Leakage of hydraulic oils causes long-term damage to the environment. Every year, a significant amount oil is released into environment through accidents and leakages. Biohydraulic minimize risk environmental due their biodegradability lack toxicity. Mobile machines offer great substitution potential for biohydraulic oils. The majority are operated with mineral Furthermore, in view decreasing e...

When subjecting forest products to certification the total environmental load of wood harvesting machinery should also be assessed. In this study fuel, hydraulic oil and lubricant consumption in harvesting operations in Sweden has been examined by using machine data acquired through a questionnaire. The objectives of the study were to assess the contractor and forest company owned harvesters’ a...

Recently, the issue of machine condition monitoring and fault diagnosis as a part of maintenance system became global due to the potential advantages to be gained from reduced maintenance costs, improved productivity and increased machine availability. The aim of this work is to investigate the effectiveness of a new fault diagnosis method based on power spectral density (PSD) of vibration sign...

The study assessed effect of farm machinery on both physical and hydraulic properties agricultural soils used for rice cultivation in northern Ghana.  Two tractor models were the field experiment with tests soil sampling points classified as tyre passage area (TTPA), ploughed (PA) unploughed (UPA). Randomised Complete Block Design (RCBD) 3 blocks, treatments, 9 replications data analysed u...
