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.
