1.39 1.39 PREPARING THE TRACTOR
Preparing the Tractor
Prepare the mower for transport: Start the trac-
tor engine and engage the P.T.O. drive. Operate
the override control lever to lift all cutterheads to
the fully raised transport position. Stop the tractor
engine, return to the mower and secure all cut-
terhead suspension arms and outer cutterheads in
the transport position by locking the transport latch
safety locks. Apply a thin coating of grease to all
exposed hydraulic cylinder rods and to the faces of
the diverter valve operating cams.
The TM5490 and TM7490 Trailed Gang Mowers
are designed for use with standard agricultural or
industrial tractors having a minimum power of 45
BHP (TM5490) and 70 BHP (TM7490). They must
also be equipped with a ring-hitch (automatic pick
up hitch) and a 540 rpm, rear P.T.O.
The TM5490 and TM7490 Gang Mowers have
a fully independent hydraulic system which is
powered from the tractor rear P.T.O. The system
is live when the tractor rear P.T.O. is engaged. The
cutterheads may be raised or lowered via a remote
control sited adjacent to the operator.
This procedure is best carried out after attaching
the mower to the tractor, for the first time.
A remote control quick release mounting bracket
is supplied loose with the mower. This should
be attached to the tractor in a convenient posi-
tion according to the operator’s preference. When
choosing this position it is essential that adequate
slack is left in the umbilical cable assembly to
allow for articulation of the tractor and the mower
when turning or negotiating brows of hills, etc.
Serious damage could result if the umbilical cable
assembly becomes stretched or pinched in work.
The control and power cables are housed in a
robust umbilical hose. Secure the tractor end of the
umbilical hose using the mounting bracket supplied
in a convenient position on the tractor. Recheck the
routing of the umbilical cable assembly and ensure
that it is free of pinch points and has adequate
slack.
WARNING: PREVENT ACCIDENTS - Under
no circumstances should the mounting brackets
be attached to the frame or structure of a safety
CAB or ROPS.
