Adjustments
CAUTION
Never install or work on the cutting decks or lift
arms with the engine running. Always stop en-
gine and remove key from ignition switch first.
See the Cutting Deck Operator’s Manual for adjustment
procedures for cutting decks on the Groundsmaster
4500--D and Groundsmaster 4700--D.
Blade Stopping Time
The blades of the cutting decks are to come to a com-
plete stop in approximately five (5) seconds after the
PTO is disengaged.
NOTE: Make sure the decks are lowered onto a clean
section of turf or hard surface to avoid dust and debris.
To verifythis stopping time,have a second person stand
back from the machine at least twenty (20) feet and
watch the blade on one of the c utting decks. Have the
machine operator disengage the PTO and record the
time it takes for the cutting deck blade to come to a com-
plete stop. If this time is greater than seven (7) seconds,
the deck control manifold braking valve (RV) may need
adjustment.
