“…When both financial cost parameters are summed up, as only one machine is to be chosen, GRM was responsible for the best results observed by the lowest cost (108.9 R$.ha −1 ). RBC was responsible for the highest costs with fuel, a fact also observed by [64], who stated that the reduction of power consumption and the increase in efficiency of RBCs is an emergent issue.…”

The current scenario of Agroforestry Systems (AFS) worldwide lacks specific machinery, resulting in practically all operations being carried out manually. This leads to a significant physical effort for small-scale farmers and limits the implementation of AFS to small areas. The objective of the study was to evaluate the suitability of existing machines for performing agroforestry tasks. This research utilizes Descriptive Statistics and Exponentially Weighted Moving Average methods to evaluate the data and compare the treatments, where different machines are used to cut Mombaça grass (Megathyrsus maximus Jacq): (i) costal brushcutter (CBC); (ii) tractor-mounted rotary brushcutter (RBC); and (iii) mini grain reaper machine (GRM). The experiments were conducted in Jaguariúna, São Paulo, Brazil. GRM is recommended for achieving greater biomass production, reducing raking time, and minimizing operational costs. CBC is suitable for smaller areas due to its affordability and slow operation, which requires significant physical effort. RBC is recommended for reducing working time, physical effort, and personnel costs, making it suitable for larger-scale contexts.

“…Authors argue that little knowledge is required to operate the machine hence, it can be easily adapted by local farmers in developing agroindustrial countries to eliminate manual harvesting. Furmanov et al [24] examined the reduction of power consumption of rotary brush cutters. The lowest cost and highest productivity were observed in thinning operations with the removal of each 5 th row and selective thinning between these rows, while the highest productivity for the forwarder was obtained with the removal of each 7 th row and selective thinning between these rows.…”

The problem of untimely forest thinning is quite common in today's society. It leads to the emergence of the underbrush, which negatively impacts the growth and development of young trees. Therefore, this work aims to estimate the feasibility of applying a new rotary brush cutter model to eliminate excessive vegetation. The dependence of the tractor's speed when removing underbrush with different diameters of tree trunks was established by performing mathematical modeling to optimize the brush cutter parameters. Three types of flexible inertia cutting devices were investigated: flat knives, sprocket chains, and knife chains. Knife chains are the most optimal choice as they cut plants most efficiently (94.61% and 92.5% for two-year and three-year underbrush, respectively). They also show the lowest energy consumption for underbrush with a trunk between 1 and 2.4 cm in diameter. Further experiments are required to determine if the developed mathematical model can be used for more neglected forestry stands.
