“…Also in this case, the procedure of a preliminary setting of the PTO speed before switching it on was not immediate for the novices. The described difficulties in interpreting icons and signals on or near the controls is in line with some previous studies reporting low comprehension scores of safety pictograms affixed to agricultural machinery (Caffaro & Cavallo, 2015;Caffaro et al, 2017a). This outcome should be examined more in depth since icons, signals and pictograms are supposed to be self-explanatory and able to quickly communicate concepts and instructions, compared to a written language (Edworthy & Adams, 1996).…”

At the end of the 20 th century the adoption of the Continuously Variable Transmission (CVT) was one of the disruptive technological advances in agricultural tractors. Several changes in the Human Machine Interface (HMI) of the tractor cab have been introduced to accommodate this technology. HMIs are known to raise issues about their ease of use; however, this topic has been under-investigated in the agricultural sector. The present study introduces a method to investigate the perceived ease of use of the HMI of agricultural tractors equipped with technological innovations. The HMI required to manage a CVT tractor was evaluated by sixteen tractor drivers (8 novices and 8 experts). During the first contact with the machine and after having performed two targeted tasks with the tractor, participants filled in a questionnaire about the ease of use of the controls and of the touch-screen display, and evaluated the general perception of ease of use, safety, quality and solidity of the machine. The trial pointed out some significant differences between novices and experts, thus confirming the validity of the proposed method. In particular, novice users showed some difficulties when interacting for the first time with the HMI of the CVT tractor working station, whereas experts did not report similar difficulties. Thus, expertise seems to play a role in determining the quality of the interaction with the HMI. Training interventions should be designed to help novices in increasing their expertise effectively, avoiding effort and errors and improving user's comfort and system performance.Additional keywords: tractor cab; ergonomics; expert; novice; questionnaire; user trial.

“…Results clearly indicated respondents' preference for non-technical farm safety and health resources. Several other studies have shown similar results indicating many resources on agricultural safety are cluttered and overwritten, so the information is not read [16,17,30,31], a salient point for safety and health professionals to consider as they produce educational materials. Literacy levels and educationally appropriate communication schemes should be considered when creating materials for a range of recipients.…”

“…Looking at undeveloped countries use of communication modes such as radio messaging as a perceived and effective method of transferring agricultural knowledge to farmers [13,14], helps more advanced societies develop more progressive electronic communication channels. Countries across the globe seek ways to meet the educational needs of their farmers [13][14][15][16][17][18]. Although this project investigates U.S. farmers, the data collected is pertinent to other countries safety and health education.…”

Abstract:As farm demographics change, it is important to create relatable, research-based safety and health materials, and deliver information via preferable methods. Three data collection methods (focus groups, surveys via National Agricultural Statistics Service, and face-to-face interviews) were administered to farmers in seven Midwestern states. Farmers were coded as retired, organic, residential/lifestyle, limited resource (<$249 K gross annual income), or large resource (>$250 K gross annual income). Issues addressed hazard perceptions, injury prevention measures, resource preferences and delivery, and preferred communication channels. Findings indicated that gender, age, and farming operation influence Personal Protective Equipment (PPE) use and communication preferences. Retired farmers and those with a higher percentage of income from farming are more likely to use radio as a communication medium. Research results will inform the creation of web-based, customizable educational materials for use by safety and health professionals and the public. Audio Public Service Announcements (PSAs) were recorded to reach farmers who indicated a preference for radio.

“…This brings operators into close contact with components that may present a risk of entanglement [15,17,18]. Risky behavior is also the result of operators not reading operation manuals, particularly the safety warnings [19,20] and often not noticing or understanding the safety instructions and the pictograms affixed on the machine [21,22].…”

Following formal opposition by France, the harmonized safety standards regarding manually-loaded wood chippers (EN 13525:2005+A2:2009) which presumed compliance with the Essential Health and Safety Requirements (EHSR) required by the Machine Directive (Directive 2006/42/EC), have recently been withdrawn, and a new draft of the standard is currently under revision. In order to assess the potential impact of the expected future harmonized standards within the Italian context, this study has examined the main issues in implementing EHSRs on wood chippers already being used. Safety issues regarding wood chippers already in use were identified in an analysis of the draft standard, through the observation of a number of case studies, and qualitative analysis of the essential technical interventions. A number of agricultural and forestry operators and companies participated in the study, pointing out the technical and economic obstacle facing the safety features requested by the pending new standard. It emerged that the main safety issues concerned the implementation of the reverse function, the stop bar, and the protective devices, the infeed chute dimension, the emergency stop function, and the designated feeding area. The possibility of adopting such solutions mainly depends on technical feasibility and costs, but an important role is also played by the attitude towards safety and a lack of adequate information regarding safety obligations and procedures among users.
