LH ROTATION BLADES painted BLACK.

1 RH ROTATION BLADES painted RED
*RH & LH rotation is determined by the top blade tip travel direction
when viewed from above. RH = Clock-wise, LH = Counter Clock-wise
See Page 8 / Page 9 for individual deck blade rotation direction.
A 1" diameter pilot centers the blade on the spindle with two 1/2"
grade 5 fasteners. When installing blades, be sure that the spindle
pilot is properly seated in the blade and the fasteners are in good
condition and properly tightened per the chart on at the beginning of
this section.
