The purpose of this SAE Standard is to provide a uniform method of defining specification definitions for articulated, rubber-tired log skidders. Reference SAE J1112 for specification definitions of skiddergrapples.

This SAE Recommended Practice identifies and defines the specifications most commonly used to describe articulated rubber-tired forwarders. The illustrations used are not intended to be descriptive of any existing machine or dictate a combination needed for a particular logging situation. The dimensions indicated are basic and may be supplemented by the individual machine manufacturer.

The term "Mobile forestry machines" is intended to include those off-road machines which are designed especially for, or adapted to be used in, the planting, site preparation, harvesting, processing, and transporting of trees. The diversity of machines and systems falling within this scope prohibits detailed specifications, and therefore recommendations are of a general nature.

This document applies to off-road forestry work machines defined in SAE J1116 or ISO 6814.

This SAE Standard describes a uniform method to calculate and specify swing performance characteristics of material handlers, knuckle boom log loaders, delimbers, feller bunchers, harvesters, processors, and other knuckle boom material handlers. It establishes definitions and specifies machine conditions for calculations and tests. This document applies to knuckle boom log loaders as defined in SAE J1209 and SAE J2055 and to certain forestry equipment defined in SAE J1209 and ISO 6814 that have rotating upper-structures such as feller bunchers, harvesters, processors, and forwarders. Included in the definition of knuckle boom log loaders are behind the cab and rear-mounted log loaders not having their own power supply.

This SAE Recommended Practice identifies and defines the specifications most commonly used to describe high-speed steel track and articulated rubber-tired clam bunk skidders. The illustrations used are not intended to be descriptive of any existing machine or dictate a combination needed for a particular logging situation. The dimensions indicated are basic and may be supplemented by the individual machine manufacturer.

This SAE Standard provides a uniform method to calculate the lift capacity of knuckle-boom log loaders and certain forestry equipment. It establishes definitions and specifies machine conditions for calculations. This document applies to knuckle-boom log loaders as defined in SAE J1209 and SAE J2055 and certain forestry equipment defined in SAE J1209 that have a rotating upper-structure such as feller bunchers, forwarders, harvesters, and behind the cab or rear-mounted knuckle-boom log loaders not having their own power supply. It does not apply to harvesters that are incapable of lifting a tree or log completely off the ground. This document applies to those machines that are crawler, rubber-tired, and pedestal or stationary mounted.
