Initial evaluation of emissions originating from modern agricultural tractors
An initial study was conducted to quantify whole-body vibration (WBV) emissions levels found upon a limited range of modern agricultural tractors (5 examples), when operated in controlled conditions (traversing ISO ride vibration test tracks). Vibration emission levels were found to increase with travel speed and surface roughness, but reduce as vehicle size (mass) increased. The presence of vehicle (cab and/or front axle) suspension systems also served to reduce the degree of vibration increase with travel speed.
