Operating the Tractor
540 Attachment Recommendations
GENERAL
This rear PTO was designed and tested with the 540
RPM rear tiller sold by Simplicity Manufacturing. There
are a wide variety of other 540 attachments available
from numerous manufacturers. It is impossible for us to
test every one of them. There are a few basic, common-
sense criteria that can be used to determine whether
these attachments are suitable for use with your tractor.
In general, any attachment that:
• stalls the engine,
• requires the clutch to be toggled on and off while
starting, or
• takes longer than 3 seconds to reach operating
speed is too large.
PTO BOX OUTPUT SPEED & HORSEPOWER OUTPUT
This rear PTO box is designed to output a maximum of
18 horsepower at 540 RPM. Therefore it should only be
used to run 540 RPM attachments that require 18 HP or
less.
Using this PTO box to run attachments that require
more than 18 HP or an input shaft speed other than
540 could result in poor performance, shortened
equipment life, or equipment damage, and will void
the tractor warranty. Improper use can also create
an unsafe condition resulting in injury.
START-UP AND STOPPING LOADS
This PTO can be used with direct drive attachments that
have small start-up and stopping loads like tillers or
mower decks.
DO NOT use this PTO box with attachments that require
a large amount of torque to start: for example, attach-
ments such as direct drive chipper/shredders and large
silo blowers cannot be used because their starting and
stopping loads may damage the PTO clutch.
Large attachments that have their own clutching mecha-
nism to lessen the load on the PTO box during starting
and stopping may be used provided they do not exceed
the 18 horsepower limit.
OVERLOAD PROTECTION
Any attachment used with this PTO box MUST have
shear pin(s), shear bolt(s), a slip clutch, or some other
device to prevent PTO box damage if the attachment
should jam.
