Full title and description

ISO 10448:2021 — Agricultural tractors — Hydraulic pressure for implements. This International Standard specifies the characteristics of hydraulic pressure supplied by agricultural tractors for connecting hydraulic devices on implements, to permit interchangeable use of various implements using remote cylinders and other hydraulic devices.

Abstract

The standard defines the required hydraulic pressure characteristics and connection intent for tractor-to-implement hydraulic circuits so that implements with remote cylinders and other hydraulic devices can be used interchangeably on agricultural tractors designed for interchangeable implements. It is a short, focused document updating the earlier 1994 edition.

Scope

Specifies the characteristics of hydraulic pressure from agricultural tractors for connecting hydraulic devices on implements, to permit interchangeable use of various types of implements using remote cylinders and other hydraulic devices. The standard applies to agricultural tractors intended for interchangeable implements.

Key topics and requirements

• Definition of the required hydraulic pressure characteristics that tractor implement circuits should provide to ensure interchangeable operation of implements.
• Requirements relevant to connections for hydraulic devices such as remote cylinders and other implement-mounted hydraulic actuators.
• Intended to enable compatibility and safe interchangeability between tractors and a range of hydraulic implements.
• Updates and replaces the earlier ISO 10448:1994 edition.

Typical use and users

Used by tractor and implement manufacturers, agricultural machinery designers, testing and conformity-assessment bodies, and standards committees to ensure hydraulic supply compatibility and to design implement interfaces that conform to internationally recognized hydraulic-pressure characteristics. Also referenced by procurement, safety, and regulatory stakeholders concerned with implement interchangeability.

Related standards

Replaces ISO 10448:1994 (withdrawn). It is part of the body of ISO standards on tractors and agricultural machinery produced by ISO/TC 23/SC 4 and may be cross-referenced by other tractor and implement standards dealing with mounting, power take-off, hydraulic systems, and safety. The 2021 edition has also been recognized as an industry-relevant document by sector bodies (for example ASABE has listed ISO 10448:2021 as a recognized document).

FAQ

Q: What is this standard?

A: ISO 10448:2021 is an International Standard that specifies the hydraulic pressure characteristics supplied by agricultural tractors for connecting hydraulic devices on implements so those implements can be used interchangeably.

Q: What does it cover?

A: It covers the characteristics of tractor-supplied hydraulic pressure for connecting remote cylinders and other hydraulic devices on implements and applies to tractors intended for interchangeable implements. It is a short technical specification (3 pages) focused on pressure/connection characteristics rather than detailed hydraulic system design.

Q: Who typically uses it?

A: Tractor and implement manufacturers, design engineers, standards committees, test labs, and procurement/specification teams that require assurance of hydraulic compatibility between tractors and implements.

Q: Is it current or superseded?

A: It is the current (published) edition as of 12 July 2021 and it supersedes ISO 10448:1994. Users should check national adoptions or sector recognitions (for example ASABE recognition) for any country-specific notes.

Q: Is it part of a series?

A: It is part of the suite of standards addressing tractors and agricultural machinery prepared by ISO/TC 23/SC 4; it is a single-part standard focused on hydraulic pressure characteristics rather than a multipart series.

Q: What are the key keywords?

A: Agricultural tractors, hydraulic pressure, implements, interchangeability, remote cylinders, hydraulic connections, ISO 10448.
