Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following

This document was prepared by Technical Committee ISO/TC 127, Earth-moving machinery,
Subcommittee SC 2, Safety, ergonomics and general requirements.
This second edition cancels and replaces the first edition (ISO 24410:2005), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— addition of safety requirements
— addition of informative annex regarding the mechanics of a skid steer loader quick coupler
— addition of width dimensions for narrow skid steer loader attachment mounting frame

Introduction
Quick couplers typical to skid steer loaders are now used on other types of compact products, e.g.
compact loaders, compact tractors, compact rough-terrain forklift trucks. The growth of the use of this
style quick coupler with other products has resulted in the need to provide guidance regarding the
design principles of this quick coupler system.
The previous version of this document only provided the dimensional requirements for the mounting
frame on the attachment. Dimensions for the quick coupler itself were not provided as these dimensions
are dependent on the design of the quick coupler. This revision of the document also does not provide
dimensional requirements for the quick coupler itself, however it does provide guidance for the quick
coupler engagement system.

Earth-moving machinery — Coupling of attachments to
skid steer loaders
1 Scope
This document provides for the interchangeability of attachments on skid steer loaders by establishing
requirements for the quick coupler system including dimensional limits for the attachment mounting
frame. These quick couplers are typically used on skid steer loaders as defined in ISO 6165.
NOTE 1 Skid steer loaders can use other styles of quick couplers but the coupler would not be interchangeable
with attachments designed to comply with this document.
NOTE 2 The requirements of this document can be applied to quick couplers used on other compact machines.
NOTE 3 Quick couplers used on small skid steer loaders and some compact tool carriers can have a different
width requirement than provided in this document. See Annex B.
