PTO (Power Take Off)
The PTO connects the tractor to the turbofan.
Make sure you connect the proper end of the PTO to the
tractor. An arrow on the PTO indicates the end that is
attached to the tractor.
The following warning is placed on your PTO shaft for
your safety.
DANGER Rotating drive line contact can cause death –
keep away. Do not operate without all drive-line, tractor
and equipment shields in place, without drive-lines
securely attached at both ends, and without drive-line
shields that turn freely on drive-line.
Hydraulic Drive
Hydraulic Drive Optional for 450 Standard, 500 High
Output, or 540 Extra High Output Turbofans
Hydraulic drive is optional for the 450 Standard turbofan,
500 High Output turbofan, and 540 Extra High Output
turbofan. The hydraulic drive attaches to the turbofan to
produce and maintain the vacuum level.
The desired vacuum is dependent on the correct amount
of oil flow to the hydraulic motor.
Starving the motor of oil will cause the vacuum to drop.
An excessive amount of oil flowing into the motor can
result in damage to the motor or the turbofan.
When attempting to shut off the turbofan, the blade must
be allowed to "spin down". If the flow of oil stops abruptly,
the check valve in the block on the motor will re-circulate
the oil already in the motor helping to prevent damage
to the fan and motor. Still, you should not allow the flow
of oil to stop suddenly. You should move the remote
running the fan to the float position when shutting down
the hydraulic fan. Refer to your tractor’s operators manual
for further information.
You can control oil flow to the motor in one of three
ways:
T81389
—UN—28JUN13
TS1644
—UN—22AUG95
1. With the tractor hydraulic system controls. This is the
most common and recommended method.
2. With a flow control valve (part number FN30SK) that
is optional for the hydraulic motor. For closed-center
tractor hydraulic systems only.
3. With a bypass flow control valve (part number 300954)
that is optional for the hydraulic motor. For all
open-center tractor hydraulic systems. Can be used
with closed-center systems also.
Monosem hydraulic drives are closed center systems.
Contact your Monosem dealer if you tractor has an open
center hydraulic system.
