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 deck 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.
Place the hydraulic control lever into the float positions before mowing.
Tractor control valves must be equipped with float function.
Hydraulic circuit 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, 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 the hydraulic circuit 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.
