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, commonsense 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, attachments
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
mechanism 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.
Attaching a Trailer
The maximum weight of a towed trailer should be less than
800 lbs (363 kg). Secure the trailer with an appropriately
sized clevis pin (A, Figure 20) and clip (B).
Excessive towed loads can cause loss of traction and loss
of control on slopes. Reduce towed weight when operating
on slopes. The surface being driven on greatly impacts
traction and stability. Wet or slippery surfaces can greatly
reduce traction and the ability to stop or turn.
