ASSEMBLY
DEALER SET-UP INSTRUCTIONS
The mower as received from the factory is virtually completely assembled and requires minimum time to
complete assembly ready for sale.
ASSEMBLY
Select a suitable work area large enough to allow for lowering of the wings. Use extreme caution when
connecting the mower to the tractor. The mower should be securely resting at ground level or setting on blocks.
Keep hands and feet from under the mower deck and clear of pinch points between the tractor hitch arms and
mower pins.
1. Use the implement jack to raise the implement tongue until it is even with the tractor drawbar. Insert the
jack into the jack adapter in the implement tongue and swivel it so that it is vertical. Follow the instructions
on the jack. Install the jack retaining pin. Measure the height of the tractor drawbar and raise the implement
tongue to the same height.
On a fully assembled unit, do not release the Wing Retaining Strap until the hoses are
attached to the tractor and the Wing Cylinders are filled with oil. Always keep bystanders
away while raising and lowering the wings
To lower the wings, hook the hydraulic hoses to the tractor. From the Operators
Seat use the tractor hydraulic control levers to fill wing cylinders with oil. Keep
coworkers and bystanders away from the implement while filling. For implements
with the wings in the raised or transport position, filling the cylinders should raise
the wings slightly and loosen the wing retaining lock. DO NOT release the wing
Transport Bar/Latch if there is a force on the lock. Use tractor hydraulic control
levers to lower the wing(s). Continue to hold the control lever until both wings are
down and the wing cylinders are fully retracted or extended. Continue to cycle the
cylinders several times by raising and lowering the wings fully to remove any
trapped air. If there is sponginess during the raising cycle, this may indicate that
air is entrapped in the hydraulic circuit. Continue to cycle the cylinders until all
sponginess is removed.
The implement wings should lower slowly when they are allowed to float down
and are not powered down. This is a safety feature built into the system. If the
wings fall rapidly, have the cylinders repaired before operating the implement.
