J3078/4 specifies a uniform test method for measuring the contribution to operator environmental temperature provided by a heating, ventilating and air conditioning system operating in a specific ambient environment. The method might not determine the complete climatic environment of the operator since this is also affected by heat load from sources other than those on the machine, for example solar heating. J3708/6 is to be used in conjunction with J3078/4 to determine more accurately the complete heat loading on the operator enclosure. Minimum performance levels for the machine’s operator enclosure heating, ventilating and air conditioning systems are established in J3708/4.

This SAE Recommended Practice is intended to serve as a reference for the amount of torque that a Power Take-Off can induce on the transmission mounting pad. This document will apply to six-bolt, eight-bolt, and rear mounted power take-offs.

This SAE Standard describes methods for evaluating the performance of the systems detection device, the minimum detection areas behind the machine, the visual and audible information presented to the operator and ground personnel, and the systems fault detection requirements. Also included are operator system function tests and maintenance procedures. The purpose of this document is to establish performance requirements for a Discriminating Back-Up Alarm System.

This report discusses the use of specialized analytical procedures that can be used to predict the structural behavior of ROPS and machine frame systems subjected to testing as described in SAE Recommended Practice J1040. For practical reasons, these complex calculations require the use of computerized methods. Specific approaches that are thought to be essential to preparing accurate analytical predictions are described. The importance of an experienced ROPS analyst is reviewed. The use of analytical procedures to predict the performance of ROPS is especially desirable for ROPS designed for installation on very large off-road machines, where problems of testing are extraordinarily great, and for predicting the effects of changes to proven ROPS designs before retesting. This report also covers the use of these analytical techniques as ROPS design tools.

The purpose of this report is to record the activities and recommendations of the Ride Meter Task Force assigned by the chairman of the SAE Joint Seating Subcommittee to determine availability of instrumentation to measure operator ride on mobile equipment. The desired characteristics of the meter included relatively low cost, easy to operate, highly portable, and sufficiently rugged to withstand the vibration levels encountered on agricultural or construction machines. It is recognized that a ride meter type instrument with a single numerical output provides only approximate indication of ride vibration quality, but is useful for general field evaluation or overall ride comparisons. A narrow band analysis of the vibration frequency spectrum is recommended for more accurate and complete results.

To provide specifications for lighting and marking of agricultural equipment whenever such equipment is operated or traveling on a highway.

This SAE Recommended Practice provides general design performance requirements and related test procedures for LED “white” lighting unit assemblies, other than signal and marking devices, used on Earthmoving, Road Building, and Maintenance off-road work machines as defined in SAE J1116. This report is intended to serve as a guide to standard practice and is subject to change to reflect additional experience and technical advances.

Minimum performance criteria for service braking systems, emergency stopping systems, and parking systems for off-highway, rubber-tired, self-propelled loaders, dumpers, tractor scrapers, graders, cranes, excavators, and tractors with bulldozer are provided in this SAE Recommended Practice. Refer to SAE J1057 and J1116 (Sections 1.1, 1.2, and 2) for machine identification.

The guidelines for operator and bystander protection in this recommended practice apply to towed, semimounted or mounted flail mowers and flail power rakes when powered by a propelling tractor or machine of at least 15 kw (20 hp), intended for marketing as industrial mowing equipment and designed for cutting grass and other growth in public use areas such as parks, cemeteries and along roadways and highways. The use of the word "industrial" is not to be confused with "in-plant industrial equipment". This document does not apply to: 1 Turf care equipment primarily designed for personal use, consumption or enjoyment of a consumer in or around a permanent or temporary household or residence. 2 Machines designed primarily for agricultural purposes but which may be used for industrial use. 3 Self powered or self propelled mowers or mowing machines. Where other standards are referenced, such reference applies only to the document identified, not revisions thereof.

This SAE Standard includes only those towing winches commonly used on skidders and crawler tractors. These winches are used on self-propelled machines described in SAE J1057, J1116, and J1209. Specifically excluded are those winches used for hoisting operations.

In the main body of this recommendation, conditions are defined for measuring and recording whole body vibration of the seated operator of off-highway self-propelled work machines. The specification of instruments, analytic methods, and description of site and operating conditions allows the measurements to be made and reported with an acceptable precision. The procedure includes means of weighting the vibration level at different frequencies as specified in ISO 2631 (Ref. 1). A standard format for reporting spectral data is recommended. The definitions, instruments, and analytic methods also apply to simulated tests for operator vibration as performed in laboratories. This procedure is a measuring method only and is not intended for the evaluation or selection of seating systems.
