BS ISO 10448:2021 pdf download – Agricultural tractors — Hydraulic pressure for implements This document specifies the characteristics of the hydraulic pressure from agricultural tractors to connect hydraulic devices on implements, to permit interchangeable use of various types of implements using remote cylinders and other hydraulic devices. It applies to agricultural tractors intended for interchangeable implements. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.
