the rear position is up then the tractor hitch point is too low. If the front position is up and
the rear position is down then the tractor hitch point is too high.
Before beginning work, ensure that all decks are level. Ensure the mower is adjusted by
using one of the six positions available (see fig. 6) on the front hitch of the Flex tongue
so that it will operate level on the ground surface

Raising the Mower Decks and the Automatic Lock Up System
To lock the mower decks into a secure position, do the following (see fig. 12):
Raise the three decks by means of the tractor hydraulics until the three locking hooks
(2) ride up over the locking pins (1). Allow the mowers to float back down so the crook
of the locking hooks sit securely over the pins and bracket.
Once the mower decks are raised, it is possible to lock the wings in a 90 degree vertical
position for transport safety. Manually rotate the wing decks, they will pivot on the front
and rear draw bars (12) up enough for the transport lock (11) to be positioned under the
wing arm (3).
Bolt the metal transport brace (13) into the holes in the front draw bars (12) for added
safety when the wing units are in the 90 degree vertical position (see fig. 12).
To lower the mowers, proceed as follows:
Raise the three decks with the tractor hydraulics. When they are fully raised, pull the
cord (10) tied to the unlocking lever (9) (this will pull the hooks away from the pins and
mounting bracket), and lower the decks with the tractor hydraulics. Release the cord
once the pins and mounting bracket are past the hooks
