Control Locations for Off-Road Work Machines
- Ground Vehicle Standard
This SAE Standard applies to Construction, General Purpose Industrial, Agricultural, Forestry, and Specialized Mining categories of off-road, self-propelled work machines, as defined in SAE J1116. Powered industrial trucks and agricultural equipment, other than the basic agricultural tractor, are excluded from the scope of this document. The document defines positions for convenient placement of hand- and foot-operated controls derived from the overlapping reach capability of large and small operators. The large operator approximates the 95th percentile male, and small operator approximates the 5th percentile female of the U.S. population.
This document defines zones in which controls used by a seated operator would ordinarily be placed, and is intended as a guide for the design of the operator compartment controls. Constraints peculiar to individual machine or user applications may require modification to these defined zones.
The established zones are based upon singular reach capability: appropriate consideration must be made for effort, displacement, and simultaneous operation of two or more controls.

The Human Factors Technical Committee (HFTC) is part of the Construction, Agriculture, and Off-Road Machinery (ConAg) Council. The HFTC is responsible for standards related to the design, development and application of human factors engineering (man-machine interface). The goal is to enhance human performance on construction, general purpose industrial, agricultural, forestry and specialized mining machinery. Categories include off-road, self-propelled work machines as defined in SAE J1116. The following work machines are specifically excluded: powered industrial trucks. The committee maintains a liaison with the SAE Off-Road Machinery Technical Committee, SAE Agricultural Tractor Standards Committee, ISO/TC127 and ISO/TC96, CIMA, and EMI. The HFTC is comprised of four subcommittees dedicated to creating, preparing and maintaining all relevant specifications, standards, and requirements. These subcommittees include: HFTC SC1 Controls, Visibility, Anthropometrics, Accessibility HFTC SC2 Machine Displays and Symbols HFTC SC4 Operator Seating and Ride HFTC SC6 Operator Accommodation Participants in the SAE HFTC committee include OEMs, suppliers, consulting firms, government, and others across the construction and agriculture industries.
