In Indonesia, rice production varies from province to province, resulting in both large and small disparities between provinces. East Java, Central Java West Provinces have the highest production. contrast however, total consumption per year is highest. linear regression, coefficients are same for all regions, while each region sometimes has different influencing factors, spatial diversity. Con...

Goal. To determine and justify the conditions under which use of double/triple tires wheeled energy vehicles instead single ones will be appropriate. Methods. Theoretical studies were carried out using basics theory tractors agricultural machines. The object research was MTZ1221 multipurpose-weed tractor, front axle studied in variants with single, double, triple tires. Soil compaction passage ...

Beginning in the mid-1970s, standard small-bale forage balers began to be replaced by large-bale balers in the agricultural industry. The chance for serious injury or death to workers grows with the size and weight of bales. Bales that weigh more than 750 pounds put workers at especially high risk. According to NIOSH analysis of data from the Bureau of Labor Statistics (BLS) Census of Fatal Occ...

There is a need for vehicles to maneuver when there are traffic jams, overcome narrow streets and various obstacles. This leads increased requirements dynamism maneuverability of vehicles.
 The authors present the results development research steering control vehicle, which provides maneuverability. Such circumstances significantly affect increase in wheeled vehicles, including tractors, u...

The improvement and reliability of the agricultural machines provided a revolution in the human activities facilitating the production of commodities of agribusiness. Though, the efficiency of the tractor, well as the occurrence of accidents also depends on the level of fatigue to which the operator is submitted. Between the ergonomic factors that affect the operator machine, noise and vibratio...

OBJECTIVE The purpose of this systematic review was to evaluate the effectiveness of roll-over protection structures (ROPS) as an engineering control for prevention of fatalities from farm tractor roll-overs. METHODS Using a systematic approach to literature searching, relevant studies from peer-reviewed journals, technical and government reports, and unpublished reports were retrieved. Studi...

Traction performance tests were run by Alberta Farm Machinery Research Centre personnel on fourwheel drive tractors with single, dual and triple rubber tires and on track tractors with two and four rubber belt tracks. Traction power delivery efficiency was compared in various tilled and untilled soil conditions representative of the Northern Great Plains. Various ballast set-ups and tire inflat...
