Important Notes

• Verify SpeeCo part number S07093900 before ordering

• This listing is for a 5/16" x 2-1/4" square PTO pin, not a complete PTO shaft or driveline assembly

• Confirm compatibility with your specific tractor, implement, or PTO shaft assembly

• Do not assume compatibility with all agricultural equipment or PTO-driven attachments

• Verify the original equipment manufacturer's fastening hardware specifications

• Confirm the required 5/16-inch nominal pin diameter

• Verify the specified 2-1/4-inch pin length

• Confirm whether the manufacturer's stated length refers to overall length or usable pin length

• Check the required grip length and available mounting clearance

• Verify the square PTO pin configuration matches the original equipment requirements

• Similar-looking PTO pins may differ in diameter, length, head design, retaining mechanism, or intended application

• Do not assume compatibility based solely on nominal pin dimensions

• Confirm that the replacement pin fits the designated mounting holes and PTO connection components

• Verify compatibility with the existing PTO shaft, yoke, coupling, and retaining hardware

• Confirm the required strength and load specifications for the intended application

• Do not assume a particular shear rating, torque capacity, or load capacity without manufacturer documentation

• Verify whether the pin is intended for retention, torque transmission, or another designated function

• Do not substitute this pin for a calibrated PTO shear bolt or other engineered overload-protection component

• Never replace a manufacturer-specified shear pin or shear bolt with an unapproved fastener

• Verify whether the application requires a retaining clip, locking mechanism, or additional fastening component

• Do not assume additional retaining clips, washers, or mounting hardware are included unless specified

• Follow the equipment and PTO shaft manufacturers' installation and maintenance instructions

• Shut off the tractor or equipment engine before servicing the PTO connection

• Disengage the PTO and allow all rotating components to stop completely

• Remove the ignition key and secure the equipment against unintended starting

• Never inspect, install, or remove PTO fastening hardware while the driveline is rotating

• Properly support attached implements and driveline components before removing retaining hardware

• Never remove a retaining pin from a connection that is under load or tension

• Wear appropriate protective equipment when servicing PTO assemblies

• Inspect the PTO shaft, yoke, coupling, and mounting holes for wear, cracks, or deformation

• Check the replacement pin for bending, cracks, damaged retaining features, or other defects

• Clean the mounting area before installing the replacement pin

• Ensure the pin is fully inserted into its designated mounting location

• Verify that any required retaining or locking mechanism is properly engaged

• Do not force installation if the pin does not match the original fastening configuration

• Do not grind, drill, bend, weld, or otherwise modify the pin to accommodate an incorrect fit

• Confirm that the installed pin does not interfere with PTO shaft rotation or surrounding components

• Ensure all PTO shaft guards and protective shields are correctly installed before operation

• Never operate PTO-driven equipment with missing or damaged driveline guards

• Inspect the connection periodically for looseness, excessive wear, or unintended movement

• Replace bent, cracked, heavily worn, or improperly retaining pins immediately

• Avoid operating equipment with missing, loose, or incorrectly installed PTO fastening hardware

• Verify that all PTO connections are properly secured before engaging the driveline

• Test equipment operation according to manufacturer instructions after installation

• Confirm current specifications, equipment compatibility, and included quantity before ordering
