All requests pertaining to ANSI/ASABE AD500-1:2014 MAR2015 standard should be submitted to ASABE. This standard was reviewed and approved for adoption by the ASABE Power and Machinery Tractors and Tractor Implement Interface/PTO Technical subcommittees, and has been formally approved. This adoption along with the adoption with deviations of ISO 8759-1:1998 and ISO 8759-2:1998 and the identical adoptions of ISO 500-2:2004, and ISO 500-3:2004 replaced ASAE S203.14 and ASAE S513. Rear mounted PTOs are addressed in the ISO 500 adoptions, front mounted in the ISO 8759 adoptions. Adopted by ASABE December 2010; approved as an American National Standard January 2011; revised October 2011; revision approved by ANSI November 2011; replaced with adoption with deviations of ISO 500-1:2014 February 2015; approved by ANSI March 2015.

0.4 This standard has been approved as an American National standard by ANSI (American National Standard Institute). The original content of ISO 500 and ISO 8759 was based on ASAE S203. 0.5 This standard deviates from ISO 500-1:2014 as follows: 0.5.1 Inclusion of the following references: 0.5.1.1 ANSI/ASABE AD6489-3:2004, Agricultural vehicles — Mechanical connections between towed and towing vehicles — Part 3: Tractor drawbar 0.5.1.2 ASAE S207, Operating Requirements for Tractors and Power Take-Off Driven Implements 0.5.1.3 ANSI/ASABE S604.1, Safety for Power Take-off (PTO), Safety for Power Take-off (PTO), PTO Drive Shafts, and Power Input Connection (PIC) for Agricultural Field Equipment 0.5.2 Over speed requirements: 0.5.2.1 Tractors capable of driving the 540 r/min shaft in excess of 630 r/min, the 1000 r/min shaft in excess of 1170 r/min, and the 1300 r/min in excess of 1520 r/min shall also include a suitable warning of operation in excess of those speeds. 0.5.2.2 If a shiftable PTO is provided, a means shall be employed on the tractor to prevent over speeding of a type 1 tractor PTO shaft in excess of 630 r/min, a type 2 or 3 tractor PTO shaft in excess of 1170 r/min, or a type 4 tractor PTO shaft in excess of 1520 r/min. 0.5.5 The safety for power take-off (PTO), PTO drive shafts, and power input connection (PIC) provisions specified in ANSI/ASABE S604 remain in effect. Text of ISO 500-1:2014, Agricultural tractors — Rear-mounted power take-off types 1, 2, 3 and 4 — Part 1: General specifications, safety requirements, dimensions for master shield and clearance zone follows.
5 PTO-speed requirements for shiftable PTO 5.1 Should more than one ratio between the engine speed and the PTO rotation speed be provided, any change of ratio shall be indicated. In addition, specific design measures shall be taken to ensure that unintentional changes of ratio, particularly in changing to a higher rotational speed, cannot occur. This safety device shall operate each time the PTO is engaged. 5.2 A means to indicate when the PTO is operating at which nominal speed shall be provided. 6 Safety requirements 6.1 The PTO master shield, as shown in Figure 1 and Table 2, shall be supplied by the tractor manufacturer and shall be fixed to the tractor. If the same degree of safety protection is reached and the clearance zone is respected, equivalent protection devices (e.g. towing hook or clevis supports) can be used instead of the master shield. In this case, provisions shall be made for anchoring the restraining member of the PTO drive shaft guard. 6.2 If necessary, the PTO master shield or a part of the shield can be movable without detachment from the tractor to facilitate attachment of the PTO drive shaft. The movable portion of the master shield shall be resistant to unintentional movement when in the operating position. The master shield can be made of flexible material.
