SAE J1194, Rollover Protective Structures (ROPS) for Wheeled Agricultural Tractors

Published by the American Society of Agricultural and Biological Engineers, St. Joseph, Michigan www.asabe.org

ASAE  J1194   November  2016

NOTE: Although SAE J1194, Rollover Protective Structures (ROPS) for Wheeled Agricultural Tractors, is stabilized, ASABE technical committee MS 23/2/2, Ag Tractors ROPS, recommends the use of the state-of-the-art ROPS standards, which are available through the ASABE Technical Library and are as follows:

1) ASABE/ISO 5700, Tractors for agriculture and forestry — Roll-over protective structures — Static test method and acceptance conditions; and

2) ASABE/ISO 3463, Tractors for agriculture and forestry — Roll-over protective structures (ROPS) — Dynamic test method.

3) ASABE/ISO 12003-2 Tractors for agriculture and forestry — ROPS on narrow tractors — Part 2: Rear-mounted ROPS

Access to the cited SAE standards are also available through ASABE.

Approved by ASABE Committee MS-23/2/2 August 27, 2024.

1. Scope

1.1  Fulfillment of the intended purpose requires testing as follows:

1.1.1  A laboratory test, under repeatable and controlled loading, to permit analysis of the ROPS for compliance with the performance requirements of this SAE Standard. Either the static test (6.1) or the dynamic test (6.2) shall be conducted.

1.1.2  A crush test to verify the effectiveness of the deformed ROPS in supporting the tractor in an upset attitude.

1.1.3  A field upset test under reasonably controlled conditions, both to the rear and side, to verify the effectiveness of the protective system under actual dynamic conditions. (See 6.4.1.1 for requirements for the omission of this test.)

1.1.4  In addition to the laboratory and field loading requirements, there is a temperature-material requirement (see 7.1.2).

1.2  The test procedures and performance requirements outlined in this document are based on currently available engineering data.

1.3  Purpose―The purpose of this document is to establish the test and performance requirements of a rollover protective structure (ROPS) designed for wheel-type agricultural tractors to minimize the frequency and severity of operator injury resulting from accidental upsets. All self-propelled implements are excluded.
