Productivity studies in forest operations are often carried out on new equipment, or on equipment being used in new conditions. Understanding how stand and terrain parameters impact the productivity of harvesting machines is important for determining their optimum use. Such information is normally presented as a productivity or efficiency function; that is, a regression equation that best represents the data. Most studies establish that piece size is the dominant predictor that impacts overall… Expand
Investigation of Feller-Buncher Performance Using Weibull Distribution
With the advancement of technology in forestry, the utilization of advanced machines in forest operations has been increasing in the last decades. Due to their high operating costs, it is crucial toExpand
Impact of Slope on Productivity of a Self-levelling Processor
Slope is a major factor affecting forest harvesting machine productivity. As ground-based harvesting methods are generally cheaper than the alternatives, forest managers need to know whenExpand
Effect of Feller-Buncher Model, Slope Class and Cutting Area on the Productivity and Costs of Whole Tree Harvesting in Brazilian Eucalyptus Stands
The operational productivity and costs of tree felling operations can be influenced by several factors, among which, the machine characteristics, slope class, the cutting area and the individualExpand
Assessing the effects of site factors on the productivity of a feller buncher: a time and motion analysis
We evaluated, for the first time in Turkey, the productivity of a feller buncher during clear-cut operations of two Brutian pine stands located in Canakkale, northwestern Turkey with differentExpand
Performance Analysis of Log Extraction by a Small Shovel Operation in Steep Forests of South Korea
TLDR
In South Korea, logs for low-value products are primarily extracted from harvest sites and transported to roadside or landing areas using small shovels using a model to estimate productivity under various site conditions, and small-shovel productivity was significantly correlated with stem size and total travelled distance.

The effect of the number of log sorts on mechanized log processing productivity and value recovery
New Zealand’s forestry supply chain handles a wide range of log products to meet domestic and export market demands and to maximize returns to the forest grower. With a strong customer focus inExpand
Productivity of harvesters and forwarders in CTL operations in northern Sweden based on large follow-up datasets
Modern computerization facilitates data-gathering from forest machines, and offers new opportunities to develop models for predicting productivity in forest harvest operations. In this study, weExpand
Performance of two shear heads for harvesting biomass in hardwood stands in France
Abstract The increasing demand for energy wood in Europe is accompanied by the development of new harvesting tools to mobilize forest biomass, notably hardwood biomass. Two logging operations areExpand
Productivity in partly mechanized planting operations of willow short rotation coppice
Abstract Biomass for energetic use can be procured from various sources including willow short rotation crops (WSRC). The feasibility of willow crops, however, is dependent on the costs incurred byExpand

Time consumption analysis of the mechanized cut-to-length harvesting system
TLDR
Stem size, tree species and bucking affected the cutting, whereas timber density on the strip road, the average driving distance, load capacity, wood assortment and the bunching result of the harvester operator had an effect on the forest haulage performance. Expand

Performance and cost of a new mini-forwarder for use in thinning operations
TLDR
A new model of mini-forwarder, specifically designed for thinning operations, fitted with four bogies and provided with a much longer wheelbase, is likely to be safer than tracked machines when surmounting obstacles, and it certainly offers a much smoother ride to the operator. Expand
