LOWERING THE DECKS
Before lowering the decks, make sure that there are no obstacles or people in the area
that the decks could come in contact with while lowering to the ground. First, fully
retract the 3 main cylinders, which will disengage the locks. Pull on the lock release
pull rope to release the wings and rear lift from their locking position, and hold until
the decks are on the ground. Lower the main wing decks and rear deck until they are
completely sitting on the ground. Once the 3 main decks are on the ground, lower the
outside wing decks until they are completely on the ground.
Place both hydraulic levers (main decks and outside wing decks) into their float
positions before mowing.
Tractor control valves must be equipped with float function. Both
hydraulic circuits must be in “FLOAT” position during mowing or
damage to the mower may result.
RAISING THE DECKS
Before raising the decks, ensure that the PTO on the tractor is disengaged and wait
until the PTO comes to a complete stop. To raise the decks, first raise the outer wing
decks. When fully raised, pull on the lock release pull rope so the wings do not latch
into the ProLift-N-Turn position before rising all the way. Proceed with lifting the
main decks into transport position by pulling the appropriate hydraulic lever.
Once all hydraulic cylinders have fully collapsed, ensure that all three wing locks are
in their locking position before removing the hydraulic hoses from the tractor, or
transporting the mower. Make sure that none of the hydraulic levers are in the float
position.
MOWING
Once the tractor and mower are situated in the field to be mowed, follow the
“Lowering the Decks” section. Once lowered, move both hydraulic ports into float
position.
Engage the PTO just above idle and bring the mower up to full PTO speed, Engage to
appropriate gear in the tractor and proceed to mow.
It is advisable to mow double headlands on each end of the field to allow for a
sweeping turn at the end of a row as opposed to a tight turn. Sweeping turns will limit
the scuffing of turf as the mower negotiates a turn.
Ensure tractor engine is at idle when engaging PTO. Some
tractor PTO arrangements engage very abruptly; engaging PTO at
higher engine speeds can cause premature component failure.
