Service and Repairs
CAUTION
Never install or work on the cutting units or lift
arms with the engine running. Always stop en-
gine and remove key first.
Blade Stopping Time
The blades of the cutting deck are to come to a complete
stop in approximately 5 seconds after the cutting deck
engagement switch is shut down.
NOTE: When checking blade stopping time, make sure
the decks are lowered onto a clean section of turf or hard
surface to avoid dust and debris.
To verify blade stopping time, have a second person
stand back a safe distance from the machine and watch
the blade on one of the cutting decks. When the machine
operator disengages the cutting decks, record the time
it takes for the blade to come to a complete stop. If this
time is greater than 7 seconds, the braking valve (BV)
on the h ydraulic manifold needs adjustment (see Brak-
ing Valve Adjustment in the Adjustments section of
Chapter 4 -- Hydraulic System).
