This book is one in a series of Minimum Industry Standards produced by

Arboriculture Australia Ltd and the New Zealand Arboricultural

Association in consultation with the national arboriculture community in

both countries. These industry peer-reviewed documents provide a ‘body

of knowledge’ which is shared by practitioners and can be used as the

basis for training, dissemination of skills and professional development.

This Standard covers the work tasks of preparing, maintaining and using

stump grinders, as well as a range of considerations for selection of an

appropriate grinder and applicable safety considerations.
