Product: Groundsmaster® 4500/4700 Jan 25, 2012
Affected Units:
Groundsmaster 4500
Groundsmaster 4700
Models:
30857
30858
Serial Numbers:

290000001 and up
Situation:
Important Information
In certain operating conditions (fast turns, bumpy terrain), the center deck may drift
down after lifting it to “turn around height”. This undesired movement is due to the
parallel design of the lift circuit hydraulics, which can allow independent deck
movement.
Correction:
Toro has designed a Center Deck Lock Kit, which will not allow the center deck to
move once it reaches “turn around height”. Install Deck Lock Kit (119-8633)
to
ensure the center cutting unit will not move once it has been lifted.
